Title: AC fuel pump leaking
Post by: CG sailor on September 04, 2008, 05:35:00 PM
I just discovered that my fuel pump on my 36 is leaking through the pinhole. What would be causing this? I have made my own gaskets for this and was wondering if anyone knew were I may be able to purchase a new gasket set. Thanks

On my older car the fuel pump to block gasket is a Victor 24168 (that is an older Victor number but it might cross to something new).

If it is leaking from the weep hole then I'd worry about the diaphragm being bad. Get a rebuild kit from Antique Auto Parts Cellar, they aren't that hard to fix.

As I understand, the pinhole has a spy function: gas shows coming out there when inside a diaphragm or gasket is leaking.

Then and Now is the Internet face of Antique Auto Parts Cellar, both run by Tom Hannaford. I have had good dealings with him.

Talked to Tom the other day. He was a lot of help and my parts are on the way. I highly reccomend using these guys.

Rebuilt the pump and is installed. No leaks for now.  I have a plate that goes to the bottom (between the eng. and fram) but, with the fan blowing in the rearward direction, blows leaks toward the exhaust. My question is - doese someone make a plate that would go between the pump and exhaust? I thought about building my own for protection of leaks. It wouldnt be hard to make and wouldnt have to hold anything up. I could even make it out of aulm.

Not sure what years, but the factory did install a heat shield between the fuel pump and the exhaust manifold for a while. I believe that a fellow in Central California reproduces them and advertises them in the Plymouth Bulletin.

Here you go. I downloaded this from somewhere, probably the P15-D24 website. I'd give credit for it but I don't remember who made this.

I made one for my Plymouth out of aluminum and it works just fine.

I evidently have an original heat shield on my '36 but can't seem to post the picture. The one advertised in the ply. bulletin is a very good copy and should fit the '36. The '36 parts book (generic diagram) shows 3 studs from the pump holding the shield in place with no bolt to the manifold stud, but mine is similar to the diagram posted and has reinforcing ribs and no rear upturned section.  A standard bolt with a small sleeve around it made from 1/8" or so rigid steel tubing is all that is needed to support the rear end of the shield to the pump, with the bolt replacing one of the pump machine screws that secures the diaphragm section.
The shield supposedly helps prevent vapor lock. The original support studs are difficult to find unless part of an existing pump.
Good luck. LR

Jim and lew
Thanks for the info. I was mainly concerned when my fuel pump was leaking while the car was running. It was blowing fuel in the direction of the exhaust and I didnt want the flams! I have rebuilt the fuel pump and thats another story. I thought that would be a wise installation.
