Need a new fuel pump
« on: 14 September 2009, 18:42 »
Hey guys my 16v gti turbo needs a new external fuel pump. Will it be high pressure or low pressure? I have been into GSFs lincoln and the guy seemed a few sockets short of a set if you know what i mean and couldnt get alot out of him. Direct links would help!

Thanks....sam

Low pressure is in tank and usually referred to as a lift pump; high pressure is bolted to the floor pan in the fuel pump housing.

16v gti turbo?

Yes...its the standard 16v gti with a turbo kit bolted to it (bit more advanced than that, gives 240bhp at flywheel)

if its standard pump, it will be this set up as on sale at ebay:   Item number: 120465175428 or just the pump:    Item number: 320423836528. i had to replace mine so i brought a second hand set off ebay. brand new is about £150, £200. make sure its the pump with the banjo thread fitting. :grin:

Turbo technics may or will have raised the fuel pressure, so the pump might be different.

Yes, but will the pump support the extra flow needed by the turbo?

I'd investigate further to find out what pump was fitted to it, because assumptions have a nasty habit of back-firing, or running lean at high revs.

As above, I have seen one of their conversions before and it was running a different pump.

from my research the std pump can cope with up to around 280bhp, its a pretty high spec unit. though thats probably if on EFI rather than k-jet...

some figures to be found here, if you know the bosch part number:
http://www.boschfuelpumps.com/specs.html

edit:
right a bit more digging, MK2 16v pump is 0 580 254 033, specs:
Pressure：5bar
Flow：128L/Hr

in comparison the Bosch Motorsport '44 pump (0 580 254 044):
Pressure：5bar
Flow：200L/Hr
