View Full Version : Fuel pump issue?

Ever since I've owned my GTT, I've always felt the fuel pump was a little noisy. A strange whirring electrical noise from the rear that most people complained about when they cadged a lift.

Tonight on the way home I noticed that the noise was now more mechanical, and was now pulsating - a sinusoidal type pitch if you like.

This was then followed by a distinctive lack of power and cutting out - symptomatic of fuel starvation. It got progressively worse until I finally had to be towed home.

Does this sound like a faulty fuel pump?

I'm aware of other components that could possibly play a part - main pump relay, auxilary pump, aux relay, fuel pressure regulator, carb float...

The one i got from GSF doesnt seem to make any noise either.

The reserve pump makes a hell of a noise when its going for it though !!

If you need a decent upgrade use the mk1 golf gti pump from gsf ;) more than up to your needs and not noisy (h and good price ans straight swap).

How you mount the pump makes a difference, can get a fair bit of vibration if not done correct. I need to get some bushes lol

Try running a bosch 044 pump ;) then come back and moan :D:D:D:D lol

i thought they had in-tank fuel pumps.? or was there a switch over at some point?

so... in amongst all those comments I guess you guys are trying to confirm that it is indeed the fuel pump that needs replacing?

Are there any ways of confirming/testing this?

Do a bench test, take the fuel pipe of and messure the flow rate then go from there.

K jet cars have an external 5bar pump.
