Have an 02 Ram 2500 that has had the in-tank lift pump "upgrade", and I want to prepare it to use centrifuged WMO with a separate tank in the bed. Probably have to mount a lift pump on the frame and upgrade since the fuel pressure is not impressive even now with diesel. Use a draw straw instead of that in-tank pump? Any experience pumping this for the VP44 pump? Looks like cooling is an issue with low lift pump pressures. Going to consider Fass and Airdog, but plan to call them for advice. Many are cutting the WMO with diesel or RUG to get the viscosity right. Stock truck with no performance upgrades planned. Want to do this right the first time. Thanks for your input!!!

 

I used to run WMO in my 1992 truck, but I used to dump it in the main tank, about 1 gallon per 30 gallon tankful.

I don't know that I would try running the VP44 on straight WMO. I would be concerned that the viscosity would be too heavy and cause problems. I'm certainly no authority on VP44 pumps though, so maybe it wouldn't be an issue.

 

I am going to use a centrifuge to clean the WMO. Looks like it cleans well and gets small particles out better than just filtration. Will look into getting it tested to be sure it is cleaned well. US FIltermaxx is the brand I am going with. So much to consider in this venture.....

 

Yep, I get that it'll be cleaned WMO, I still worry that the viscosity will be too thick.

Hopefully someone with VP44 knowledge will chime in on this one.

 

Hello... back when diesel was over $4/gallon, I did all the research on WMO and that of making my own bio-diesel. Actually went to a bio-diesel training class and manufacture of it.
I ran WMO, made bio-diesel and ran all variations it in my truck.
WMO - I could never get right and at best diluted it to 50/50 ratio w/diesel. The truck ran and smelled like burning oil (because it actually was). The WMO was centrifuged & filtered clean. Certain internal portions of the VP44 have very tight clearances and while the WMO would burn and run the truck, I was always worried about destroying the VP44 as it was not engineered or designed to burn WMO. While refined differently and designed to burn, the same goes for two-stroke oil.

WVO- Waste vegetable oil. I went to the manufacture and learned how to make bio-diesel. I ran it in the truck probably up to a level of 60/40. The WVO and refinement of it to bio-diesel has a cleaning effect on the internals of the fuel system from the tank to the injectors. You have to be careful running bio-diesel the first time as with the cleaning it does will clog up filters if used in full concentrate at the beginning. I tried and ran variations of refuged/filtered WVO but the supply I could find wasn't enough to make the refinement and process to convert it to bio-diesel worth while. While this sound all good and beneficial, again, the VP44 isn't engineered or designed to run this blended or fuel viscosity.

P-pump has less tolerances and could possibly run all of the other fuel types but I did not have a P-pump truck to test or run any of these fuel types.
VP44 pumps are around $1,000. With that said and if still going to pursue running WMO, WVO or some variation in between, you'd have to understand that with fuel other than diesel, you'd be taking a risk that the pump may fail even if all precautions of centrifuge, filtering, fuel psi monitoring, etc are monitored and taken. I don't know but is it worth the risk and at what point do you break even or get to the plus side of running this fuel type vs. just running pump diesel. I realize diesel is expensive and I'm paying about $5.50/gallon right now but I know I don't want to buy a VP44 either and choose to run pump diesel.
Hopefully this helps and weighs some of the options!

 

I agree with high bid.

I would not risk a VP-44 with WVO or WMO, unless I had free spare pumps. Even then I would keep the ratio well under 50%.

If you really want to run that sort of fuel, I would recommend looking into getting a P-7100 pump for your motor.
