Make: Chevrolet
Year: 1964
Model: Impala SS
Engine: 327
Tran: 350 Auto

Background: The car has been sitting for about 1 years without starting
the engine.

Problem: After replacing all the wiring harnesses, and other non-engine
tasks, the engine started with no problem, except a minor gas
leak on the Holley Carburetor.

Questions: Can anyone help identify the Holley carb (see attahced pic)?
Can I locate a model number somewhere on the carb?
Attached pic dsc03108 points a red arrow to where the leak is
located, the leak is actually on the bottom side of the arrow.
There is what appears to be a "brass" bold leading into the
leak area, can this bolt be tightened? I'm not sure how many
miles the carb has on it, but I have the car about 5 years.

If I need to replace the carb, what is recommended, assuming I stay
with Holley, budget is covservative.

Thanks in advance.....

That is called a banjo fitting, there are two flat gaskets on it, one on each side, it might be possible to tighen it slightly, just don't over do it.
It appears you have a 600 holley, the list number should be on the front of the choke tower.(1850-2) is a possibility.
Of course I could be wrong, I was once many years ago,LOL.

Follow-up to dgcantrellsr

dgcantrellsr, It appears the carb is a List 1850-3, I took another pic (see attached). Does this still make it a 600 Holley? Thanks....

Flat Gaskets

Can I order the replacement flat gaskets for the Banjo fittings individually, or do I need to purchase a kit? Where can I locate the parts? Thanks again!

I would try local speed shops.

My experience has been that if you run a Holley you better get used to black stains on your intake.

Best thing to do is get the complete kit....that carb has been siting around and every gasket, o -ring and seal in it is dried out. You fix one leak today you could have two more tommorrow. If you do not know how to put a kit in it then have a pro re-build it for you that would be the best anyway because it is going to need a good cleaning and with the price of carb cleaner like it is today you could probably pay to get it re-built cheaper than you could get a 4 gallon pail of carb cleaner.

Even after getting mine rebuilt it leaked. I would fix one leak and in a few days it would leak at another spot. I gave up and purchased an edelbrock, they dont have any gaskets below the fuel level.

Good luck I hope it works out for you.

Accelerator pump, You will need to remove the carb turn it upside down and drain the gas and probably re-place the pump, You can try to snug the screws up but probably won't fix the problem. You really more then likely will have to do a re-build on the carb once the pump starts leaking JMO, probably time to re-build. But get another pump and try to re-place it first if you want might just fix it. JMO And welcome to the site :welcome: This thread is like 4 yrs old.

No problem, Just remove the cab and do as i stated, and to be honest tighten the screws don't usually work maybe for alittle bit but will start leaking again. From personal experience.

Be sure to get the diaphragm for the standard 30cc pump- not the 50cc diaphragm.

That's crazy AZ wants $17 for a 30cc pump! Summit gets like $3 for the Holley™ version- of course the S&H kills that, but still...
