ok, i need to move my fuel tank inside the cab as the axle is goin to get very friendly with it if i leave it in it's current spot.
i've thought about simply moving my tank inside the cab, but its already been punctured and repaired once, and i'm havin trouble finding a decent condition vitara tank.
so thinking about going with something like a fuel cell, or aluminium tank, with an external pump. but this is where i need advice.
my motor is the g16b, so i assume it'll need a pretty high pressure pump to run the efi. what sorta psi pump would i need? any recommendations? also, would i need to run a surge tank?
i know fark all bout efi fuel setups, so any advice would be appreciated
I would recommend running a surge tank for piece of mind if nothing else.
I got one for $75 from On track in brissy.
Also, IMO the best off the shelf EFI pump for motors under 3L or 200kw ( which ever is higher) you cant go past a bosch VL turbo EFI pump. Make sure you get the external one. I can get them from Ripco for abouy $160 ( RRP is $260 )
Depends on if you are running EFI or not. The surge tank is filled by a low pressure pump from the main tank, and then the high pressure pump draws from the surge tank to the motor. The idea of the surge tanks is to ensure that there is always fuel available for the high pressure pump to feed to the motor. While your driving, esp 4 wheeling, the fuel sloshes around heaps, and if it all moved away from the pickup then the motor will splutter if no surge tank is fitted. As the low pressure pump has virtually no resistance against it (no pressure) it can be a small pump, as long as it can move the volume needed to keep the surge tank full. Most external high pressure and volume pumps are noisey. Overall the VL turbo pump isnt that bad.

ok, i'm finally gettting around to doing this. got the fuel cell, the vl pump, the surge tank, and the lifter pump
the only thing i'm worried about is the lifter pump, its specs are 4-7psi and 132 litres per minute. sound about right for a lifter pump to feed a surge tank?
i'm also wondering how to run all the lines, this is what i've come up with, will it work? what should i change?

run the return fromthe engine back to the tank as well, other wise it will heat the fuel up in the surge tank too much
you just have to make sure the lift pump supplies more than the VL pump other wise it will empty the surge tank, under no load the pump should flow more than 132l min, but test it to make sure
i've read about the return to the surge tank heatin the fuel. problem is, the cell only has three holes, two in the sump, and one at the top. will it cause drama's if i run the surge return to the hole alongside the outlet in the sump? and then have the engine return come back into the top of the cell???
My mate with the sr20 zook has a fuel cell. His came with a swinging fuel pick up, so its always in the fuel, and a foam type stuff that fits in tank to stop fuel slopping around. He has since taken the foam out with out any issues yet. He found he still needed a surge tank, though many get away with fitting the hi pressure pump below the tank, to keep it fuelled...
I have no personal experience or knowledge of it all

Fit a 'Y' piece ( think 'T' piece, but in the shape of the letter 'Y') in the overflow from the surge tank, and run the engine return into that. This way you will have both the surge tank overflow, and the engine return flowing back to the fuel cell, via the top.
Feeding the engine return back in next to the pickup will do 2 things.
1. return warm fuel to the tank where the pickup is, sending warm fuel back out straight away,
2. it may airate the fuel near the pickup. Air in fuel pumps is no good.
