Rebuilt carb on my '69 240

Rebuilt my little carb on the '69 240. Biggest challenge was getting the right kit. Advance showed Carter and Holley as the options and I knew it wasn't the Carter so they ordered me the kit. Picked it up brought it home and tore down and cleaned the carb. When I opened the kit I realized this was the wrong one. Turns out I have a Ford/Holley 1100 series carb, the parts guy had to back up to the '67 model year to get me the right one. Don't think this has been changed as everything lines up too good. Idled ok before but had a dead spot if you hit the throttle. Runs good now and got more travel out of the manual choke. Have a leak at the inlet and can tell the PO had really torqued down on it. Tried putting teflon tape on it but it still drips. Looking at the drawing that came with the kit and it appears there should be a bushing or adapter. So I'm thinking I have a flare fitting line going into a pipe fitting hole that will never totally seal. tnbumper

Put a carb fitting from autozone in the carb that adapts to a pipe, then pipe to SLIP fitting on the carb and convert to rubber hose. The drip could be as easy as a straight thread on the carb with a pipe NPT fitting in the hole.

Picked up a fitting at my local Federated Auto Parts store for less than $2. It converts from pipe to standard thread. This will allow me to keep my hard line without the possibility of 2 leaking hose connections. If you cant find a fitting, just pick up a screw in the carb type filter with a nipple for a hose connection.

We are theorizing the same on the problem and solution, it's pipe thread in the carb and standard thread on the fitting on the line. I found that there are 2 sizes of NPT threaded holes in Ford carbs, 1/8" and 1/4" NPT. tnbumper

Saga continues: Installed the brass adapter fitting and now the carb leaks worse. I guess the PO forcing the standard fitting on the line into the carb rethreaded and now I'm trying to go back the other way is wearing the aluminum thin. JB weld to the rescue? tnbumper

Gasoline resistant RTV and let dry. That will do the trick. Getting RTV, oops everyone calls it Silicone sealer now days ("Room-temperature vulcanizing" (RTV) silicone), wet with gasoline before it sets will stop it from sealing. I don't recommend JB WEld as epoxies expand during the curing process and will be real finicky about how clean a surface is. For the carb RTV must be suitable for aluminum (non corrosive) or the Acetic acid (vinegar smell) that cures the other type will eat most soft metals.
