Fuel Pump
Re: Fuel Pump
oh im pretty sure all third gen fuel pumps were intank pumps (inside of ur fuel tank, thats why you can not see it) but i guess maybe some carbed ones came with mechanical pumps (mounted on the side of ur block, runs off a cam lobe) but im not 100 percent on that, chances are its inside of your fuel tank.
Re: Fuel Pump
my 87 iroc, has a 305 carb, mechanical fuel pump on side of block
i know all the carbed small blocks have mechanical fuel pumps
i know all tuned port, and v6's have intank pumps
i dont know if the mechanical fuel pumps provides enough fuel pressure for throttle body or crossfire systems, probably not, so those probably have intank pumps as well

Re: Fuel Pump
well turn the key to the on possition. If its an intank pump it will prime for a few seconds and youll see gas poor out of the feed line (put a bottle on the end please, and no cigarettes no matter how bad you fiend).
Re: Fuel Pump
I don't remember exact pressure numbers, but TBI intank pumps were weaker than TPI intank pumps. If the motor you are installing will require some decent fuel pressure, just buy a nice walbro or something and install a regulator.

If you are installing an FI - install an in-tank pump, or you can run one "in line" and mounted to the underside of the car. If you are running a carb, then the block mounted mechanical is the way to go.
