Let me know what you find out. Mine is plumbed such that oil is off of IP pull only and not on fuel pump. Has run fine for the last 2000 miles but seems a bit quirky lately. Runs fine on diesel

Hi Bob-

I'll let you know what I find out - the folks at GreaseCar said it is important that the WVO be pulled by the lift pump AND THEN the IP pump, otherwise you risk damage to the IP pump in the long run. Mine also runs fine on diesel, too - just not a ssmooth as it does when it is running on WVO! Amazing stuff, huh?!?!?

Veggie makes a world of difference though I've got mine tuned such that it runs almost as smooth on diesel as it does on WVO.

My TD will not get a conversion. I'm going strictly bioD on it because the tank in the main compartment is too tricky to set up. Would need to be insulated (or use external heating before going up to engin), and I already have a working reactor..etc. Just easier for me with this particular ride, no statement on running WVO. Still will swear by it.

Okay, nobody has done booster pump wars like me except the pro converters. Here's what I know.
There are 12v reciprocating pumps that suck on a rubber hose and push to a rubber hose. I have seen a AC EP 12S run motor oil abrasive flurry for a couple of years, but they don't make those anymore. AC pumps were designed to suck air.
The NAPA pump I bought was made by carter div. of Federal Mogul, It was designed to be cooled by the gasoline, I surmise, because I went through 3 of them in a month, the coil would burn out when the line was dry. I use them to prime gas out of the tank to the engine pump, and sucking air, the carter ones burn up. NAPA finally bought me an AirTex from another warehouse to get me out of the store. I don't have the Airtex number, but cross to an AC EP12S. I allegedly bought an Airtex from CarQuest jobber, number 8012S, but I have never installed that one and it doesn't say airtex on the box, so I don't know if it is the same. This is a 5PSI pump.
There is a rotary vane intank 12 VDC pump at 7 PSI made for the 76? Pinto or Thunderbird with turbocharged 4 cyl. I found it at NAPA by thumbing through the book. Normal in tank pumps run to 45 PSI and would not probably be good slamming fuel into a diesel injector pump. I had good luck with the carter rotary from NAPA, but that tank finally rotted out and I abandoned it. If your fuel is not squeaky clean, prefilter with a GoldenRod 495 filter sold at the TSC farm store for tractor fuel. They are 1 QT and should separate out a lot of trash before clogging up. Mine would trap 2" of tank rust before I drained it, no problem.

Well, I got the 350SD running on WVO yesterday by hitting the throttle when I switched over to WVO from diesel! It blipped a little, then continued to run beautifully. I took it out for a highway run - speeds up to about 95mph - for about 20-25 miles, and brought it back home. Tonight I started it up to drive to a gig (didn't run the A/C because of a separate cooling issue - will be resolved soon) and although I didn't attempt to run on WVO because I couldn't afford to futz with it and be late to the gig, it ran significantly better than usual on B20! Very smooth, lots of power, and virtually no shake at idle! I was so happy!! I just hope it stays that way!! Once I confirm that the GreaseCar system is plumbed properly and determine if I do in fact need a boost pump for the WVO, then I should be able to run on WVO regularly!

So, wish me luck! I'll update when the issues are resolved!

BlevinSax - did you find out anything about the lift pump?

I have a 240D that has started stuttering at high throttle and I'm thinking it is lack of fuel supply. I want to put a pump on the line, but am not sure which one to get. Any ideas?
