67 GTX

I’ve gone through two Edelbrock Performer Fuel Pump’s in the last month (Edelbrock part # 1723). After the car is driven for an hour, the pump cuts out. I disconnected the fuel line to the carb. and cranked the engine over; no fuel flowed. I had good flow from the tank up to the pump. When the pump cooled down, it worked for about twenty to thirty minutes, and then cut out again. Right before it would cut out, the car would begin to surge and sputter, then die. This is on my 440.

Has anyone else experienced something like this?

You'll likely get many ideas. I was having repeated fuel delivery problems with my '68 Polara 318 mine that after troubleshooting just about everything and changing some of this or that including the fuel pump twice, in my case it turned out to be a worn cam eccentric that wasn't properly operating the rocker arm on the fuel pump. Last thing I would've expected. Installation of an electric fuel pump solved it.

We ran into a problem with the Edelbrock Performer fuel pump on my 440. Two pumps failed. Whenever the car ran for a length of time, the pumps cut out. When the pumps cooled, the car ran. When they got hot, the car shut down. Edelbrock couldn’t give me an answer. They did state that the pump was made by Carter. Carter told me that a return line was needed. Carter stated that expansion would stop the check valves from seating. A return line would circulate cool gasoline, cooling the pump off. My comment to the Carter tech was that since the car never came with a return line, Carter should have stated that one was required for their pump.

Has anyone else had this kind of problem?

I find it difficult to believe this is a PUMP problem, unless the quality of the internals is no poor that the valves warp / stick/ melt under heat!!! ???!!!!!


Seems to me this is probably a vapor lock problem instead, in which case a vapor return system WILL help immensely. I'm a huge believer in these. First one I ever saw came on my '70 440sixpack RR. IT WORKED.

I just got through adding one to my 67. Brazed a tube into the front of the tank on the driver side face of the tank. I:

Used an awl to punch a hole, carefully enlarging it until a 1/4" tube was a "friction fit."

Disconnected the vent tube, and plumbed BOTH the new tube and the vent to scrap fuel hose and tubing, which lead past the rear bumper.

Plumbed the pickup tube to my MIG CO2 bottle, using a constant low pressure stream of CO2 to flush the tank.

I actually lit the vapor stream coming out the two tubes until the CO2 came out, then allowed it to flow for about another 3 minutes.

Finally, I removed the filler cap to relieve any pressure, and simply brazed the tube into place (Hi temp silver braze/ solder)

Use Wix 33040/ 33041 filters, they are 5/16--3/8" fuel fittings respectively, and have a 1/4" return orifice built in.

You can mount them vertically or horizontally, just as long as the 1/4 fitting is on the "top" side.

Well, Carter did say that the pump is designed to be used with a return line. Once the car cools down, the motor runs.
But yesterday, I sucked on the fuel line, and fuel came out. From what they've told me, this means that the check valves in the pump are not sealing.

I think I'd press "higher up" into the Carter / Edelbrock/ Chineseo network. This sounds to me like a BS answer. Maybe after Edlebrock took these over, the "China syndrome" hit them. MAYBE they have a QC issue.

Pull the fuel pump pushrod and measure, it should be 3 1/4" long. They ride on an ecentric on the cam and have been known to wear, hopefully the cam didn't go flat, that happens also.

Is your pump at the tank as it should be, electric pumps like to push fuel not pull. Also make sure grounds are secure on pump and switch.

Sorry bud just try to help, but I don't need to.

I have seen a unvented tank take out a electric fuel pump, just for kicks and giggles check out the tank vent.

I've also seen a shop rag in the fuel tank give a guy fits because only sometimes would the fuel not flow.

If that the case... Throw the POS away and install a new one... Try this one with 3/8 barbs and hose >>>>> https://www.jegs.com/i/Carter/180/P4600HP/10002/-1
Just my 2 cents

Although you can get a bad fuel pump out of the box, I highly think it is not the pump.
