Converting from VRO to premix

[spingley]

I have a 1986 Johnson 90 OB that has a bad fuel/VRO pump, would like to convert to premix, does anyone know what fuel pump would fit that I could order from iboats?

Re: Converting from VRO to premix

If the fuel pump part works and the oil side doesnt you can just disconnect the oil side and premix. Detailed instructions are on this board. Search for disconnect VRO.

Re: Converting from VRO to premix

Some VRO's have rebuild kits available, depending upon model.

I'm such a cheap s.o.b. that I would seriously consider rebuilding the airmotor side of that pump for far less than what another pump assy costs.

I purchased a new standard fuel pump for less than half price of a VRO rebuild kit. So I went with that especially considering that the original pump would still have 23 year old parts on the oil side as the rebuild kits only contain gas side parts.

Good choice. New pump should be a known quantity !!!

mbueker, you need to start a new post so your question does not get confused with the original poster's.

I ordered: 'Mallory Fuel Pump 9-35352' from iboats website, it crosses over to up to a 115HP if you look it up on evinrude website ' http://shop2.evinrude.com/ext/index.aspx?s1=ada6ca942dbe085188dd37c6c0a6c7da ', so should be plenty of pumping capacity. I just hope that the Mallory pumps are good quality/reliable.

I tried to find VRO/OMS replacement pumps (BRP items) on iboats, but couldn't. Only Sierra and aftermarket things. I'm trying to find a BRP 50047423 (VRO/OMS for three wire). If they're on the iboats site, I'd like to patronize the company!

iboats does not carry them, if you Google VRO pump you will find a couple sites that carry them.
