The injection pump cannot compensate for the viscosity and as such, pumps far less motor oil per stroke as compared to diesel. This is why multifuel engines on the M35 had a fuel density compensator. This device was calibrated for gasoline to diesel, this same calibration may allow for use of...

I use a Mity Vac hand vacuum pump with reservoir to prime diesel fuel systems. Do NOT pressurize the tank, that is a good way to increase its capacity. You can pull the fuel faster as you have a 14 PSI driving force, atmospheric pressure. I wouldn't put more than 10 PSI in a tank as these are...

Nearly all metals catalyze vegetable oil polymerization. That "boiled" term in linseed oil is usually replaced with a metal catalyst. Japan Drier is one such product, most types are cobalt (purple) or iron (red-orange). Lead has been used in the past, hence the lead-based paint issue. I...

Vegetable oil is a TOTALLY different chemical than any mineral oil. Vegetable oils and all biologic oils are triglycerides, esters in chemical terms. Meaning they are combinations of fatty acids and glycerine, a triple alcohol. The reactivity is still there, the fatty acids are aided by...

Filtering will not prevent damage with waste vegetable oil. Period. It will corrode and plug any fuel system, even those plated in 24 karat gold. The only way to use it in any fuel system is to convert it to biodiesel. Even then, it will still polymerize. Virgin vegetable oil will stick...

Don't use waste vegetable oil. It corrodes the system. Viton can be attacked by acidic waste vegetable oil. If you have a source of WVO, convert it to biodiesel.
