yeah well u get both types suck and push, personally i got myself a little inline pump which can be used as a lift pump or booster pump etc. even though its self priming / lifts fuel (sucks fuel) it isnt really designed to do it as its main function, as has been said its designed to push, so its best to mount it as close as possible to the tank and as much below as possible.
my pump, pierburg inline "3-7" psi was easy to put in and cost about $80 from supercheap. its loud when it primes but goes quiet after. it has a little regulator in the engine bay adjusted to 3.5psi. i think a good regulator would be a speco one for about $40. i think they are rising rate too.
it doesnt run a return which seems to be common, i am gonna hook one up though cos once my car was left on ignition and the pump died not surprisingly! or somehow connect the pump wires so it only runs when the car runs. i think the return is a good idea cos i see air in the fuel filter sometimes and a return should eliminate the air problem.
it was easy to mount being inline and used standard 1/4 inch fittings unlike other pumps which would have to be modifed to 1/4 inch. and it came with all brackets and mounting hardware/rubber vibration insulator. and self priming meant almost
no chance of dying. i think its a vane type. i have put a little inline fuel filter between the tank and the pump.
at the wreckers you can find some old small elec pumps - ie low pressure high volume in certain cars, like in early efi cars, but meh too much effort and time compared to a new one with all the bits included.
most of you know all this lol but it should be a good read anyway for other people
i'll get some pics of the setup if anyone wants em i'll email them.
