I have NEVER had any issues with the Aeromotive Marine Grade fuel pump in my truck.
Hell, I even sold it to Josh Davis after using it for about 6 months...he never used it...I went through 3 FASS motors, and then bought it back from Josh, and have been using it ever since with no issues.
#1 Rule: use a sump.
#2 Rule: use a good pre filter, like a DAHL-200 (that's what I use)
#3 Rule: use a post filter after the pump. (I use an Areomotive 10 micron attached directly to the pump.)
#4 Rule: use at least -8 or -10 line from the pump to the front of the engine bay.
#5 Rule: use a "Y" block for splitting the fuel flow to both sides of the heads.
#6 Rule: use -6 line to the front of the heads, and from the back of the heads to the regulator. (I use an Aeromotive Marine Grade regulator set at 65 psi, with no boost reference)
#7 Rule: run the return line through a fuel cooler. (I have a huge fuel cooler mounted in front of the intercooler.)
#8 Rule: Use a check valve in the return line to the tank.This will prevent the fuel from siphoning back to the tank.
This is the way my setup is...take it or leave it, I don't much care. I have tried several different methods of building my own fuel rails, and such...but the way I have it now has been flawless.
Common sense applies when wiring up pumps as well...proper sized fuses, wire gauge and relays...
