Rebuilding VRO

My mechanic says the fuel pump has gone, so I'm looking at an attempt to try to rebuild the VRO.From what I've read warped housings seem to be an issue.Is it worth trying to rebuild since the kit will run 100.00 or should I just spring for a new pump?. I'm premixing fuel ,oil so I really don't need the VRO , but my mech didn't mention a reg fuel pump for my engine.He said something about the holes being there, but it seemed like it couldn't be done.
It's a mid 80's evinrude 150 v6.
I'd be doing the rebuild so any tips would be helpful.
 
if your premixing, you should buy the fuel-only pump, although several on here have successfully disabled the oil side by unplugging the harness and capping the inlet.

I wouldn't try to rebuild it, and if you're buying a new one, it may as well be the one that's suited for your application. Cheaper, anyway.
 
When my fuel pump went I did away with the VRO entirely. My engine guy recommended going that route as he said VRO's give him alot of rebuild work. The downside is that my engine runs a little rich at idle but cleans right up once I get underway.
 
I'm one of the guys that runs a disabled VRO pump. It's not hard to do and it works perfectly. I like premix... a little more costly in oil, but much less expensive than a new engine. I don't know if it will fit your engine, but my original VRO had a bad diaphram but the housing was fine. I still have it if you want it. Send me a PM with your address and I'll ship it out to you. It's from a 1991 Johnson 200.
 
I run a Yamaha 2003, 200 HDPI, no worries here :beer ran a oil injection only one time before now and motor went BOOM!!: if this one ever gives me crap it will be back to premix so fast no one would ever no it wasn't! I have had alot of motors over the years and i not worried about premixing!!

YAMAHA's oil injection is about as good as it gets, but your HPDI MUST have oil injection to get ANY oil to the bearings. The HPDI injects the fuel directly into the combustion chamber, so no fuel passes through the engine. If no fuel goes through, than no oil would get to it with premixing. OPTI's, HPDI's, FICHT's, ETEC's, and any other direct injected 2 stroke engine MUST have oil injection to get oil.
 
Thanks for the offers guys,I'll keep it in mind if I run into problems.
I've been good with the disabled vro till this season.I took it off today and found that the vac hose that drives the pump was barely on, it was jiggling when you touch it.There was no way to get to it without removing the vro,so I guess it had to be done anyway.
I think I'm going to try the rebuild anyway since they recommend servicing every 10 years anyway.I took it apart and put it back together pretty quick, just for kicks.I'm getting the kits tomorrow and will see how it works when done.
As for the fuel pump only I'd need to get a lower and upper pump and figure a way to squeeze it all in there.
