93 F250 7.3 idi on WVO
I'm having some issues with my veg conversion :
I'm using a two tank system, heated fuel pickup, in line prefilter, heated veg filter under the hood, and FPHE. I'm using a new stock mechanical lift pump for both fuels, which most people say works just fine. But - when i open the air bleed valve on my veg filter, a lot of air is apparent, and eventually after about 45 minutes of highway driving, the truck will stall due to all the air in the system. Runs fine on diesel. Any advice?
Today i tried connecting the lift pump directly to a bucket of clean veg, but the same amount of air is seen when we open the air bleed valve on the veg filter. Both filters are new and clean, veg is settled then filtered to 1 micron.
