How to Remove and Replace a Johnson or Evinrude VRO oil Pump with a Direct Fuel Pump

There's a lot of videos that describe how to disable a VRO2 unit. Here's how to go a step further and completely remove the VRO2 unit and replace it with a fuel pump. Link is below for parts list. You'll have to pre-mix your fuel after disabling or removing the VRO2 unit, but it's worth it in my opinion. You'll have the peace of mind knowing that your outboard is getting the lubricant it needs!

I really appreciate this video. I have removed my VRO pump and replacing with the standard pump. I couldn't figure out what to do with the line coming out of the block, until I saw your video. I will plug it up and complete my project tonight and see how she runs.

Thanks Ricky, I appreciate the positive feedback. I'm glad it was helpful. Let me know how ot goes when you fire it up again!

I just acquired a boat with an Evinrude V4 120 with the VRO setup and should I run into problems, this video will help me convert to just the pump. Great job on the custom manifold and love the colored racing fuel lines!

Thanks, I'm glad it's helpful! I couldn't just go stock with the fuel lines LOL!

[@rodmauldin]

Hey thanks for the video! I have an'89 Johnson 110 and had to have a new power head put on because the VRO was over oiling and eventually caused so much carbon lifting of the rings it ruined the previous power head. Also had Marina put a standard fuel pump on so I could just premix. Anyways the engine has never ran smoothly since the new power head.I figured my Carbs needed rebuilding as they leak down real bad when tilting engine. So today after taking the carbs off the intake I see a hose connected to the block / intake that isn't connected to anything else. Yep just laying there hidden under the bottom carb sucking air into the block! I immediately assumed it was a pulse source for the old VRO pump but it was hard to tell by parts drawings. Your video confirmed my hunch. My idle has been terrible since the new power head and fuel pump conversion and I now think this is the culprit along with the old leaking gaskets on the carbs. So hopefully when my carb rebuild kits come in, I will have good news to report. I'm probably going to just plug off he pulse hose like you did. Thanks again!

[@ExtremeDIYGuy]

Wow, yeah running the enigine with that port open is going to create a lean condition for just that cylinder! Hopefully once you get the carbs back on an plug that hose it will run great. I also have two video on the carb rebuild if that helps, kzbin.info/www/bejne/q4CvqK1og7-Gg7c is the first one and kzbin.info/www/bejne/jZPKfYKHi7-BftU is the second one for the idle jet

My Evinrude/Johnson OEM fuel pump came without the gasket or bolts, so had to order them. The bolts are 10-24 1 3/4 stainless pan head. The gasket is pretty specific, so if you are going to order it, you might as well order the bolts as well.

I'm not 100% sure of what you are describing but I don't think it will work. There is no way that I know of to attach the impulse line hose (from the original pump) to a replacement pump, unless it's another VRO pump that takes the impulse through a hose. I hope that helped.

[@zainkamoi]

Hi, Excellent and informative video. I have a 50Hp Johnson (-93 I think) with external oil reservoir. So the VRO is a bit more complex where oil and fuel gets mixed in the VRO. I plan to do the replacement of the VRO when winter comes. I see there are two types of fuel pumps available, three nipple and two nipple pumps, yours is a two nipple version it seems. Could it bee that the three nipple pump actually is an oil/fuel mixing fuel pump? Do you mix oil into the fuel tank yourself (ratio 50:1 i think is correct) or do you have an external reservoir as I do? Thought I should ask since the video did not mention it. I actually think that mixing the oil and fuel into the same tank would remove a lot of worries as I may remove several sources for error and simplifying the whole system. Only concern I have with that is that my VRO have a small PCB with sensors sensing oil flow, and a three wires connecting it to the main board. I need to find a way to bypass this, probably by just connecting the sens-wire to pos or neg terminal, so that the engine doesn't get shut down due to "oil flow" failure..

[@ExtremeDIYGuy]

I'll try to answer as best I can, the pump you mention with 3 ports does not do the mixing, the third port is for the impulse hose that was originally on the VRO unit. That 3 port pump is actually designed to replace the VRO pump and use the same bracket the VRO was on but IT DOES NOT mix the oil for you. YOu have to mix the oil your self at a 50:1 ration if you remove the VRO unit. There is a wire that needs to be disconnected on the VRO and that will disable the alarm feature.

[@anniers6882]

I just purchase a 1984 Envirude 185 Hp and there was not fuel either the vro or the conversion one so I’m trying to know witch lines go where, I have 2 entrances in the block should I use one pulse line and close the other one ? , in this case Im trying to install the same pump you use but the 3 hoses connections

This video was very informative. I have a 50 hp evinrude. Do I have to replace vro if I just disconnect the vro? Will the vro still pump fuel if I mix it myself. Or is it just best to do this complete fuel pump swap to ease my mind

Most folks just disable the VRO and run the fuel pump in it. I went ahead and took it out altogether although it's not really necessary. I looked at it as one less complex part to break down!

Just wrapped it up in tape and tucked out out of the way.

[@JoshRMalone]

@@ExtremeDIYGuy Thanks! I also wanted to mention in case you are still having "a miss" like you mentioned in other comments, you might try removing the fuel filter since the new pump actually has a built in screen filter (per schematics) unlike the VRO2. So you might be restricting flow with double filter. Mine is a 1988 Evinrude (I believe that is what you said yours was). That said, double check! You probably already knew that and know more than I do, but figured I'd pass it along.

I agree that ethanol can definitely gum things up. I've also heard that rebuilt VRO's dont work right more often than not.

Him not a bother at all. The Fuel pump for this engine is OMC # 0438556, it does not come with a gasket which is part # 0303615. I would go with an aftermarket part as there is a significant cost difference. As far as the engine head, there is usually a small circular plate on top of the block about the size of a quarter. The markings on that may help identify the engine. The best place to find part numbers is www.marineengine.com. I buy parts from them as well.

What's the correct fuel oil mix

[@ExtremeDIYGuy]

I used 40:1 but really depends on the engine.

How did it proform?

[@ExtremeDIYGuy]

It performed well. Perhaps a bit better but hard to tell with an older outboard.

@@ExtremeDIYGuy did you have to alter any throttle/fuel/idle settings..?! Mine now seems to cough and splutter and only seems to run continuously by pushing in the key to activate the primer solenoid. Lots of smoke, ha ha..

[@ewanbaxter9199]

You don't have to mount it on the engine though. It is easier by far if you mount it on a flat plate in place of the VRO and no need to plug the impulse hose because it is used..

[@callmesceptical9114]

Huh? Of course you need to plug the impulse hose, and of course you need to mount the pump to impulse port. ✌️

[@maxhiltin1133]

The 3 nipple sure, the two nipple you absolutely have to mount it exactly as video states..

@10:10 in case you don't know how to pronounce edelbrock, just remember it rhymes with needlecock lol

[@ExtremeDIYGuy]

Lol, thanks! The funny thing is I knew that. Been a fan of Edelbrock since I was a teen. I suppose I was cam scared or something. That's my excuse and I'm sticking to it.
