the fuel distributor 9the thing that bolts to the metering head) should be a sealed unit.. the only thing that touches the metering head is a push rod thingie, so no fuel should leak out fo the fuel distributor.

i think new/reconed fuel distributors are about 300ish quid (theyre NOT serviceable) speak to your nearest bosch dealer

there is a seal mate, and they often go. Stu has got some, but he's away at the moment - but think kenny is there so give MD a call. While u have it off, make sure the plunger is going in and out nice and smooth and not gunked up.

RS Bowk

there is a lot of mess round it i will check that should the plunger just push by hand?

and is this a common prob with an rst?

Jim Galbally

rick, but there should be no fuel leaking from the distributor!

there's nothing's mysterious about the fuel distributor if you open it. A couple of o-rings and a main gasket that can be changed.

RS Bowk

where can i get these O rings and gaskets from as it didnt show up on the screen at ford 2day?

Jim Galbally

jesseT i know a few people who've tried...

they all failed to get it to seal properly upon refitting

JesseT

From Bosch.

RS Bowk

ahh right cheers mate do u know if any O rings fit (providing there the right size of course) as my time is runnin out as got trax on the weekend.

im presuming uve done this urself 2 yeh and had success?

my mate messed around with the fuel metering unit on a s2. proper messed it up as didnt have a clue what he was doing. ended up paying 100's getting it re-calibrated! id tread carefully!

do a search on google for kjetronic metering head and youll find a webpage someone put up describing in intricate detail how to rebuild the fuel dizzy...

please note that the last section states "after i did all this i put i abck together and it leaked and it was fucked so i threw it in the bin and bought a new one"

i shit you not... theyre not a user serviceable item..

RS Bowk

yeh but its not the not the top unit thats leakin its the alu part that joins the rest of the metering unit ( that joint there) and there is def supposed 2 b an O ring there and there isnt it was jus silicond up hence my leak i think!

Rick

Bowk - call motorsport developments - i know for a fact they have these seals.

JesseT

Yes, there is supposed to be an o-ring in between of the distributor and the main body, but it's not for keeping the petrol in. It's just for keeping the dirt out. If you're getting petrol as far as the o'ring, then something else is fooked in the distributor itself.
