Lift Pump Flange Gaskets
Lift pump flange gaskets are usually robust and do not require replacement. It is only if there is a leak in the lift pump or the pump is removed that replacement may be required.
Diesel fuel leaks, are not only expensive, but they are also dangerous and damaging to the environment with potential contamination to the engine oil. If the diaphragm perishes or tears, the diesel can leak into the sump, diluting the engine oil and can lead to a seized engine.
In the past, flange gaskets were made from CAF (compressed asbestos fibre) but all gaskets are now made from paper, and that has been the case for some time.
If your diesel engine does have a persistent fuel leak from the lift pump it is advisable to get it rectified as soon as possible. It could be a failed gasket, O-ring or rubber boot that is fitted on the diaphragm stem that could be the issue. The tell-tale sign is if you have a puddle of diesel under the engine after if has been left to idle for a period of time. If this is the case and you decide to rebuild the lift pump, we would recommend that you replace all of the gaskets and O-rings to be really sure that any possibility of reoccurrence of the leak has been removed.
Whether you want a two, three or four hole fixing seal between the engine and the lift pump, we are likely to have them in stock at Darwen Diesels.
