i just receintly replaced my factory diesel pump with a fass pump. i have the veggie conversion with its own tank and own veggie pump. the only mod to the factory system is the cv on the engine block.
-when i am traveling at 50mph and when i slow down the rpm's bottom out and the truck stalls
-i am using the veggie side right now because new fass pump isnt sucking from tank, the fuel pressure is at 80psi when truck dies
any suggestions would greatly help thank you
