Alrighty. So I purchased one of those fancy pants Nordskog digital fuel pressure gauges. The sending unit has a 1/8" fitting which is not compatable with the schrader valve on the fuel rail. After Dave's suggestion, I purchased one of the Autometer fittings which replaces the Schrader valve with a supposedly 1/8" female fitting. Well....it isn't a 1/8" fitting, or at least a 1/8" fitting won't thread more than 2 turns into it.

So now what? Does anyone know what size fitting can be threaded over the stock Schrader valve? What I am thinking of doing is removing the pin, effectively allowing fuel to flow freely through the valve. So if I can find something to thread over the Schrader valve, and allow a 1/8" fitting to screw onto it...I think I may be set.

This weekend I will probably remove the entire valve and head over to Home Depot in hopes I can find some sort of a match. I'm really asking this question in hopes someone has done this before so I can possibly avoid farting around for hours on end looking for the infamous needle in a haystack.

Gracias.

 

you did remove the valve completely right? Worst case I have the fitting from mine I can let you have cheap... it worked for me...

 

Yeah I removed the valve completely, then threaded in the Autometer fitting. It threaded with no problems into the fuel rail, but wouldn't accept a 1/8" fitting (like I was told it could by an Autometer rep).

What kind of fitting do you have available?

 

I have an electric Autometer fuel pressure gauge. I had to buy the 1/8 female fitting for the fuel rail for the sending unit. I got mine from Steeda and worked without a problem.

 

Was it difficult to completely thread the sending unit into the Autometer fitting? I stopped after about two rotations out of fear of stripping the threads.

 

Yeah it was. It's going to thread in all the way. I can double check for you if you want, but if I remember correctly it didn't thread in very far.

 

So as long as I have some teflon tape in there, and it is threaded about half way in...I should be safe?

 

Yeah, I put some teflon paste on it and it has never leaked.

 

they dont thread in as far as you might think, but i havent had one leak yet...

 

Are you sure the thread type is the same?
