and also 2 a piller gauges, maybe a tach on the dash too. But im mainly asking about putting 2 gauges on the cowl.

you can not put NOS preessure units in side the interior of the car it is a fire hazzard -- they have to be mounted on the wiper panel or hood skirt -- and correction the fuel pressure can be mounted inside but you will need a diaphram one side fuel the other that goes into car or hood area has anti freeze in the line -- but most just mount to cowl -- and bulbs to go to HL switch -- jz

Or you could buy the electronic version of both gauges, and safely mount them in the interior.

For a ton of cash LOL. But that is the best way.

To mount them on the cowl you can just run the wires up through a cowl passage (or make one). No big deal.
