Carburetor Recommendation 1965 Satellite 426 street wedge

[trguy]

Carburetor Recommendation 1965 Satellite 426 street wedge. I think it’s time for a new carb. I have a magneti marelli of all things four barrel on this car. Just bought it. Runs fine when used regularly. If it sits a week it acts like no fuel and will crank and crank and not getting any gas squirting. Will disconnect inlet fuel line and check pump. What is a great new aftermarket carb to put on this big block?
Thanks,
Jim

It's the gas not the carburetor. The fuel is evaporating while sitting. This is a problem we have all had for cars that sit. I keep a old plastic coke bottle with gas in it to put a little gas in the carburetor before starting.

I only have the one street car, so i have not tried this, but ive heard many times that the sane solution is an in-line electric fuel pump in addition to the factory mechanical one. Anyone gone this route??

Yes. I've had to do this since the late 70s when our "new and improved" gas in California was forced on us. And that was before this modern "improved gas" included corn syrup ethanol nation wide.

I would suggest Edelbrock 750 cfm. 1407. This is what I run on my 440's with good result, on an Edelbrock aluminum intake manifold. The factory installed a woefully small 625 cfm. Carter AFB on the 426. This was, in fact, the same carb used in the 383. If you are using the stock 1965 intake, the secondary bores may be too small for the bigger carb. This can be remedied by using the improved 1967-1970 440 intake.

An elec fuel pump, Carter #4594, will fix your problem. You have an excellent well made carb & it is NOT the problem.

That seems to what is happening as I have 3/4 tank of gas. It happened at auction after I bought the car. The mechanic had a gas squirt bottle and filled up the bowls through the vents on each side. It started up and no problem since. It’s only been a week and my 67 mustang with mechanical fuel pump doesn’t have this issue. It takes more cranking to start as the fuel pump gets gas back in. Seems like the fuel pump on the 426 might not be pumping to refill the bowls when cranking. Just a theory.

I don’t know about the others but we need to see some pictures of the car. The 64 Sport Fury and 65 Satellite are my favorite B-bodies, especially with the 426.

Try a half inch wood or phenolic spacer under the carb and see if that helps. On hot days pop the hood once you stop to let some heat escape.All old tricks to combat fuel boiling/vapor lock.

I would suggest

Good advice..... however, if he has an all original street wedge, id work to keep it visually all original if it were mine. Just a personal opinion.

Thanks for all the comments. Here are a couple of pics. It’s a rare Satellite with only 21 or so ordered in a convertible with automatic. I’m really enjoying this ride when it doesn’t dry out of gas. Still puzzled the mechanical fuel pump isn’t pumping the bowls back up with fuel while cranking. Glad to know this magneti marelli carb is a good one. Quick ai search and it said they bought out the Carter carb tooling in the 80s. I have the stock intake and it’s all stock except the vintage air and heat system installed which works great.

Wow, that’s nice!

Even the non ethanol dries up pretty quick.

If you have a slight air leak on the inlet side of the mechanical pump it can do what your car is doing.
The pump has two valves in it that may be leaking also causing it to lose it's prime.
You can test the pump. It should suck a vacuum on the inlet side and have pressure on the outlet side.
It won't hold a vacuum but you should see the gauge keep bumping up as a mechanical pump should be able to suck the fuel to itself.
If the car runs and starts once it gets fuel I agree with the others saying the carb is not the problem.
