Capen" Subject: LycomingEngines-List: IO360B / O360A Fuel pump gasket 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 RV6A N822AR - reassembling after inspections brought on by the tornado induced prop strike by my hangar door. ________________________________ Message 2 _____________________________________ Time: 07:17:56 AM PST US Subject: Re: LycomingEngines-List: IO360B / O360A Fuel pump gasket From: FLYaDIVE 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 On Sun, Sep 9, 2012 at 8:38 AM, Ralph E.

Capen" Subject: RE: LycomingEngines-List: IO360B / O360A Fuel pump gasket 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.

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.

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.
