where is the best place to hook up the fue pressure sendor for my fuel pressure guage?

 

the best place is to tap in to the fuel rail on the drivers side. theres an AN fitting that you can screw the sensor into and run your lines.

 

so you have to tap and drill on the fuel rails? there is no fitting you can just buy with out tapping?

 

anybody got pictures that would be helpful. Thanks

 

There is a schrader valve that you can use. Since you fail to post what engine you have...
On the LT1 it is at the back center of the fuel rail.
On the LS1 it is at the front driver's side. It is a -4AN or 1/4 NPT male fitting.
You also fail to post what sender or gauge you are using, so...
Most are 1/8 NPT. The sex will vary. So you will probably need an adapter also.

 

ls1 with stock rails and they are prosport guages and the fuel sendor has a 1/8 male fitting on it.

 

I have the fittings in stock $13.50 *gauge is extra
