Fuel system is fixed...
first i made a fitting off the front of the pump for fuel pressure, off the allen plug that people use to dual feed trucks. I welded a male #4 fitting on the end. fuel pressure was instantly down to 0 with any load on the truck.
then took and changed the filters, the primary was full of rust, but it didn't make the truck run any better
then went and put 120$ of fuel in the tank, thinking the 4 gal I had in the tank was probably flowing to the back of the tank... no dice there either.
....then I threw a spare FASS pump on the truck from a VP44 truck, the type with no fuel filters.
still ran like garbage.
finally pulled the piston lift pump off again and realized that I tapped the check valve on the outlet of the pump on too far. Looking at the checkvalve and the way the outlet is setup one would imagine that it pressed all the way in.... nope.
anyway... now ive got about 65psi of pressure revving the truck in neutral, and 25 psi full bore with the dually's spinning in 4th
my biggest question is now... why the hell is the truck still clearing up all the fuel?
so I'm at 45pi of inlet fuel pressure normally, the afc is tuned for full travel, and slid all the way forward. its got a rack plug, no plate, 4k's set at about 4 clicks, and 5x16's.
air side is a steed comp, and the 62/68/.84 T4
I feel like there is more fuel there than what this little 62 is burning....
dynoing this saturday, hoping for 525 or better.
