Pump ?

[lukey4x4]

Hi , can sumone tell me if i need a electric fuel pump , my engine will run with a gravity fed bottelof petrol but wont run from the main tank , trucks a 410 with the 1.6 spi engine in ,? Thanksss

Running it as injection or on carb?

If its injection will require a high pressure pump, Vitara and late samurais have them built into the tank

If your running a carb it will need a low pressure fuel pump.

Just leaving it as it is jordi injection mate , could i just buy a universal out of tank one ? Thanks

[Jordi]

I would have thought so, not sure what pressure it needs to be though. Probably get an in-line pump for about £35.

thanks was lookin at this on ebay item number 360881928243 u think that would be ok thanks

[twiss]

I think they need to be somewhere in thr region of 15psi for the spi injection...

Cheers mate think i will look for a diffrent 1 then , that one was 8.5 bar max = 120 psi maybe bit to much thanks , do u just fit these by puttin it someware inbetween ya petrol pipe nwire on up to egnition earth n egnition live or a switch ? Thanks

They recommend wiring it onto the oil pressure switch i think. So it cuts if when the engines off / stalls.

Easy enough to do, mine came with idiot proof instructions.

This is from the se416 (vitara) workshop manual. I would assume that ebay pump would be OK.
It's standard working pressure is only a little above the pressure required for the SPI.
The pressure regulator should keep it at the required PSI.

The pressure is about 38psi but it is set by the regulator not by the pump, the pump just has to be able to work against that pressure and provide enough flow. That eBay pump should be OK, its nominal working pressure is 3bar which is standard for EFI.
