[RED92LX50]

On my 92, the schrader valve (covered by what looks like a tire valve cap) on the fuel line is very near the back of the alternator. To install the Electrical fuel pressure gauge you will need to unscrew the cap, remove the schrader valve (pliers will do), then screw in the sender. If you bought the $79 Electric gauge, you will need to get a 1/16 male to 1/8 female brass adapter - if you bought the $180 Electric gauge I think the sender comes with that fitting.

If you have a mechanical gauge - I am not positive, but I think you screw it on over the schrader valve.

Also, the STOCK fuel pressure regulator does not have a port for the gauge (some aftermarket adjustable fpr's do - but Kirban does not).
