Fuel pump got even with me for non use.

The Holley mechanical pump I bought broke after a couple of thousand miles. They have a bad reputation. Avoid these at all costs.

I replaced it with a stock pump and it has done fine for many thousands of miles. I went to Checker and asked for a pump for a Mustang with a 351C. As you might guess, mentioning a Pantera will get you nowhere. No mods necessary.

Something to check before you dive into the pump. Pull the banjo fitting at the top of the tank where the feed line attaches. Check to see that there is no junk blocking the small orifices. Perhaps blow some air back down the line. Some cars pickup from a tube in the sender plate, so you might not have the banjo fitting.

Yeah i was reading about just getting a stock pump. Sounds like the best idea. I know that damn pump is only about a year old but wasnt used much. Yeah I know the inside rubber can go bad from being dry. I will replace all fuel lines again. I dont have a banjo fitting on top so thats out. I thought about that too, something might be blocking the line. Doesnt look like thats it, even though there is 0 gas being pumped through the fuel line. I think my distributor is stuck in place too. I sure dont want to break the shaft. Was thinking of spraying it with some WD40 let it sit, and then try a large wrench and ease it a bit. Thats secondary to the pump. Kinda sucks when a inexpensive part holds up all your fun.

I just run an Autozone stock style pump and it's been fine for 4 years now. My carb is a 600 Carter Afb same as Edlebrock. If you don't need an electric one then this should do. I always tell the guy at the parts counter that I have a 72 Ranchero with 351C. You might want to put new fuel line while you are at it and new filter in line. I live in Whitter, Ca.

Who says it has to be inexpensive?

There's the RobbMc pump that costs $175 (and for an extra $100 they can upgrade it to handle 1100HP), so it can make you feel better about the price of the part that's holding up the fun ...

Here's the thread where it's discussed ...

*** NOTE: if you decide to go for the RobbMc pump, be sure to read the entire thread, it looks like some folks had trouble installing the pump with the engine in the car and with the fittings (or lack) that came with the pump.

Good luck with the repair!

Yeah it would be worth it if I had 1100HP but I dont. Haha if I did I would be out right now getting a ticket. I will try another stock one from autozone. Will replace all lines and the fuel filter.

OK I see it at the top of the tank. I did remove the old stock furl line. Wow was that old. Braided line must have been pretty good back then. I hooked up a new line and blew into it to see if that does anything. Kinda have to blow really hard, unless Im just old, is that normal?
I see how the banjo is screwed in looks like it would be kinda hard but I could take it apart if I had too. Rather not since theres no easy way to get to it. Should I use a compressor or will that just trash it.

It shouldn't be that tough to take the banjo fitting out and inspect it for blockage. It is just one bolt. Don't confuse it with the vent. Maybe take the side cover off.

Blowing into it would be tough if you had a full or partial tank. A compressor set to a FEW PSI and the fill cap off would work.

The reason I focus on this item, is this is the first reason I had to have my car towed home. The banjo was clogged with goobers. A new fuel pump did not solve the issue.

OK thanks. Its just that the fuel pump thats in it is not that old. But it did sit for a long time. I tried cranking it with the line in a bucket and nothing. I even checked for pressure with my thumb on the end while it was cranking, nothing. I can suck on the hose but theres a lot of resistance. I will try some compressed air. I dont have the banjo, I looked it up. I have the tube coming out. I will try aome air blown into it today. See if that does anything. I will change the pump out anyway just to have a new one in there with new fuel lines. Just worried about the eccentric. That would totally suck. I will know soon as I install the new pump and do the bucket test again. If it was just the pump I might have a chance of it running better too. Might be better off thinking positive!!! When its easy to start and it runs good I love it. But when I dont use it and it just sits there I think about selling it. I much rahter drive it every weekend.

Then you need to start driving it EVERY weekend, and maybe even during the week! That's what I intend to do as soon as mine is back on the road!

So I replaced the pump. Old one hard to tell whats up with it once I got it out. Replaced the lines. I put a plastic fuel filter in line to do its job plus so I could see if there was fuel in the line. Once I had everything replaced and hooked up, cranked it over and saw fuel pumping into the filter. Great sign!! Shut it off and checked for leaks. Turned it over 2 or 3 times and it started right up. The filter only fills 2/3 full, is that normal? I would think it would be full, but you can easy see its only 2/3 full. I included a few pics. One is from the inside of the car so you can see that one bolt is accessible. The bottom one i could get to from under the car without jacking it up. When I put the pump in I had the bolts about 80 tight and cranked the engine, I saw it wiggle a bit and figured it might be in place correctly. Tightened them up the rest of the way and was pretty happy it started. So now my Edelbrock 4506 needs adjusting again. Step on the pedal too fast and it wants to die. Think its a fuel pressure problem or carb? I have had this problem before. BUt least it starts and can run some checks to see whats up with the bogging. Thanks for the help as always. Sucks talking to the wife and shes really no help except for the (get it done) comments.

Working on the car today to try and troubleshoot whats going on with the bogging. Well, I checked everything. Out of curiosity I looked down the carb. Went to move the secondaries with my finger. Took a screwdriver since my finger wouldnt get to it. Low and behold, the weighted flap was stuck closed. Got it to unstick by gently forcing it open. Ok now it moves, started the car and much much better. Go figure, but still need to adjust it again from messing with it so much the night before. Phew!!
