Schrader valve question

I am hooking up an Autometer electric fuel pressure gauge and wondered if I should gut the schrader valve and use a 4AN to 1/8"npt adapter to connect the gauge or remove the schrader valve altogether.

Also, take a look at the picture I have attached...do you think I could tap in here to get vacuum/boost?

Thanks!!

Once I get the gauges in, then I need to dyno it and I would like to run it at the track once also. Then we are diving in. I know what you mean about the MSD BTM...I want one!

Hey, how did you hook up your fuel pressure gauge? I am thinking I need an adapter from the Autometer sending unit, which is 1/8" npt and then gut the Schrader valve, whcih is 4AN..... or maybe the the Schrader valve comes out?

PS - I want some pics of your install!!

Re: Schrader valve question

If it's just a matter of untwisting the old schrader valve, and installing the one that came with the kit, just swap it. That's just me though. I am a firm believer on using what the part was designed for. You could do that quicker then it takes to open this sites homepage...

Nice IROC BTW.

OK, I just wasn't sure that I could actually unscrew the schrader valve....thanks for the info. I agree with you on using the designed part for the job. I have had some tell me to gut the schrader valve, so I was confused.

Also, thanks for the compliment!!

Re: Schrader valve question

I used a valve stem tool and removed the inner core of the schrader valve and then tapped into the schrader valve... worked good on two cars...

I used the same fitting for boost too...
