Pulling WVO System From My Bus

I bought a bus that has a WVO system installed, and I'm looking to remove it - How much work should I expect? It's in a 1994 7.3IDI, and I will be home-basing in an area that rarely gets above freezing in the winter.

Is there a market for used WVO systems? I'll probably keep the tank as a greywater tank.

If you think this is an awful idea and I should keep the system, convince me?

The only folks I have ever chatted with WVO systems were either super Green and convinced themselves they were saving the planet...or had tried it and found it to be way too much of a hassle. Might be OK if you lived near a source and didn't travel much, but I have heard more DISenchantment than positive feedback. Maybe someone else here knows otherwise but it never interested me.

As for pulling it and going back to a standard fuel delivery system, it sounds like a fair amount of work, but certainly doable.

I'm thinking that the upkeep will be a lot of work for the benefit that it will provide. The diesel system needs some love, so I think with the overhaul I can pull it out at the same time.

There's a good chance that you could just leave the tank and use it for additional diesel...

Yea why go to the trouble of pulling all the stuff out when it's perfectly usable as a reserve fuel system? Just take the stuff that's WVO specific out, and replace the filters with fresh fuel filters.

When the greasecar forum was really active years back, the regulars had a well used saying--"greasing-it ain't for everybody." Ok your call. Taking everything off is fairly easy. If there is a seperate tank, that system runs seperately from the stock fuel system. Do some hose tracing-you have diesel inlet hose + a return hose. They will each have a solenoid inline. When there is no power to them, they default to flowing diesel. Look for the in+ out line on the pump--and back to the tank. Bypass the solenoids + the fuel system is back to stock. And any water lines are just tied into the heater hoses. Take out any Tee's + thats corrected.
I know alot of people in your area-but the only grease guys I can think of are down in Randolph.

I don't think it's for me. I tinkered and traced today, and it seems to be a relatively simple system without the wvo.

If you know someone who might want a pre-turbo Ford 6.9/7.3 wvo system (minus the tank), let me know! I'll probably pull it off tomorrow or early this week. Randolph isn't too far.

I'll leave the tank, but use it for grey water. Its downhill and already installed.

I'm all for redundancy, but having 75+ gallons of diesel on board seems excessive for my intentions.

If your not using it for grease just yank it out. Your always messing with them. Heating diesel is a pain in itself. The only benefit is just using it as a unheated system and having a extra tank. If your range or want isn't that far just take it out. Its a love for teh system that keeps them alive that why you see so many WVo systems not running any more. They lost there love for them after about the 100th time they failed them some how.

I can tell you when your at the fuel pump the guy that does not mind buying the diesel at all is a ex fryer buyer.

Craigslist the whole thing after its out. some one that has never used a system before is always ready to create the perfect system. Dont get in the way of there dream.
