Anybody know which engine has a better reputation for a WVO conversion, the later Powerstrokes (7.3/6.0) or the 5.9 Cummins? I know the Cummins has a better rep as far as buring old #2, but does its reliability hold for WVO?

Thanks,
Brent B.

Truck has 170,000 miles. Just spent 1K on new interior. 1 year old transmission. great candidate for wvo conversion. 12v cummins. $10,000 Truck is located in Long Island, NY please email only to 1badevo@verizon.net

Great to have this - thanks very much!

I have a 2003 Dodge Ram, 24V, 5.9L Cummins that was in January ’07 converted to run on straight vegetable oil (VO). The stock fuel system in the Cummins engine has the lift pump mounted on the fuel filter, i.e., NOT in the fuel tank. In my VO conversion system I have an MSD lift pump, (model # PN 2225, rated at 43 gph @ 40 psi, 5.4 amps [gasoline rating]) with a pressure regulator on the discharge of the MSD lift pump to regulate the VO pressure down to 6 to 9 psi, in the range that the injection pump likes to see. My MSD lift pump recently failed. I am in search of a new cost-effective lift pump to replace my failed MSD lift pump. I have to questions – (1) what would be a good readily available lift pump to use, make and model number, that is not too expensive, i.e., less than about $150 and (2) did I need to use a pressure regulator in the discharge of the MSD lift pump and will I need to use a pressure regulator in the discharge of my new lift pump?

I recently began running my '98.5 Dodge Ram, Cummins 24V on WVO. Now, I have not done any sort of conversion, although my truck is equipped with a fuel heater. I am noticing that the oil may still be a bit too thick for my fuel system, so I got to thinking about cutting it with another fuel for easier flow. Now, the obvious choice is kerosene, and I do at present have a pretty hefty supply of it. However, I if at some point I run out and replacing my stash does not look to be as cheap as I would like, i came to think that a small amount of gasoline may be a suitable replacement. Now I know you are all thinking that putting gasoline in a diesel is a bad idea, but if it were mixed in small quantities (which is more feasible than kerosene, as it is a better solvent, and would allow a higher grease/thinner ratio) its speedy burning should be slowed by its dilution. Plus I think the highly flammable nature of gas might help for a more complete and cleaner burn of the oil. Any thoughts?
