Stalling problem solved !
I've posted a few messages over the past month regarding the problem I was having with the engine stalling whenever it was hot. At first I thought the problem was the distributor so I had that rebuilt. It didn't fix the problem. Then I thought it was vapor lok. That wasn't the problem either. Finally, I bought a new fuel pump and took it to my mechanic to have it installed. He put the new pump in but what he found was a fuel line which was soft and mushy :eek: He said that the heat from the engine was enough to soften it more which caused it to collapse, shutting of fuel to the carb. New fuel pump & fuel line = :D
On a side note, my mechanic said that was the most difficult fuel pump he ever installed :eek: It took him 3 hours with the help from another mechanic :eek: And this guy works on vettes all the time...

Re: Stalling problem solved ! (apple76)
Glad to hear that's all it was and interesting about the hose.
I was under the back of my 73 last weekend and checked the hose that goes from the gas tank to the metal fuel line and when squeezed it didn't have that firmness that it did when it was new. (But then this happens to the best of us as we age :lol: )
I double checked to make sure it was "fuel" line and then just figured that was just the way it was supposed to be.
I think when I get back from Carlisle I'm gonna get the best hose I can, maybe braided racing fuel line, and replace both it (the hose at the gas tank) and the hose at the fuel pump before they go totally limp. :yesnod:
Does anybody know if they make Viagra for fuel lines? :lol:
And thanks for posting your problem and solution... :cheers:

Re: Stalling problem solved ! (Brettmc)
If I ever have to replace or remove it for any reason, that is what I am doing. With the engine out it is no problem and as long as you are carefull intalling the engine, it is no that bad to have it on when doing it.

Re: Stalling problem solved ! (zwede)
From what my mechanic tells me, the average fuel line should last about 12 years. Replacing the mechanical pump with an electrical pump was something he briefly mentioned. Maybe next time... :yesnod:

Thanks for the info, that's what this is all about...Solutions to the problems.
I have a hesitation at traffic lites after it gets hot. I thought it was so the other guy got his proper staggered start time :jester . I got to go check those lines. :yesnod: :yesnod:

Re: Stalling problem solved ! (72GACRZR)
the key to an easy fuel pump change is:
Undo the two motor mount bolts (VERY easy)
Remove distributor cap
Jack the engine up with a small jack under the oil pan with a piece of wood between the jack and oil pan
The engine will easily tilt up about a good 6 inches where the fuel pump is

Re: Stalling problem solved ! (MELVIN)
Jacking the engine up does sound easy! I wonder if there would be problems with
the fan and other items such as the A/C if you tried to move the engine up :rolleyes:

BTW, I have headers. Don't know if that makes it easier than with the stock ramshorns.

Re: Stalling problem solved ! (glen242)
As far as the problem with installing the fuel pump, my mechanic didn't go into detail. All I know is that this guy has been in business for 20 years
and comes highly recommended. He builds many of the street engines for
the local rodders and really knows his stuff. I'm just happy he got the white princess back on the road... :yesnod:
