which adapter do i need to install the cobalt fuel pressure sending unit to the fuel rail on my 96 Z28. Here are two part numbers i found from autometer: 3280 and 3275. Thanks for the help

The typical pressure sensor has 1/8" NPT male threads - not sure about the specifics of your unit. The fuel pressure test connection is the Schrader valve on the fuel supply line, and its a -4AN male connection. The solution I prefer is to not mount the sensor directly on the Schrader valve... it can interfere with the fuel pressure regulator, is tight against the cowl, is subject to excessive vibration and heat, and adds a load to the Schrader connection, which is only "swedged" on the line, and expensive to repair.
The NOS part # 17535 -4AN 90-degree swivel fitting will go on the Schrader valve, and can be pointed in whatever direction you want without overstressing the connection. Then get a 24" -4AN braided hose, with a 1/8" NPT fitting on the other end. I have seen these on e-Bay for about $13. Then attach the sensor to the hose. Tuck it away in a safe location.
