[MODERATOR NOTE - Sarcasm alert! - please don't take these suggestions seriously - humor intended!] Walter, My guess would be that the radiator cooling pipes that run along side of the gas tank are the major contributor to the heating of the fuel in the tank. You are right about the other sources of heat gain. If the pump is extremely noisy, check and make sure that the fuel inlet screen is not clogged or that the hose has not been pinched or collapsed. Coming back from the Cleveland show, my pump sounded like a garbage disposal. I ended up stopping every hour or so to fill the tank up with cool fuel. It turns out that I had bought a load of extremely dirty gas in Cleveland. The noise was the pump cavitating because of a clogged suction. Warm/Hot fuel will cause the pump to cavitate and is aggravated by a lower fuel level in the tank. A deflector for the air coming off of the radiator may give some relief, route the air from the fans to the wheel wells. We might have to install cross drilled brake rotors to compensate for the extra heat from the radiator to the brakes. We could route the cooling lines thru the passenger compartment and bonnet to the radiator. I know, put a AC loop inside the gas tank, we could refrigerate the fuel. How about mounting the fuel tank inside the passenger compartment on the rear package shelf. This would increase the trunk capacity. We could mount the radiator horizontally on the rear louver or even put in one of those VW air-cooled engines. The possibilities are endless. Maybe the best thing to do would be to turn up the stereo when you get tired of the hum of the fuel pump. ;-) Scott Mueller DOA/DMCNEWS 002981 Original Message ----- From: Walter <Whalt@xxxx> To: <dmcnews@xxxxxxxxxxxxxxx> Sent: Tuesday, February 27, 2001 5:08 PM Subject: [DML] Noisy fuel pump > Rob Grady was right.... > Replacing my old noisy
