1150GSA Fuel Pump swap

[Outbacksidecar]

My 1150GSA wouldnt start. At first I suspected the Hall sensor - this had failed before. Checked it with a small tester I made up last time. All ok. Next I checked the injectors. They seemed to be firing, but no fuel was being sprayed. So I pulled the hoses from the fuel tank/pump. Pump made noises but there was no pressure, and I could blow air back through the delivery hose from the pump. Not good. So it was off with the tank and pull the pump out. First photo below shows what I found. The plastic spigot where the fuel hose goes on had broken off. I did notice that the pump was flopping around and the rubber at the bottom was perished.

A search of this formum suggested the 5 series BMW car pump would fit. So I got one of these. Its a little bigger than the original so some mods were needed. The series of photos below show what I did.

All good now - bike runs well so I'm happy.

well done mate but i have to ask why not replace it with a gs pump

why not replace it with a gs pump

£££££££££££££££ i would guess.
The pump may still be a BWM item,maybe from the same factory but bike bits always seem to be dearer.

Bosch 0580 314 068 pump fits fine.
Much cheaper than the original pump
Picture, black one is Bosch

bet even cheaper still if you got a replacement from GSF or Eurocar parts

this looks the sort of thing

Two reasons for non original

1: cost - didnt price a genuine, but I expect $$$$$$. The one I got was $240 oz, double this for original(?)

2: my nearest dealer is about 500 km away. I'd have to order it in and then wait on the mail. And wait and wait etc

The one I got wasnt a Bosch, just an equivalent - and I can just go down to my nearest Repco agent and buy a car one. And if this one fails then it's easy to just get another one.

Well worth knowing that other fuel pumps will fit,
