Fuel pump change

[joebee]

Hi all
seems my fuel pump has given up the ghost. Can someone tell me if replacing this is straightforward?
Also the outlet pipe has a screw hose clip but the inlet pipe has a crimped clip, how do you remove this?
Have looked on the Brickwerks website and a mounting kit is listed separately from the pump, do I need this?
Thanks in advance

yes quite straightforward I would check the length of the pump pushrod (haynes) in case it's worn down too much.
cut the existing clips off.

Thanks for that Kev. Can't find any info as to how long the pushrod should be. GSF list one at 100mm, is that the length I should be measuring end to end?
As the engine has done 100k is good practice just to replace it anyway?
Anyone fitted a GSF fuel pump? Are they ok?
Had another look at Brickwerks fitting kit didn't notice it's for injection models.

Do you mean your's is a fuel injection ?

If for a Pierburg carb then this is the pump .. http://www.brickwerks.co.uk/shop?page=s ... ory_id=114 and like he say's the pipes point in the right direction unlike many where they don't and you have a sharp bend in the petrol pipe.

Hi,

If you buy either the Brickwerks one or the GSF one all you need will be in the box, except any fuel line clips. I got one that was fine from GSF, but understand that sometimes they come with the pipes in the wrong place. Take your old one with you and check at the counter before you leave!

Pushrod should indeed be 100mm long.

Easiest way to fit is to leave the fuel lines attached, undo the two 13mm nuts, lift off pump (and gaskets) and fish out the push rod. Measure, and if its good stick it back in (the right way up!)

Bolt new fuel pump on with new gaskets in place. Then swap the fuel pipes over one at a time, making sure they go on the right inlet / outlet bits of the pump. Work quickly, and fuel loss will be minimal, but do have a rag handy to mop up any that comes out.

As you will be cutting off the clips, don't forget to buy new fuel line clips. Get proper ones, DON'T use jubille clips, they will potentially allow leaks. Worth checking the conditon of all the lines while you're at it, and replacing any that look even slightly dodgy!

Cheers,

Alex

Thanks guys
have ordered a new unit from Brickwerks. Is it usual for the fuel pump to fail completely, without warning?

Hi,

Mine did (in Corley Services on the M6!) It worked on the way in, but gave up on the way out!

They have a rubber diaphragm that can just split, or the pin that the pump arm pivots on can fail.

Quick test if you want to check its the pump thats knackered is take off the outlet hose, pop it in a jam jar and get someone to crank the engine. A good quantity of fuel should come out.

Cheers,

Alex

Thanks Alex
already carried out the quick test. Even with engine running on lpg nothing comes out. Replaced filter and checked fuel line which seems to be in order.
Hope the new pump doesn't take too long to arrive as lpg availability is very poor.

as you are taking the fuel lines off the pump id opt for replacing them, that way you know ther are sound, the danger is that if you streach a cheap fuel line it will often ooze fuel, as has been mentioned dont forget to replace the clips
