vro conversion how to convert your vro fuel pump to a standard fuel pump

[@mikepraed4623]

Thanks for making this video. I'm getting ready to convert my 90 Johnson.

[@fghhhgdfgdf]

Thanks for this quick vid. Was to the point. Helped me convert my Johnson 60 in less than a half hour.

[@DeHavenRanch]

Thanks for sharing! Saved me from buying a $600 VRO pump and blocking it off!

[@richardbarber2716]

Thank you, working to fix someone else's conversation and they had the hoses wrong. Great video.

[@mattfordsgoatfarmingtips1646]

Thank you, and glad to have helped.

[@toddmaki2959]

Doing this right now and needed to know this information. Thanks for posting this video!

[@iroc2019]

When you disconnect the vro there should be the three hoses you mentioned. Remove the oil hose

[@alafanlaman]

Thanks Matt. Great video. There are a lot of duel pump set-ups out there but I do see that you are running a single pump set up on an Evinrude V-6. I am planning on converting to a Johnson V-4 120 Looper engine. Was worried that it would not be able to keep up with fuel demand but it looks like yours works very well. Appreciate you taking the time to do this.

[@mattfordsgoatfarmingtips1646]

Glad to share, and good luck with your projects.

[@stevogoalie20]

Thank you! Tackling this project very soon. 🤞🏽

[@jimsutton5691]

For any asking...if you get the pump with the port in the back, AND the nipple for vacuum....I did have to put a gasket behind a plate to close off the rear port...without that I don't think the pulse will work

[@skeeterjeff2012]

This pump has a nipple that hooks to the vacuum, not a port.

[@reliks14]

Thank you for commenting I just asked about this I was like all the videos I see no one is mentioning this lol

[@600bom]

samething just happen to me order the same pump but there a hole in the back and when i turn de key the fuel coming out from there

[@anniers6882]

Amazing video , I just bought one without the the VRO PUMP so there was just the hoses disconnected but I’m having problems witch hose is the vaccum line , is there any way you can show me where is coming from

[@juanantoniorubio805]

Exactly what I was looking for! Thanks!

[@garybryant8879]

Good job! Thinking about deleting myVRO on my 50 Johnson. Not sure whether to continue using the vro for the gas or get a gas fuel pump.

[@harveyfloyd6045]

Did the fuel pump keep up at WOT?

[@laytonneal4836]

Wow I feel like I could be a boat mechanic now This is so empowering

[@mattfordsgoatfarmingtips1646]

Glad to hear it and thanks for watching.

[@sylviamiddlebrooks26]

Were the vacuum line connections to. Can you please let me see the only in. We're the vacuum line ends. Thanks you

[@skeeterjeff2012]

The vacuum line connects to the block, in the original configuration of two pumps. They mount right to the block, no ports to cover. The vacuum port was plugged in the vro motors, but easily unscrews so a brass hose barb can be threaded in. Guys one pump is not enough for these crossflow outboards.

[@reliks14]

So you just block off that vacuum hole on the back with that bracket? Or?

[@25682allen]

What do I do with hole in back of pump?

[@John-o1m5m]

I don't know where you're getting your fuel pumps, but the last two I ordered both leaked.

[@mattfordsgoatfarmingtips1646]

I linked the one I purchased in the description of this video. Just scroll down as your watching and click more in the description area and the link to the fuel pump I have is there. I have had no trouble. Best of luck.

[@timesthree5757]

Rebuild a 1976 115hp Johnson was wondering about this. Thanks.

[@skeeterjeff2012]

The 115 would use only one of these pumps.

[@timesthree5757]

@@skeeterjeff2012 yea I figured that out.

[@CTRadventures]

Those are all 3/8 right

[@Alejandro.Gonzalez245]

I installed a clear hose on the fuel outlet I saw little supply of gasoline and it did not mix oil, the gasoline did not look blue. I saw your video on how it works with a simple pump and I was convinced to go for the change. I don't know since when I've been running low on oil that worries me . Does the pulse limiter valve need to be removed?

[@brandonterrell1838]

We changed over to the fuel pump, but the carbs are loading up and gas is pouring out of the foot. Any suggestions?

[@ericurrutia1714]

Do you use One or two for 200hp?

[@skeeterjeff2012]

You do need two of those style pumps, just like the 1983 and earlier V6 crossflows. You will burn that motor up trying to run on one pump.

[@derekmcdougal262]

I have 2 on my 1991 150xp just took both off went with a electric pump that supplys enough

[@ggw7948]

Holley blue fuel pump or mr gasket with regulator. Keep your psi set 9 or below to keep from pushing fuel through the float needles. 6 to 8 psi is the sweet spot for a 200 to 250 hp.

[@derekmcdougal262]

@@ggw7948 first person I have actually come across that knows the answer of how much psi will push by the needle thank you for this reply

​@derek mcdougal I have a 150xp as well. would you be so kind as to provide a link or model of the electric unit? Also does the unit stay below 8 or 9 psi?

1991 Evinrude TE60TLEIB training to bypass my oil injection pump and go pre mix will this work for this motor

[@mattfordsgoatfarmingtips1646]

Should work fine, but just research what ratio you need to premix at. My 1988 150hp outboard requires 50:1 ratio mix.

[@jacklowe3788]

Did you convert your motor? I have 1997 60degree V6 motor I was wondering the same- Few years back I read where someone was using some sort of 2 pump configuration but sure would like to keep simpler if possible- This motor only has 90 original hours but has been in storage for 17 years- kinda afraid of running after been sitting so long-

[@jeffpopp7591]

❤ very helpful thank you

[@brandone6252]

What’s the part number thank you

[@amtplumbingandexcavation633]

Why did you do it? I have a four cylinder. It’s running like crap. I’ve tried everything else but the fuel pump.

[@texasstarauto4542]

What fuel mix do you use. And the ratio?

[@mattfordsgoatfarmingtips1646]

Premium non-ethanol gas, and the ratio is 50:1. I hope this helps, and good luck with your projects.

[@ericparker6317]

Do you need a vacuum line?

[@mattfordsgoatfarmingtips1646]

Hi Eric, the vacuum line is needed to power the fuel pump, so it is essential for the fuel pump to work. Thanks, and best of luck with your project.

[@scottpavelka2977]

Great video. Just curious if you have a fuel filter assembly hooked up and connected to one of the fuel lines that connects to your replaced pump.

[@mattfordsgoatfarmingtips1646]

No, I did not add an inline filter, but could be done if it doesn't slow down the feed rate for the fuel.

[@fghhhgdfgdf]

@@mattfordsgoatfarmingtips1646 I added a filter. No flow issue at all. May want to think about it as the old filter i pulled out with the vro pump was gross.

[@tylerratliff703]

I’m doing mines right now, so all I need is one standard punp? I have a 86 evinrude XP 150?

That's all you need. I've been running this setup for two years with no issues.

[@tylerratliff703]

@@mattfordsgoatfarmingtips1646 Thank you!

[@ColtenBethel]

Thank you, this helped out a lot!

[@timwendling5773]

Do you plug the hole in the back or leave it open

[@mattfordsgoatfarmingtips1646]

I believe that the only thing you have to plug off is the oil line. The lines you should have now is fuel line, vacuum line, and the fuel out. The fuel line should be bringing in premixed fuel 50:1 for my Evinrude. Hope this helps and if not share a picture of the issue.

[@toyman81]

What did you do with the 4th line that was on top of your VRO Pump?

[@treyzapata8481]

That’s the fuel outlet line it goes on the bottom of the new fuel pump

[@big-n-bama48]

Have you put it under load yet.. Wanting to change my 92 150hp over but keep seeing on some sites that 2 reg pumps would be needed to feed the 6 carbs..I don't think this is mandatory..Thats why I'm asking you, who has done it to a V6 already.. Thanx "RTR"

[@mattfordsgoatfarmingtips1646]

My boat is an 18ft bass boat and has a 150HP V6 and it runs good with just one of the little standard fuel pumps. I have driven my boat since the conversion and it takes off good and will go 55MPH no problem. You will want to make sure you have a good vacuum line when you do the conversion, otherwise it will run run up to about 30MPH and then the vacuum line will collapse. I spliced a piece of vacuum line on to what was there when I did the conversion originally and it would shut down if I ran over 30MPH. I now have a brand new piece of vacuum line ran to the new fuel pump and it runs great. The parts diagram for the V6 on the 1982 model before the VRO fuel pump was implemented, shows using 2 of the little standard fuel pumps. I decided to try just using 1 fuel pump on my 150HP outboard and it works fine for me. Good luck with your projects and hope this helps.

[@alafanlaman]

@@mattfordsgoatfarmingtips1646 Great tip. Plan on replacing all fuel and vacumme lines.

[@Table1000]

@@mattfordsgoatfarmingtips1646 Man! Thank you for mentioning the vaccum line issue!

[@skeeterjeff2012]

Yes you will need two of these fuel pumps. This guy will burn his motor with only one pump. It will run all day on a hose with one pump but when you put a load on it it will not last long.

[@phillipwashington8941]

Thanks a lot good work

[@kellie3363]

Thanks for video how’s your pump holding up? I’m doing mine right now

[@mattfordsgoatfarmingtips1646]

Two years later and still going strong.

[@americafirst9945]

Would this pump be sufficient on a 1997 Johnson 115hp looper? I been reading the loopers creat less vacuum

[@shanebarrett5827]

How’s the boat been doing on a single pump? Plan to do mine soon if it’s working good.

[@mattfordsgoatfarmingtips1646]

I am pretty proud to say that it runs good with just one of the little standard fuel pumps. Hope this works out as well for you as it has for me.

[@shanebarrett5827]

Did your motor have a vapor separator tank or just a vro oil/fuel pump straight to the carburetors. Mine is a 2004 Johnson with the vro, vapor separator tank and pump, and prime solenoid. I was planing on deleting all and just go pulse fuel pump straight to carbs with prime solenoid on a tee.

[@mattfordsgoatfarmingtips1646]

@@shanebarrett5827 I believe my setup is very simply a fuel line from the fuel tank with an inline primer bulb that carries 50:1 mixed gas to the carbs. The only thing I can think to tell you is try what you mentioned and if it doesn't work go to a simple setup like mine. Good luck with your project and hope this was helpful.

[@mtnpwr]

Did you end up running the main fuel out to the manifold “splitter” to feed fuel to the carbs?

[@mattfordsgoatfarmingtips1646]

That sounds right the VRO hooked up to one place and feed all three carbs. So, this is where your fuel out from the standard fuel pump needs to connect. Hope this helped and good luck with your project.

[@mtnpwr]

Thanks!

[@toyman81]

I have 4 hoses going to my 1989 Evinrude 150XP VRO Pump, 3 in the bottom and 1 at the top. The Replacement fuel pump only has 3 hose hookups. Is it alright to just plug up the top hose?

[@mattfordsgoatfarmingtips1646]

The VRO fuel pump has 4 hoses that connect to it one of which is an oil line that comes in from the front of the motor. In switching to the standard fuel pump you need to plug the oil line off, and this will leave you with only three lines the vacuum, the fuel in, and the fuel out. I point out which ports are vacuum, fuel in, and fuel out on the video for the standard fuel pump. After you do the conversion you will need to mix your own gas I mix mine 50:1 for my 1988 150 Evinrude. Hope this helps and good luck with your project.

[@richmel6245]

So, by doing this change over, you need to have to do the oil/gas yourself?

[@mattfordsgoatfarmingtips1646]

Yes, that's correct.

[@jareddouglas37]

Appreciate!

[@hehoggs8131]

Why would you just not rebuild the vro pump . I believe the last one I did cost like 20 dollars

[@mattfordsgoatfarmingtips1646]

The VRO I replaced was freshly rebuilt, and so I did this on the hopes it would last longer. I have been going for two years after the conversion with no problem. Thanks,

[@Real.Alpheus]

Heaven forbid you could have used the camera to zoom in on the pump without having your face constantly in the shot.

[@mwgrc]

If you guys would just read the service manual and do the required maintenance and system checks on your Outboards all these deleting parts videos wouldn't be necessary. VRO's were and still are a step forward, why you guys want to spend a bunch of money to go backwards is beyond me, but carry on.

[@jonsoucy3042]

Vro system parts cost 10x as much.. I have a 1989 and naturally materials break down. So the diaphragms have failed....I looked up the replacements and just the diaphragms cost around $200. I can buy a 438559 pump for just $20 and fix the problem.. Not to mention it's faster to make the swap than it is to rebuild the vro

[@Holler_Rat]

Complexity is the enemy of reliability. A VRO is great in theory, but I don't want to buy a new engine because a 10 cent diaphragm fails.

[@jayhavey1170]

Proper maintenance is not a factor old Parts crack and fail and I believe I have the better ability to mix the proper amount of oil without the worry of a failing pump

[@mwgrc]

@@jayhavey1170 It’s Obvious that none of you guys that are commenting have even read the service manual. Your statement sounds logical, but had you read the manual you would know that can’t happen if you follow the procedures. But I digress I should not have ever commented as to each his own, some embrace technology and some don’t. So mix away 👍🏻
