Fuel pump threads

[RootesRooter]

Anybody know what size and kind of threads are on the intake side of a stock fuel pump?

Rootes, Excuse me for asking a dumb question, But, what is the "intake side" of a fuel pump ?

Never mind!!! It finally registered in this olde pea pick'n brain. I'll go look and let you know tomorrow, if that is not too late?

The intake side is the one pointing towards the rear of the car once the pump is mounted on the block...

Rootes, Here's a couple PIC's of new fuel pumps. With and without bowls.

Both have #10 - 32tpi with lengths of 1/2" including the lock washer.

The inlet is identified by the "arrow" under my finger.

Hope this helps

After all of that, I begin to think you are asking for the thread size on the connection "from" the fuel tank to the "inlet" on the stock fuel pump??

Do you mean this connector?



Thread OD is 0.498"
Thread ID is slightly less than .475"
Looks like 20 tpi
Threads appear parallel.

It could be UNF 1/2" - 20

But British Standard Pipe Parallel size 1/4 looks close, too. However, the 20 tpi gauge looked like a good fit on the threads:



And some extra info. Not sure where I found this, though.

Fuel pump fittings


By David Hall


I had a lot of trouble sorting out how to hook up the fuel pipe to the crossover pipe in back and into a Sunbeam Specialties SU fuel pump. A company called Hose and Fittings seems to have the correct BSP straight fittings and is easy to deal with.


For the crossover outlet, you need a female BSPP #1007-08L-04, cost $2.82 each. For the fuel pump male BSPP, use 1003-08L-06, $2.82 each. Each has the compression fitting for the stainless fuel pipe. Visit www.hoseandfittings.com
