Christian, if it was rebuilt by me, I'll be more than happy to check it out, even if I didn't do it, I'll still be happy to check it, but I don't think your problem is with the pump. If it were, the problem would be there all the time, hot or cold. Fuel percolation maybe?

Thank you
That's a 14 page thread.
Can you tell me what page the "fix" is on?
The first few pages are, I think, background for why I went with the "fuel-pump with no toggles switches" route. Can't narrow in on one paragraph on that thread.

Actually.. yes, that would be fantastic!

yeah...I have a full time job that is quite demanding, forgive me asking the thread author to quickly direct me to the page where he found the fix. I don't have the time while at work to read through all the filler. MY BAD

And please advise what IDFBI means, guess my forum whoring isn't up to snuff on the lingo.

Started it this morning after letting it sit over night. Still VERY hard to start and needed starter fluid again.
Thinking I might have to go the in-line electric fuel pump route. Hate to add something the care didn't come with from the factory.

Anyone know if a low pressure pump such as this one from Amazon will do the trick?

Any electric pump with 4-7PSi will work. Just remember that you get what you pay for. A cheapie pump may not last very long, but it will work in a pinch.

As a newbie on here firstly i have a 65 4 door
the issue i have is what seems to be lack of fuel at the carb so previous owner added a primer pump...
This i think helps and saves on cranking but on acceleration it feels like i have fuel starvation and the engine dies then picks up then dies etc until it catches up as ive backed off.
As for fuel draining back i don’t think that the issue but an explanation on the fuel content makes sense as i have an old vaxhaul that wont start unless i give it a cap of new fuel.
Im debating whether to rebuild the original pump if poss or run electric as main pump with regulator etc..
suggestions welcome..
cheers

It does sound like the pump isn't keeping up with it's half of the work-load. Very possible that one of the valves is having a hard time sealing and the electric pump is just pushing it's way thru.

Damn, I've been selling cores for only $125 when it's $100 to rebuild.

I've been giving them away.

John's pumps aren't cores, they are complete ready to go ones. But I understand what you're saying.

If he's selling them for $325, plus shipping, he's making around $70 more than I do.
No biggie. I'm not willing to make the investment in the rebuild beyond myself.

Vern, my '62 was converted to electric by a previous owner, the mechanical was completely disabled, and I had similar symptoms: it started right up but would hesitate and die after running for a while, and would struggle on the highway. I was uncomfortable driving it because it always seemed like it wanted to die on throttle after a stop.

I recently had Mike rebuild the original carter and converted back to 100% mechanical. As part of this restoration, I found that the push rod was extremely worn and replaced it as well. I suspect this push rod was what lead the PO to convert to electric. With no electric it is hard to start, 15 seconds of cranking or so to prime the lines, but it runs like a dream.

I would restore the mechanical, replace the push rod, and only then add an electric if starting is a major issue even after a tune up.
