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) |

Computer4kids - My pump is similar design to your's, except a holley red.
I measured voltage at the pump is 11.4v (Is that too low?) but off the alternator and at the battery is 12.1v. I may have to wire a direct circuit + relay to power the pump. I will try a sheet metal box around the pump and insulation to protect it from the radiant heat. If it still get hot, maybe it's back to the pump? I thought about using a carter, like I have on my other car, or a mechanical pump (datkotaewing). |
