TR2/3/3A TR3 Fuel Pump Thread Type?

[1957BRGTR3]

What is the thread type on the inlet and outlet of a stock AC fuel pump on a 1957 TR3?

I think this is what you are looking for. Note that the outlet fitting is a special longer part. Here is discussion from thread:
"I talked to Albert at TRF. Here are the TRF p/n's. He said they buy the compression sleeves from a reliable source, not general hardware store, but did not know the length of them.
>5/16" tube nut is 60142, and 5/16" compression sleeve is TL8
>1/4" tube nut is 60176, and 1/4" compression sleeve is 102729

He said both the tube nut and compression sleeves are the same p/n's for TR3, TR4, TR250, and TR6.
Bob"

p.s. It is by far a good idea to get the tube nuts from TRF and NOT a local FLAPS. The FLAPS parts don't work for the 1/4 inch fitting.

Here is the full BCF thread. Best to go all the way through it to find the correct information:

TR2/3/3A - Can someone confirm size and thread count on fuel line tube nuts [brass fittings]?

Can someone confirm the size and thread count on the "tube nuts" (brass fittings) going into and out of the TR3A fuel pump? I do not have a fuel tap. I have 5/16 inch fuel line going into fuel pump and 1/4 inch pipe going out of fuel pump to carbs. I believe both "tube nuts" (brass fittings) are...

Bob is right I have fixed a number a TR6's do to wrong nut to sleeve If the surface of the nut touches the pump then it is to short and does seal with sleeve. I have seen tape copper washers trying to fix a leak it is just a fire waiting to happen. This is on my GT6 but same on the TR6 and TR4

Ever seen this fix? Yes that is JB weld.

I removed this from a TR3B that I was working on.
