Fuel rail gauge question.

[TransAm11973]

Thinking about getting a stock fuel rail gauge from metco with the adapter. Can I just get it, purge the rail pressure and put it on? Or do I have to get that tool to get it to work? Anybody done this? pointers? Thanks.

Easy install. Unscrew the cap, cover it with a rag and with safety glasses use a small screwdriver to relieve any residual pressure. Probably very little fuel will come out but better safe than sorry. You then have to remove the valve gut, just like a tire valve stem, before installing the gauge sender.

how do i remove the valve gut?

You will need a valve stem remover. Fairly common tool found at most auto stores.

Basically it is a shreader valve at the end of the fuel rail, same configuration as a tire valve stem.
Wait until the engine is ice cold, so your fuel pressure will be zero.

You don't have to wait. All you need to do purge the rail before you remove the schrader valve.

Or remove the fuel pump fuse and idle till the car stalls out lol
