Fuel pump parts

Gaz · 14-09-19, 03:05 PM

The CQ has been out of commission for a little bit and just went to start her up and the fuel pump is leaking fuel.

I THINK it's right on the banjo from the pump. Or maybe the rubber pipe.

Either way the banjo is pretty rusted .

Anybody know where I can get a new banjo and bolt and fuel line the correct size?

Also knowing the relevant sizes for those parts world be great for future reference?

Cheers.

It's amost certainly the rubber pipe that has split through old age. I got new components to re-make all the flexible fuel lines via eBay from a company in West Midlands called Engineers' Mate and another outfit called The Green Spark Plug Company who both supply small bore hydraulic fittings to the retail trade as the manufacturer in Essex has a minimum order value of £150.

From memory, the metal pipe is 8mm OD.

If the fuel systems similar to my B3 then they are a big standard banjo fitting andcreadily available from eBay and elsewhere.

Cheers guys! Will first try replacing the rubber pipe then and report back.

Also.. is it possible to get a replacement bracket/metal mounting plate for the fuel pump? It seems to be very rusty. Does anybody make a new one?

I have even wondered about maybe mounting the pump and filter in the boot instead, to stop it rusting again.

You'll find the rubber pipe is attached to the steel pipe with "one-time use" crimped fittings and it isn't satisfactory to just use a jubilee clip to attach a new piece of rubber pipe - OK perhaps for a get you home fix but not a permanent job.
I had to sit down and think about it over a cuppa or three armed with the catalogues and came up with a compression olive fixing to the straight steel pipe using the bent bit to fit into the support rubber and then use proper end fittings with serrated connection for the rubber pipe. Parts cost me about £30 all told and it's a proper job. My banjo was OK and it had the serrated fixings already so re-used it with new copper washers.
The original was a single part from the fuel pump right to the front of the car, not designed for interference.

As to the bracket, try taking it off and giving it a good clean with the wire brush; it's fairly substantial and you may be fortunate. Use a spray vinyl chassis paint to protect it and new rubber cotton reels to put it back. If it's too badly corroded to use, it shouldn't be too difficult to fabricate a new one if no-one on here has a second-hand one.
