Ok, i have never really had to do this before, so i am not 100% certain on EXACTLY what should be done.
The fuel setup to be thus far is:
# standard tank
# AUDI/PORCHSE Bosch 921 high pressure pump
# lift pump (not sure on specs)
# surge tank
# standard fuel lines
Now the way i think i'm supposed to set this up is:
# From fuel tank to carby fuel filter
# carby fuel filter to lift pump
# lift pump to surge tank
# surge tank to EFI pump
# EFI pump to fuel rail (along standard feed line)
# Fuel rail to return line
# return line as standard back to the tank.
HOWEVER!!
Some people have mentioned that the lift pump won't flow enough to keep the surge tank full or something like that, so the surge tank needs to have a return back to the tank, or something like this?
I have a 3rd (currently blocked) outlet on the surge tank which i can use as a return, so i just want to know what i should be doing. Thanks
