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) |

My fuel pump is in the front, and I did have a recirculation line with restrictor, which I since abandoned. All seems to run cool under the hood, fuel pump, lights etc. I would address the air flow issue, make sure you are exiting 2x as much air out than is entering, this will help create a "low pressure" area and keep the air moving while driving. When in traffic make sure you have plenty of fans.
The only other issue which may cause a component to run hot is low voltage, as the voltage drops, the amps / watts goes up more heat is generated in the windings of the motor. Make sure the voltage is 14Vdc - 16vdc. Hope this helps here is a pict of my set up. Also make sure the pump is mounted properly, my Carter is oil filled and needs to be motor end down. I think Holley is motor end up. |
