From: teamgrumman@aol.com I isolated a bad fuel pump by installing an in-line fuse in the wire to the electric fuel pump. So, in effect, I had two fuses to the fuel pump. The closest fuse will blow first. I think I used a 5 amp fuse. It turned out the pump was failing. Replacing the pump stopped the problem. -----Original Message----- From: Peter H. Wei Sent: Sun, 17 Jun 2007 8:24 am Subject: RE: TeamGrumman-List: Fuel pump blowing a fuse? I had the same problem about a month ago. I found the fuse was getting blown after the strobe lights were turn on. This only happens intermittently. I checked the wingtip strobe tubes and found the right wing tube had turned black. I replaced the tube and the fuse has not blown since. Hope this helps.

Sequence goes like this: Master on, fuel pump on, silence (except for the gyros spinning up.) Strobes, fuel pump, and starter are on the same fuse. What about a fuel pump would cause this problem? Is is a wiring issue inside the pump body, or more likely some short otherwise. Testing the circuit with the battery disconnected shows good connectivity through the fuse. No short between the power source and the fuse body. Replace fuse, master on, stobes work. Strobes off, fuel pump on, blown fuse. Anyone had this experience before? Is is just a common fuel pump failure? Thanks for the input.

As I mentioned you could have accomplished the same thing with the panel mounted fuse by cutting the wire to the pump turning on the switch and then temporarily shorting the two wires you cut together. Either way you found the problem. A good modification to the electrical system is to put the electric fuel pump on it's own circuit I think.

A picture or two would also be helpful. I've read the GG archives and seen pictures of some of the retrofit solutions, but I'd like to see what the latest factory solution was.
