Where can I put a fuel pressure gauge on a stock lt1 fuel system
I bought a roller that was a race car and it had a fancy fuel system on it but I'm going back to stock and still want to hook up the fuel pressure gauge. What is the best way to go about this? The sending unit has threads (1/4" or so) where you can screw it into something but I'm obviously going to have to make something for it to work. Please let me know the best solution. Thanks

Remove the plastic cap from the Schrader valve (hardline, into the rear of the passenger side rail http://shbox.com/1/fp_reg.jpg ), remove the valve core from the Schrader valve, as noted in the post above. Attach a -4AN female x 1/8" NPT female adapter, or a braided S/S hose to the valve using a -4AN female fitting. Run the hose to the electronic sending unit. The sending unit will usually have a 1/8" NPT male thread, so your hose has to have a matching 1/8" NPT female fitting on the other end.
I have found that the best thing to do at the Schrader valve is to use an NOS #17585 -4AN 90-deg swivel fitting. That allows you to point the connection to the side, rather than straight up, and allows you to tighten the fitting aiming where you want it, without trying to over-tighten it on the valve. The valve is only swaged on the hard line, and it is very easy to break it off with too much torque.
I had a 1/8" NPT bung welded to the passenger sied rail, and the sender is screwed directly into it. But that's overkill, unless you have some other reason to rework the fuel rails.
