Edelbrock RPM

[Husk Challenger]

Hi guys,

I have to order some fittings to put on my Edelbrock 7576 RPM Air Gap.

Can you tell me the correct NPT size for 1-2-3-4 please?

Thanks!

Thanks but with Covid 19 everything is closed here. I may have a chance to order them online.

I just need the threads sizes of the holes by looking at my picture.

N°1 is 1/8 NPT for my water sending unit
But N° 2 3 and 4?

I know it may be a silly question, i have no problem with metric, but UNC UNF NPT etc... i am LOST

Typically pipe is 1/8, 1/4, 3/8 , order a couple of each
