I am adding a fuel pump cooling shroud to help prevent vapor lock.
The fuel pump gasket tore around the bolt-hole as I took the pump off to add the cooling shroud.

Anyone know where to get a replacement gasket?
It looks like an old chevy fuel pump gasket – in fact the pump has AC on the top…..

Thanks in advance,
Ralph

Barry,

Great scoop…
Already have the AD – will be checking the applicability.
Not mounting under – when I loosened the bolts for the pump, it must have been on the power stroke and starting pushing the pump up and out from the bottom.

Already completed the other precautions you have suggested.

Thanks again,
Ralph

Ralph:


The gasket is available from ACS or you can go to a local automotive store. The pump is the same as used on many cars. Start with the pump Part Number and Serial Number work from there. You will be able to ID the pump and gasket.



Now, two issues:

1 - There is an AD on Lycoming Fuel Pumps. Make sure your is not affected. Check by P/N & S/N.

2 - WHY are you mounting the shroud UNDER the fuel pump? I'm not sure if that is what you are doing but, when you mention the removal of it, that is what I envision. You could mount it above the pump and use angle brackets coming off the mounting bolts. Make the angle brackets long enough so you have access to the bolts and will be able to install the safety wire.



What other precautions have you done to ward off vapor lock? Have you:

Put fire sleeve on all fuel lines?

Kept fuel lines away from the exhaust pipes and muffler?

Run fuel lines so the supply end is higher than the user end?

Used a large enough diameter fuel line so there is no restriction, no mater if the pump(s) are working or not?



A side note: On the RV6 that I fly I have added two in-line clear plastic fuel filters (one for each tank) inside the cockpit - I can look down and see a positive fuel flow. This works way better than the gascolator.
