Fuel Sender Nut Size??

[jimmycakes401]

Went to put the fuel sender into the tank so I can pressure test it, but I can't find the nuts in the pile of parts I have. Can someone tell me what size they are so I can pick some up at the hardware store. Is there usually lock washers or does the rubber gasket provide enough pressure? thanks!

For those of you not familiar with my situation. The PO ripped apart the car and handed me a pile of parts when he gave it to me.

I think I might have them in SS. If I do, I'll throw them in your box I'm sending out tomorrow. I'll pm you if I have extras.
I think they're 4mm. I'll make sure they fit my tank.

Unfortunately I have to pressure test my tank today.

I do thank you for the help.

Darn. M4 .70 didn't work out.

I think that you need a socket of 8mm to remove them.

I don't have them. That's the,problem. I'm at a store right now trying to find the right size.

They are M4 1.0 I put lock washers on mine.

I used a die and cleaned off the threads. It was the M4 .70. The PO had loaded it with rust prohibative.

How did you get a die within each stud?
Mine are M4 1.0

I just gently turned it by hand. I did not use the die holder. It slide right through the grit.
