I have a 65 mustang with a 351 windsor under the hood, after sitting for 10 months because of a drivetrain issue that I am now finally getting fixed, I found that she is leaking heavy amounts of fuel out of the carb. Starts right up, runs alright as far as I know because as of this moment the drivetrain issue is still there. Question 1. E3TE-9510-RD, LIST 50003-1, 2984. That's the set of numbers on the carb, from what I've searched it's a Holley 4180 600 CFM, I just want to make sure that's true. Question 2. Should I get this one rebuilt for a cost of $150 or get a new one at about a cost of $350, best bang for the buck? idk, what would be the advantages of either? Thank you for your time

Hello allrightythan89,
This is a tough question to answer and I will explain
There are a bunch of thoughts that others MAY have as well.

My thinking - your carb is older and may have internal issues
For this reason - I would not pay to have it rebuilt.

I would however consider rebuilding it yourself. The rebuild kit
would cost about $40.00 - -BUT the drawback is there are a few
pieces that MAY be hard to work with during the rebuild
Here is a link
http://www.holley.com/data/Products/Technical/199R10060rev.pdf

The link tells you about replacing a few pieces that MAY be a little
tough to do if this is your first rebuild.
Trust me - normally a Holley is a real easy carb to work with - -BUT
yours is older and MAY pose a few issues.

I guess even though I would really like to see you rebuild the carb - I would
suggest going for a newer 4160 - -They will run you around $300.00 BUt
they are basically plug and play.

Keep in mind - -if you do buy a new carb - -make sure it is capable of
handling a Ford automatic kick down. Even if the carb is not set-up for the
kick-down - Holley makes a kit - but that will add to the cost of the carb
Not sure if your car has an automatic or standard trani

My advice - get a new carb - -save the OLD carb - it will have some value to
a person doing a stock make-over on especially a Ford Truck which this carb
was common on.

LASTLY - - can you see where the gas is leaking from? It is possible that the
carb just needs a new accelerator pump. Of course it could need all new gaskets
BUt there is a strong possibility that it is leaking under the driver side front
(where the accelerator pump is located.

Let us know your thoughts and if you see a carb for sale- -perhaps we can offer
some thoughts BEFORE you buy it

This is a typical problem with holleys, when they have had gas in them, an then allowed to dry out, the cork gaskets between the fuel bowls and the carb body, shrink and crack. They are not hard to rebuild, the rebuild kit covers several models, so you have to match up the cork body gaskets (they have many holes) in the kit to the ones on your carb, and then line up the holes to the body when putting it back together, plus replacing the other parts and gaskets like under the screws holding the fuel bowls on. And Print Dad has given you excellent advice. Good Luck.

I believe thats an oem ford carb by holley..a smog carb..if u have no smog on that engine, imo ditch it for a regular old 600 cfm non smog holley..however if you wish to retain emissions on that motor, you will need to rebuild that carb

Thank you everyone for the tips and suggestions, I've decided to go with the 4160 Carb like print dad said after I save up some money. Still need to install the brakes on my 8" and then install the 8" to replace the 7.25 I blew up haha.
