I need to know the fitting sizes for my edelbrock manifold... i have 2 3/8 thread for my vacuum and one for heater hose, but i have 3 more bigger ones, i think they are 3/4 thread but not sure, right now i have pipe thread plugs just until i get the proper ones...

can someone help me? I would love fittings built into a hose but i guess i wont find those, so I need to have 2 with elbows and 1 straight, are they SAE? and can someone send me a link for them..

also can you show me pictures of how you have them connected.. thanks

post a pic of the ones you're asking about. I would say if they're bigger than 3/8 npt then they are 1/2" npt, which they have for water temp senders, larger heater hoses, etc. I can't think of any that would not be npt threads.

here is the of the manifold, one is on an angle, the middle hole is for the 3/8's thread and last one is the same as the first one, assuming it is 3/4. the last hole is on the waterpump, which is not pictured

[camcojb]

the last hole looks like 1/2" npt, and if the first is the same then it is too. But that pic angle makes the first one look like 3/4" npt, but I have never seen that size used on an intake like that. Should be 1/2" npt.

1/2" and 3/8" NPT.

Vic,
They are not SAE threads, they are pipe threads. Any decent auto parts store should have the heater hose nipples in stock. I think they are all 1/2" Pipe Thread.
