Johnson / Evinrude Small Outboard Fuel Pump Rebuild - Repair or Service

[@ronaldrichards91]

This was one of the best videos on youtube!

[@ExtremeDIYGuy]

Thank you, I noticed that the few other videos didnt give enough detail so wanted to make sure I included everything I could on properly placing the components. Hopefully this helps!

[@Rockers1121]

@@ExtremeDIYGuy I did the little test as well, put the pump on my outboard today, ran the engine for just a second,(even tho my impeller isn't working correctly) .. I'm positive the pump is working as it should. Should have that Evinrude running like a top pretty soon...... I do have a question tho. So I have an old metal gas tank, it was rusted out when I got it, I threw a bunch of gravel in it and shook it around for 20 min or so, then I filled it with vinegar and let it soak overnight. That seemed to clean the tank really well. I rinsed it out with gas then I filled it, then I rebuilt that fuel pump. But I also put on a fuel filter just after the bulb, just to insure that the gas is clean before it flows through my freshly built pump. Will that filter make that pump work harder then it should? Hope that isn't a dumb question ... I'm probably over thinking it.

[@ExtremeDIYGuy]

@@Rockers1121 I wouldn't think so. The fuel filter shouldn't impede the flow of gas by very much. I think it's a good precaution to take to help protect the pump and engine.

[@jamesmull2832]

@@ExtremeDIYGuy i put my fuel pump back together 5 different times and when i blow thru it its just free flowing air like blowing thru a straw any advice would help???

You have to have hands like a surgeon!

[@angusmacdonald7193]

We were expecting a fuel filter and had no idea what we were doing when we started pulling this thing apart. What a crazy contraption. Followed your video then searched for that stupid plastic piece on the small spring and found it in the cockpit by some miracle. Using your video got the engine working but it kept dying after a minute or two. Rebuilt the filter again paying real close attention to that friggin spring to make sure it didn't fall over and now everything works. Really appreciate the detailed video. Now we're back in the water.

[@ExtremeDIYGuy]

Good deal! I'm glad you found the part and that the video was helpful!

Lol I just did the same exact fuel pump watching this video as I did it, It goes to a 1972 Evinrude fisherman, I just put new points and condenser's in it too, now I'm waiting for a new impeller. ... Gonna see how the engine runs when I'm done with that. If it still runs a little funny then I'll rebuild the carburetor. This video helped a lot ! Saved me 120 bucks for a new fuel pump. I think .. I haven't tested the fuel pump yet, I just now got done rebuilding it. We shall see in a few days after I rebuild my water pump.

[@ExtremeDIYGuy]

That's great! I'm glad the video helped. I tried to make it as informative as possibe!

[@scottyfixer452]

Did you do the blow test on yours

[@ExtremeDIYGuy]

@@scottyfixer452 Yep, no flow in one direction, a bit of a horn in the other

[@hawkofthenorth4829]

Dab a very small amount of petroleum jelly, which is gasoline soluble, on each end of the small spring and you will save yourself so many headaches. Cannot stress enough to take photos of the inlet and outlet port locations. I can see how much this would cause grief. I actually recorded on my camera disassembly and had to go back and watch it to align it up correctly. Good video BTW.

[@ExtremeDIYGuy]

That's a great tip! Yeah, the inlet and outlet ports are probably the biggest cause of failed re-assemblies. I tried my best to show and explain how they should be positioned. Hopefully it helps!

[@rwagoner56]

This was very helpful. Thanks. I made the mistake of opening my old one before I knew anything about the springs and diaphragms. Everything fell apart in my hands. Luckily I found your video. Thanks again.

[@bwanadon1359]

You are a life saver. On the metal plate mine did not have the "U" on it. I put the crown side up and it worked. The first time I did it I must have put the crown side down and the screw for the last piece (filter) would not thread (wouldn't reach). Re-did the whole thing watching your vid and viola. Excellent instructional vid. Thanks.

[@stephenbourdon9326]

The cardboard and nails idea is genius. I've got a problem where the hose is siphoning back to the tank if the motor is shut off for more than about 3 minutes. I think the ball on top of the spring is my problem. Thanks for breaking this down. In the next life you can scratch "being a teacher" off your list, you've mastered that in this life.

This is very helpful. I have an old Evinrude 6hp that gives me trouble with cold starting. I have gotten to the point that I suspect the fuel pump. Also, never use brake cleaner on anything plastic.

[@ExtremeDIYGuy]

Glad it helped

[@Rustycam1025]

Great video; Thanks! Just as a heads up....another issue with these pumps is sticking or damaged check valves. The check valves are in the thick plastic part that is not included in either the OMC or Sierra kits. I have done a enough of these rebuilds to be confident that I had everything assembled properly and it still would not work. I looked closely at the two check valves and saw that one of them was stuck. I soaked it in carb cleaner for a couple of hours and all was good. Something to consider if you rebuild and still have problems.

[@ExtremeDIYGuy]

Thanks for adding the additional information and contributing to the channel!

[@curtis3653]

Great video boss man! I tried once and lost the microscopic dome support piece in my garage so I brought the fuel pump up to the living room and used your cardboard trick it worked great! Finally found the dome support piece and put it all back together

Tip: After blowing in both ends, blow into intake again, but plug output with your finger. If air still flows, you have an improper gasket seal and fuel will leak. Fix before installing.

I have a fuel filter between the pump and the carb and I can see it runs out of gas when the fuel tank is below the motor but will run good when I elevate the tank above the motor. My compression is 100 psi on both cylinders so that's not the problem. I think I will take it apart and see if it is put together right. thanks

the new pump was put together right but it failed the blow test. [ no noise] also the outlet only had a pinhole so i drilled it out but it still did not make a noise. I had the old one that I pulled off and it was still good [made noise]. So the old one is working and the new one is not. thanks

After watching this video, I think it's easier to start from the cap, nit the base and just use the assembly screws instead of the nails. This allows the spring caps to be placed in the correct position and they aren't falling over as easily. Otherwise, it's a great video! Thank you.

I rebuilt mine with a OEM kit 2 yrs ago no problem except I noted the gasket for intake cover was a soft cork material witch I thought ok but it did work well and sealed. but the end of this season I took the boat out and the gasket like shrank or what ever and leaked fuel all over. I tried fiddling with it to get it to seal but only ended up in cracking the intake cover so I ordered the parts OEM but they sent me a hard cork gasket for the cover this time and now I`m real worried about being able to tighten the intake with out cracking it again. Got eeby geebys for bit so now I`m letting it set til spring to do the repair maybe I`ll be a bit more confident about the install.

I noticed that the few other videos didnt give enough detail.... That what i thought after watching the other videos. I have a new Pump, and a used one, both are leaking if i prime the Engine, think they are both not working right. During priming only the overflow of the Carb should leak. Or is OMC different there? Dont think so.

[@ExtremeDIYGuy]

Your pump should definitely not be leaking when priming the engine. Sounds like there's a problem with the pumps. Also, if the float is working right on the carb, fuel should be shut off when the bowl is full. I would be careful not to over prime the engine and stop when the bulb starts getting firm. Not sure if that helps but worth considering.

I'm glad this video helped! I don't have a video on that yet but plan on doing one early this summer.

Dude...you STILL didn't explain thetiny spring placement properly/well enough. I'm way engine savvy but you wander off and switch-up your explanation reasoning right at. Up til then it makes sense. You tell , why, EXACTLY...in each position we put it "here" or there. You 'splained it 1-1/2 times and then assumed we knew the logic. Don't misunderstand. I'm only pissed b/c I'm overdue to fix this stupid thing and SOOOO close! A 1000 kudos for a job well done, honest. Thank you. It's just that the tiny spring part got presumptive pretty fast. In one position it's near the outlet. In one position you associate it's position with the vent port...just a little disjointed IMHO. Not trying to be a dick. Best I've found so far...and thx again.

[@ExtremeDIYGuy]

I made the video because all the other ones I found weren't complete so wanted to do one that explained it a bit better. Here's a link to a page that might help you. bit.ly/3hvQL7n

[@antonmihai8231]

Hi, I have an 1997 Evinrude 8 Hp 2 stroke. I'm having trouble starting to cold. I also changed the piston rings (the cillinder compression was 80 psi) , the spark plugs, I cleaned its carburetor and it still doesn't start. It starts very very hard only with the shock pulled and the acceleration at maximum. After starting for the first time this way, the following starts are very easy. Can you advise me what to do? Thank you.

[@ExtremeDIYGuy]

I would check the choke to make sure that it is working correctly. If I'm not mistaken, you should have an electric choke system that squirts fuel into the engine to help with a cold start. If that is correct you need to check the red switch, there is a normal position for it. If it is in the normal position, you can move it to the manual start and then switch it back when it starts. If you have to do this, the primer assembly has probably failed. The normal position has the red switch facing the body, the manual position is facing the opposite. I have a video that describes this for a larger engine but the concept is the same. kzbin.info/www/bejne/nWmpdH99m6uhgJY Let me know how that goes.

[@antonmihai8231]

Thank you for answer :) Hi, the shock is mechanical, not electric. Is simple. Today I opened the carburetor (again) - I reduced the fuel level in the carburetor a little - the float had a small stroke before, I mounted it again and it does the same - it doesn't start. I also took off the spark plugs - and they were wet after the test. I checked the ignition system and it sparked.

[@cartermorey6116]

[@kevinl2192]

Small spring positioning: To be clear. What you mean is: IF the outlet nipple (outgoing hose hookup) is in the same quadrant/corner/exits from 1 of the two possible spring positions' corners, then the spring goes right there. If not in same corner then the spring goes in the next adjacent clockwise/counterclockwise spring position that you come to. Clockwise/counterclockwise is based on if you were pointing AT the fuel hose outlet nipple. And I think there's one more way to explain this with respect to that little vent as well. I kninda did this for me and for you and for everyone...cause I want to understand. I KNOW you want to help and sometimes, 3 different ways of thinking about gives the best answer. Calling for Peace with Jose. Thx again, my friend.

Thanks Kevin. I posted a link in your other comment that has a very clear explanation on where everything goes. Hopefully that will clear it up for anyone that needs it. Thanks again.

[@gunfisher4661]

It all depends on witch direction the outlet faces for the base of the build not all motors had the outlet facing the same way even though it was the same pump in each that is the only thing that really confuses most folks. But you have to make sure the metal base has the arrow on the tab facing up when mounted then you can go from there like I did.

Very nice thank you

Most welcome 😊

What did i do wrong if my pump is pumping air?

[@ExtremeDIYGuy]

It sounds like one of the gaskets failed or was put in wrong. I would disassemble and start over.

[@ronaldbeatty9423]

Where the big spring go?

[@ExtremeDIYGuy]

Right above the bottom membrane 6:59 in the video shows where.

[@dylanlysaght3052]

Can the outlets be reversed? I bought Carbman 18-7350 Fuel Pump Replacement for Johnson Evinrude Seahorse Outboard Motor 6hp and the fuel in and out nipples are the opposite orientation to the pump I took out..

[@ExtremeDIYGuy]

IT can be oriented in whatever direction you need it to be. Look at 9:00 on the video and it explains how to make sure the air dome spring is correctly located for the orientation you need the outlet to be in. Hope this helps.

@@ExtremeDIYGuy i was going to use longer fuel lines instead, but i might try this, thanks.

@@dylanlysaght3052 Your welcome, let us know how it goes!

[@dylanlysaght3052]

@@ExtremeDIYGuy I just followed this 12 times, no whistle noise and its easier to blow through the outlet than the intake. then I tried it in every orientation. No joy. I'm going to step away and try again tomorrow. I didn't test it before I took it apart either so don't know if its a dud..

AWESOME VIDEO..THE BOMB!!

[@ExtremeDIYGuy]

Thanks!

[@chadbosko8935]

Hi, just put new pump together was leaking thanks, am i seeing things or do u have the outlet up side down, mine is at the bottom, or doesn,t matter? Very hard to blow air through but does go and make sound does that sound ok or should it go through very easy. UPDATE: took it apart and put back together 6 or 7 times and I can't get any air flow through either one of the tubes can somebody tell me what's wrong

[@ExtremeDIYGuy]

I posted a link to copies of the manual on Leroys ramblings page. Might be helpful

[@chadbosko8935]

Thanks my friend i actually got the pump all together, did engine rebuild and it just started , your video did help to some extent, Thax.

[@scottyfixer452]

Do they all make this sound when you blow in them . I bought a new one and it doesn’t make the horn sound at all. I also put it on my engine and there is no fuel coming through the outlet

[@ExtremeDIYGuy]

I don't think so, it should blow freely in one direction and not at all in the other. Mine just happened to be a little bit musical lol

[@duncandmcgrath6290]

I was wondering why you didn’t use the base gasket?

[@ExtremeDIYGuy]

As I understand it, that gasket wasn't used on the older pumps and is optional when rebuilding. Probably should have put it in but opted not too since it did not have it originally.

Tha k you thank you thank you 🙏
