Outer Limits 4x4 Board

Im in the market for a fuel pump for a 16B, Im putting the motor in to a 1L
stockman.

Im going with an external pump but Ive just found this link thats thrown me.

I was just going to buy a pump off a skyline or VL commodore, I think they run at about 14psi. This thread says I have to run one thats capable of 45psi. Is this crap or are pumps rated differently or something?

heres the link

this guy doesnt really seem to know that much......

vl pumps run around 35psi, which is what i used for my jimny efi conversion.
should be able to pick them up for around 100 bucks.

im using a $80 special pump from repco , that pumps fuel to my surge tank, i have a 2L surge tank then a vl turbo pump to the fuel rail, works great it has never let me down.

Was the surge tank from another car or just a 3rd party one ? I've got a pump going from tank to rail so am looking at adding a surge tank as well.

nah bought the surge tank off ebay for $100, i was told to use one as otherwise u motor may die in the arse up hills because it needs its constant pressure to keep it running, so i thought it was a wise investment, plus its polished and it looks quite pretty in my engine bay

You dont need to run a surge tank but IMO it is a good idea because it is hard to keep fuel to the suction side of the pump when cornering & off camber, especially when the tank is starting to get low. These EFI pumps do not like sucking air & it will kill them quicker.
