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

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.

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

Barry,
Would you share some details on the mfg. etc. of the clear in-line plastic f
uel filters you installed for each tank? I think I would like to do the same
on my 6A. Don't know that I need the filtering but like the idea of being a
ble to see the flow. Check my gascolator each year and never find anything i
n there.

Dale:
The fuel filters are from an automotive store. Get the ones with a LARGE
nipple at both ends. You maybe able to do a little research and find the
GPH or GPM flow rate of the filter via part number. Or it maybe written
right on the package. The cost of the filters were under $5 each. I had
to add a small piece of rubber fuel tube (4 ea) and GOOD hose clamps
(Breeze Eastern) (8 ea).
On the RV6 the electric boost pump is located on the pilot sidewall and I
just came out of the fuel tank into the filter and then into the boost
pump. Might as well filter the fuel to the pump. CLEAN IS CLEAN.
The reason why we did this is we had some crud in the tank and no matter
how much cleaning we did there was always something. It showed up first by
preventing the boost pump from pumping... NOW! The pump still flowed
fuel, but the pumping stopped. The fuel filter shows fuel flow, shows dirt
can be back-flushed BUT is so cheap it is better to replace it.
NOTE: Read the install instruction on the filter.... It has a direction of
flow stamped on it.

I used these types of filters to flush the fuel tanks and lines on initial
build. Cycling a few tank full of fuel through these filters and temporary
poly tubing and back to the tank is a good way to get rid of the junk
(mostly proseal flakes) before first flight. They also comes in handy for
doing the fuel level probe calibration.
I would caution however against using anything in a flying plane fuel system
that involves rubber hoses, plastic filters and hose clamps.
Van's sells a very nice inline fuel filter (the Air Flow Performance unit)
that is easy to maintain, meets all engine manufacture requirements, and has
proper AN fitting. This filter is also large enough so that if you do have
some crud, you will have plenty of filter left between annual cleanings. If
you have so much crud that you even see any significant amount at annual,
the answer is to fix the fuel tanks as this is not a safe situation. It is
recommended the filter be installed between the fuel selector valve and the
electric boost pump.
