I'm looking to replace the external fuel pump on my 1991 coupe gt but not having much luck. The part number is 867906091 which I know has a different pressure required for a 1.3 compared to the 1.0. This is running at 2.5 bars according to the Haynes manual. If anyone could please direct me to a web site or link I would appreciate it. Thanks

Any in line fuel filter will do. Mine was meant for a ford Monroe tdci and is no doubt more powerful but fits and works well.

There are many universal fuel filters on eBay etc some have the same sized inlet and outlet and will likely only need you to chop the wiring and crimp on small ring connectors.

Having looked up the differences between Bosch universal and Bosch specific fit the only difference is the connector (if it's the same output power of course) and generally the universal ones are around £100 cheaper then the OE just for a plug and play connector.

Is there a difference in the pressure rating for the pumps? Did I read somewhere that the 3f engine needed a pump with 2.5 bars pressure? Looking at some of those on eBay linked to the number 0 580 453 918 the pressure rating is only 1.1 bars. I'm confused. Says is compatible with 1.3 Kat and g40. Could you please shed some light on it. If so there are a few for around the £60 mark plus post from Germany which is really cheap compared to the £200 odd quoted elsewhere.

best of my knowledge is that its the 2.5 one you want

will ask my mate when he's online to confirm

you can use the k jet pump if youre prepared to change the plug , thats what i plan to do

Thanks. Doesn't specify that it is rated at 2.5 bars pressure? Others on the web say they are compatible but when you dig further the pressure is often just 1.1. Will look into this and a sk my usual garage to do some research too. Thanks again.

Just reading around the pump issue and looking at the wiring diagram I noticed that there is an earth connection labelled E8 on this image. Anyone know where this is located on the car as I would like to clean it up and see if it helps the running of the pump

shouldnt be too hard to see what direction the wires go and trace it

Traced the cable along the back of the car below the tail gate where it disappears into the passenger side of the back seat area?

It is also earthed with the in tank pump according to the wiring diagram. Will look under the rear seat and follow the brown cable from there. There is an earth near the passenger rear light from memory?

Well. Spent more time on the manual and came across this. Should have spent more time on this. E8 is on the left side of the luggage compartment. Got it.

So. Left side of the luggage compartment. Found the dirties connection I've ever seen. Full of wax oil and dirt. Also looking at the earth connection to the body work top left on the photograph.
