Those of you who have cowl mounted gauges...
« on: July 07, 2007, 01:59:36 PM »

I have 3 gauges mounted on the cowl. Fuel pressure, vacuum, and, volts.

How did you run your wiring/tubing from the gauges into the engine bay? Now that I have a hood it seems to have become an issue. I've been thinking about drilling a hole into the cowl vent area from the firewall and snaking them thru that way, but two of the gauges will need rather large holes for the tubing and that will look crappy as it comes up thru the cowl vent slots. And, not really wanting to drill a hole, I was hoping to find a better way.

If it was my car, I'd mount the fuel pressure gauge inside the engine compartment and then I'd mount the other two inside the car. I've never been a big fan of mounting gauges on the outside of the car. Just my opinion though.

I'd rather have them inside too, but I don't plan on buying an isolator so I'm still looking for ideas. I picked up these gauges for $5 at a swap meet last year and figured I may as well use them. I mounted them one day because I was looking to do anything other than trying to figure out some wiring troubles that had been kicking my ass for quite some time. I may decide they need to go if I can't come up with a decent solution, but it sure would be nice to see what the fuel pressure is doing while driving. (I already have a regulator mounted pressure gauge.)

Autometer offers fuel pressure gauges that use an electric sending unit, instead of an isolater if you prefer.  If you decide you still want to run the mechanical gauge on the cowl without an isolater you might have problems passing tech, because you will have a pressurized line of fuel hanging between the engine and trans.   Midnight Special or one of the other guys thats up to date on all the safety tech stuff could tell you for sure.  That rule might only apply if the gauge is mounted in the passenger compartment.
