Hi Guys,
I'm gonna swap out my Greddy plate for the GE sandwich plate, but I had a quick question. I want to use the GE 1/8 NPT port for my oil pressure and temp gauge. Then the larger port for the feed line. I wanted to check on which fitting I need to for the large port to work with my 3 AN line.
I'm guessing that it is the 3/4" boss to 1/8 NPT, but I wanted to be sure before I order it.

EDIT: also I have some spare male 1/8 NPT to male 3 AN fittings. I should be able to screw one of those into the 3/4" boss to 1/8 NPT adapter and run my 3 AN line off of that right?
Thanks

n/m I did some searching in the archives and saw a post by "GoldeneagleMFG" and it had a pic of the adapter. It looks like the adapter needed is the 3/4 boss to 1/8 NPT, so that's what I got.

-8AN o-ring port to -3AN flare adapter or some combination that gets you there.
Altho, I just realized that you might be able to use a -8AN flare to -3AN flare male union because there's a flare on the GE plate. It's much easier to find a falre to flare reducer than an o-ring port to flare reducer. I'm just not sure if it's appropriate to use it. I've had an oil leak before when I used a -8AN flare plug on it, but I'm not sure that's where the leak was...might not have been on the plate at all.

Well I have a few spare male 1/8 NPT to male 3 AN fittings, so I figured I'd get the 3/4" boss to 1/8" NPT adapter. I already bought it so it's to late to go back. If the parts get here and it's the wrong one, I'll just order the right one from GEmfg.
