I had to have mine done. I suspected the use of cooking oil but the numbers who have had this particular peice of keyhole surgery without using cooking oil make me believe that the original seals have a lifetime of 15 years or thereabouts.

Tend to agree. I had a leak and lived with it for about 3yrs. During that time I used 20% veg oil a decent part of the time and never noticed much difference one way or t'other. 50% veg oil and higher, as some have done, might be a different kettle of fish mind you :roll:

Hey i know this thread is now a few weeks old but i have just noticed that i have a leak coming from my fuel pump looks to be coming from the side plate and domed cover. I have a look on the fact sheets and it seams easy enought to do. So what my question is.... is there any issuses after you folks have replaced the seals... i.e timing issues or fueling problems its just i know diesel fuel pumps to be a bit of a specialist area and can be expansive when broken! :?

Thanks

No, just keep everything clean and if anything falls out, make sure it goes back in the right place. :D

Tried the brake fluid trick and it's worked a treat for a couple of weeks now but got some new seals which I'll put in as soon as I get chance.

Just a thought re the brake fluid trick...

Wouldn't it be more effective and safer to put some in via the fuel filter rather than the tank?

Then it is where it is needed and also doesn't leave niggling doubts about whether it has mixed or settled in the tank.

This is the method I intend to try. Any see any reason why I can't use a high concentration if it it going to be forced through the pump and out of the exhaust uncombusted? Assuming a good battery to do a fair bit of cranking.

Why not crank until you have neat fluid in the pump then leave it there for a few hours to leach into the seals?
Let us know how you get on Frank. :wink:

New Bosch seals are a different "rubber" compound than the old ones (also coloured green, suit you Mel :wink: ) they're supposed to cope with biodiesel better than the originals. They also have a ridge around the sealing face................oh, er missus
