Fuel Pump Gaskets - DG

[StuM]

Hi folks,

I want to check the length of the pushrod on my fuel pump but before taking the pump off, I want to get the gaskets to replace when refitting. I understand that they have two - bakelite spacer to block and pump to bakelite spacer.. but can only find the lower gasket advertised. Is my understanding wrong?

Thanks,
Stu

You are right
I had the gaskets in a full gasket set but not seen the upper one for sale
I haven't done it but I can't see why you can't use the same gasket top and bottom?

or make one from Gasket material looks like this...

Thanks for that. I'll get some gasket material, good plan

Hi

How did that work out for you.??

I've got an oil leak from the fuel pump, and before I whip it off, I want to get all the parts but as above, I can't find the top gasket for sale anywhere. I've ordered two of the lower ones instead. Anyone fitted the lower gasket on the top?

Bought a new space and rod too, thought I may aswell do a complete job, given how little the parts cost.

Got a few oil leaks here and there, so working my way down from the top. Also it looks fairly straightforward and I'm still very much a beginner.

Anyone who owns a T25 would do well to keep some gasket paper handy. It'll get you out of all kinds of trouble. You CAN use cornflake box material if you're stuck but gasket paper is infinately better. You could also use high temperature sealant from a tube too - around a fiver though in most places.

Worth noting though - the profile of the pump is identical to a type1 beetle so if you're struggling, go muse a bug parts site.

Look down this page: http://www.ebay.co.uk/sch/i.html?_trksi ... &_from=R40" onclick="window.open(this.href);return false;

I can see one. I'd still make one though.....

Yeah I saw that it looked similar. I would have got one when I bought the rest but they were out of stock.

Think I'll get some gasket paper and make my own.

Beginner question. What type of grease do you pack the spacer with? I haven't got any grease so I'll need to get some. Aware that there are different types. Do I just need bog standard grease?

[CovKid]

Yep, straight bearing grease. Nothing fancy. When you get the gasket paper, press it hard against the pump base with your finger tips, working all around and it will leave an imprint/mark on the paper that you can use as a guide to cutting. You don't need to be too precise with it - as long as it all bolts down ok. Don't overtighten.

Thanks for advice. Spent the weekend dealing with rusty windows, so I'll be tackling this next weekend.

Hi,

I found a great tip on making your own gaskets on a random classic car website (think it was for old MGs but can't find it now).

Chop the gasket paper to roughly the right shape / size, but with a fairly generous overlap. Hold the gasket paper firmly against the thing you are trying to seal, and then tap gently round the edge with the rounded end of a hammer. The sharpish square edge cuts through the gasket paper surprisingly well.

Done a few like this now, they have the advantage that as the actual sealing face is being cut round, they don't overhang (good for inlet manifolds!). With a small hammer I found you can even cut the bolt holes out for an M8 bolt. Works better for me than drawing round or scanning the item then cutting it out with a knife.

Cheers,

Alex

Well worth pointing that tip out for those that did not know it Alex

With a small hammer I found you can even cut the bolt holes out for an M8 bolt. Works better for me than drawing round or scanning the item then cutting it out with a knife.

That is the bit that often gets me. OK for larger bolt holes, but making the holes for things like carb gaskets is always more difficult, (well for me anyhow )
