Schrader Valve on fuel rail
 

Ok guys, when I bought the car it already had a fuel pressure cutoff switch for the nos and had the schrader valve removed. Thinking I might be having pump issues and am going to be adding a tee into the mix. Also very interested in maybe adding an inline fuel pressure gauge so I can monitor it pretty much at anytime.

Any suggestions or should I just add the tee and add another schrader valve in place of the old one that was removed for diagnostics instead of the guage?

I used the fuel rail adapter piece from dynotune it goes on the end of the rail then i put the gauge sending unit off that and u could put you t to that. Or just add that to the mix and put a gauge in. I've been happy with the dynotune guage.

Thanks for the info. Ordered the adapter, but the fuel gauges are out of stock through dynotune. Will be calling them and finding out availability on them. Any particular range on pressure or will 0-60psi be fine?

Ls1's are usually mid 50's so 60 is fine.
