I just bought a mallory 3 port off the internet and I can't tell which port is which? It's not marked. All I know is that the thing has 4 ports around in a circle, one port on the bottom of the thing and one 1/8" fitting that i'm assuming is for fuel pressure. Anyone have mallory instructions or can figure this out for me?
Which one is bypass and how can you tell?

Thanks again
Steve

 

ok i was flipping around online and this is what i found ........is this info correct??

Well, it says the bottom port is the return, all four corners are inlet and outlet, in whatever way I want(i'm only using one in, and 2 outs(nitrous and carb), I'll block off the other port, and finally that little 1/8" port is actually for vacuum, or boost, so i won't need to hook anything up to it....


sounds about right? or was that wrong?

 

That's how I have mine hooked up, bottom is return, vacuum thing plugged. Seems to work fine.

 

ok that's what i figured, thanks for checking though
