I have an overheating fuel pump in the front trunk. I think it overheats because of the heat coming off the radiator and screws up the pump enough to so I loose fuel pressure down to 1psi.
The pump is a new holley red w/a holley regulator. The pump gets so hot you cannot keep you hand on it. I iced it down a bit and my pressure immediately comes back up. I considered the heat could be from the pump, but the wiper motors also get too hot to touch. So where do you mount your pump (if not in the front trunk)? Or what kind of pump do you have (if in the front trunk)? ..or maybe I have to cut more openings..? (IMG:style_emoticons/default/idea.gif) |

Here's the specs on your red holley. My holley was brand new out of the box and it got hot...I don't think it has anything to do with air flow. My guess would be now the wiring. PS If you wanted to have a return line for fuel, holley makes a nice pressure regulator with that extra port. Mount it in the engine bay and run a return line (unless you still have your stock line still there). I didn't think about meauring voltage when I had it apart. When I put on a smaller pump it ran perfectly cool...my bet is with the wiring. Need to measure amperage draw. Since it only is suppose to draw 2 amps (fused at 7), you should be able to put a meter in line like Tony said.
Tumble Polished Billet Look New Lower Housing Casting for Enhanced Fuel Flow and Quieter Operation Maximum Pressure Is 7 PSI Motor Draws 2 Amps Current 7 1/2 Amp fuse recommended Constant Fuel Flow with No Pulsation Improved design for street/strip applications Distinctive “RED” logo Flows 97 GPH (free flow) Flows 71 GPH at 4 PSI Regulator is not required Has externally accessible pressure relief valve (max 7 PSI) Rotor/Vane pump design is more tolerant of contaminated fuels Weighs only 2.88 lbs Includes mounting bracket Repair kits are readily available Can be serviced from either pump end or brush cap end NOT compatible with alcohol or methanol fuels Use of safety shut-off switch, P/N 12-810, strongly recommended Not designed or recommended for use with fuel injection systems |
