Ok. Thank you
Doesn't make any sense why you don't have full pressure.
I bet it is something super simple but I can't put my finger on it.
You used an air hose at the same access point where you hooked up that external fuel pump and had 40psi on the fuel gauge meaning the FPR opened and bled off the rest back into the tank which you said you could hear but when you hook up a good fuel pump to that same spot you only get 5-8psi on the gauge?
I can't really see anything else than bad fuel pumps, use of wrong port on fuel pump, cavitating fuel pump due to not enough fuel in basket or low voltage making the pump spin too slowly.
