Yes, we would have to assume that the mechanical pump was the issue. I truly think that the pump was getting way too hot being only a 16th" from the radiator hose. I do have an aftermarket radiator that may have place the lower radiator hose slightly closer to pump?? I never changed any fuel...

ANOTHER UPDATE!!! Replaced mechanical fuel pump with Holley Electric (red) Fuel tank is newer, Holley and others suggested pre filter which I reinstalled. Ran car for about 25 miles straight with 0 issues. Brought it back to the garage and let it cool, ran it again for another 5 miles with 0...

JUST WANTED TO UPDATE ALL I removed the fuel filter I had installed at the tank. Problem still exists. I install a sperate tank vent. Problem still exists. I drove without the fuel cap. Problem still exists. I confirmed none of my fuel line is against anything hot. Problem still exists. I...

Yes it is

I am going to order the check valve and utilize the vent on top of the tank. My gas cap is non-vented so I am thinking that maybe this may correct things. I will report back in a few days to update. Of course its calling for 5 days of rain so it may be a minute...haha thanks for all of the...

The fuel lines are not against anything hot, however, I really think the lower radiator hose is too close to the fuel pump (3/16") but that's factory. I am just running standard high test pump gas.

Unfortunately, I didnt finish it until hot weather for the test drives. I can tell you that while breaking in/tuning while in my shop, it did it then. My shop is conditioned, so it was probably 74 to 75 in here.

I do not know of an actual tank vent that I installed during build. Could you elaborate on where this went should be installed? *I just looked at pickup installed in/on tank. There is a small nipple that has a rubber cap over it. Is this for a return or is this a place to vent? This is high on...

yes, and it did not make a difference. I have an OEM cap and no vent system that I can remember during the restoration.

You may have a point here. The rear filter is sized to capture larger particles while the one at carb is for finer. Its just odd that it takes 12 miles of drive time for the problem to occur.

the bowl empties while the car is operating, not when sitting. So, while the engine is running, it eventually loses fuel pressure, bowl empties, engine shuts off. Must reprime the carb (or crank the motor for awhile) then the engine runs normal until the problem repeats itself, after about 12...

Hello All, I have put about 150 miles on my new build, 1972 Dart Demon. During this time, I have changed the mechanical fuel pump three times due to fuel bowl becoming empty. Yesterday, I drove about 12 miles to a car show and while parking, again had 0 fuel pressure and no fuel in the fuel...

thank you for your response!! I used a tester and went through the pin and manually figured each one out. If anyone needs this info please let me know. thanks all!!

Hello, Does anyone have a diagram or chart showing what each color wire of the 10 pin connector represents? thank you!!!
