So I think I have a fuel pump failure again. The third time in six years! I’ve had two AirTec and now one AC fail in that time. The car has been flat bedded three times in the 25 years I’ve owned it and all due to the pumps failing.
Got to get her back on the road and open for suggestions of what brand you’ve had luck with. 327/300 engine.

Is your tank original ?

2nd time

When you remove the pump, is the spring and arm still intact and hard to push? Can you blow thru the pump at the outlet and get air out of the inlet?
Trying to diagnosis the failure of the pump with these simple tests.

I hate that sort of thing, kind of ruins the day. Hope you can find a fuel pump to fix the issue once and for all time.

Yes. Clean and shiny inside.

Fuel pump both times?

I don’t have the pump off yet. It broke down last evening in the middle of a busy three lane intersection and I was in no mood to check much when I got it home. Three strangers eventually pushed me into a parking lot. Blessings to them!
I did disconnect the fuel line, crank and had some gas come out but not much. I’ll check the tank sock and rubber hoses before I start on the pump but with my history with pumps and the fact the fuel hose at the inlet is only two years old, I’m betting on the pump.
The first AirTec had the arm pin move out that messed up the spring and arm. The second, which was a warranty replacement btw, went out because the inside valves weren’t staked and one fell out! I have a warranty replacement sitting in my basement that I didn’t use from that incident. I changed brands to AC and now this.

I went through 3 pumps in 6 months last one I got 12 miles out of it. I gave in and went to electric 2 years ago so far no problem

No, in my case mine was an inop fuelie that I converted to electronic (electric fuel pump). The computer I used was a reman. In a case like mine this reman core had an intermittent problem where it would die after a long time running (getting warm I assume) which probably wasn't long enough to not pass the test and inspection. After getting a flat bed ride home twice I got suspicious and started carrying a spare computer. Next time it died I just plugged in the spare to drive home which confirmed the problem.

This is also why I posted in another thread (....your ride along tool kit) my main tool is a cell phone with the business card of the local towing service.

Mine too. I sat in the middle of three lanes dialing up my saved AAA number. Gave them the information of where I was and I needed a flatbed. Three guys had parked in a nearby Red Lobster parking lot and worked their way through the traffic to get to me. They then pushed me into the lot to wait and stayed awhile.
Every time I’ve broken down there has been help from strangers to get the car to a safer area. I have done the same. I’ve even loaned my tools and help to a vintage Mustang owner to get it going again! 😂
This old car stuff is a brotherhood of sorts for sure.

This is not the answer for the poor quality of pumps and many replacement parts we get today, but I remember back in the early 70's, I had a fuel pump failure in my 1st 62 and installed one of those pulse electric fuel pumps and bypassed the mechanical pump completely. At that time I didn't want to open Pandora's box by swapping out the mechanical pump and possibly running into other problems, as it was my daily driver and I didn't have the money to pay a shop to do it.

Thinking about it, would an electric fuel pump solve some of the issues with the high evaporation rate of fuel in our carburetors today? I can remember hitting the key and hearing the pump run rapidly for a second or two and then stop once fuel was in the carburetor. Seems that would help for evaporation too. I was reminded of our "today" fuel issue just this week, as I started the 62 after 3-4 months and it took (five) 2-3 second cranks of the starter before the engine came to life.

I went with a Holley high performance mechanical pump after a couple pumps failed when the lever arm pivot rod failed by wearing thru the pump body. The Holley pump has benn in there about 10 years now with zero problems.

Just an update on my problem break down. It was another fuel pump failure. I took it off and then apart and found the whole bottom of the pump under the diaphragm filled with gas. I don’t know how the pump actually works mechanically but I’m guessing the diaphragm had no way to function if it was trapped between two layers of gas. I didn’t find any tear or hole in it.
Anyway, I’m back on the road again. Hoping for the best….

Try and find a good original AC pump to rebuild correctly. Check the fuel pump rod that goes to the cam as well.
