What do i need to install my fuel pressure gauge? And exactly do i put it? I have the 1/4 inch back mount gauge.
Thanks

 

Are you talking about an under hood gauge, or an in-car gauge? Generally, the gauge will have a 1/8" NPT male connection. Are you sure yours is 1/4"?

You need to attach a -4AN fitting to the Schrader valve (test port) and then convert from there to whatever fitting your gauge requires. I also recommend you do not try and support it directly off the Schrader if is is a large gauge.

 

I know this is an old thread, but I've been researching my question and this one looks like it might help me......

I need a "T" fitting to put on my schrader valve. I think the fuel feed to the solenoid for my nx wet kit has a -3an fitting on it, not really sure, but anyways that fits right on the schrader valve.....the problem is I need a fitting that will also allow me to hook up the autometer c2 fuel pressure gauge sender to the schrader valve.....does anybody have a part number or any info?

 

The Schrader valve is a -4AN.

Put the fitting that I mentioned above on the Schrader valve. NOS makes a part #17535 -4AN 90-degree swivel fitting that works really well, and gets the connection pointed to the side, rather than straight up.

Get a short -4AN hose with -4AN on one end to attach to the Schrader, and 1/8" NPT on the other end to screw into a high pressure brass "T" that you can buy at any hardware store..... 1/8" NPT female on all connections. Screw the hose in one side of the "T", the NX fuel supply connection on the other side of the "T" (may need an -AN to NPT adapter), and the fuel pressure sender "side-out" on the "T".

NOS makes an 18" hose in the -4AN / 1/8 NPT combo, and I have seen shorter ones on eBay for about 1/2 the price of the NOS stuff.
