Car struggles to make fuel pressure

Mitco39

Stock wiring? wow. I ran 10Ga back to the tank yesterday and got it to the point where it gets warm to the touch but it is no longer hot. I attribute that to soldering my connections instead of using splices as I imagine the internal resistance of a buttsplice is significantly higher and thus got hot.

That said after the car warmed up the idle fuel pressure dropped again. I was doing some reading and have read that fuel pressure gauges can easily be affected by heat and that this is normal. I do know that regulator gets hot to the touch when the car is driving around.

For example the fuel pressure when cold sits 58-60PSI, hot at idle it sits around 55-57psi. I am going to do some more research when I get time this morning to see if thats normal and if it is a possibility that its the heat affecting the sensor.
