You could reach through the drivers side vent box to reach inside the cowl so you wouldn't have to cut any holes and run the line to the outer end of the cowl... where they are designed to drain.

when the gauge gets hot it builds up pressure inside & makes it read wrong.

John - you need to find someone that can drill a 0.030" hole in the vent screw in the gauge. That solves the problem. Know anyone that can do that? LOL!

Why do you think you need a fuel pressure gauge mounted permanently to your cowl. I have 4 gauges i can check whilst racing, I do my best Marty Feldman impersonation if I hear a miss or anything out of the ordinary during a run. Fuel Pressure. Oil Pressure. Water temp. Vacuum. these 4 guages are peace of mind for me when racing as before I enter the stage beam, I check the gauges, if the run is going well then I don't look, but i still check these 4 guages when in the braking zone. If they all showed what i was expecting then its the usual checks between rounds, if not, then i have some investigation to do. I don't consider these dead weight, to me they're insurance.

People like what they like and there is nothing wrong with that. I myself have never cared for the gauges on cowl look. I am very minimalist on what I want on a car. Oil and water are fine and you need to be consistent on water temp at staging, but that's about the last guys look at them. Oil is one of those things, that maybe you need and maybe you don't. If you look down and the pressure is low mid run, the damage is likely done anyway. You could get by with a hobbs switch that killed the ignition or turned a light on. If you lose fuel pressure, the worst that will happen is the car lay over. If you have a shift light or an auto shifter, you never use or look at tach.
I am just a freak about weight, so I hate adding stuff I never use........but that's just me.........LOL!!!
Plus, with the cost of tachs, gauges etc these days, you can buy a RacePak monitor only dash and see all you want to see. Can even get a "replay" model that will replay the run, no logger required.
I actually have the UDX "Street" dash in my gas burner dually. Speedometer, odometer, tach, voltage, water, oil pressure and temp, fuel level. Plus it also has indicator lights you can wire for turn signals, high beams, low pressure and high temp warnings. It's 600 bucks and weighs 1.3 pounds

On our 70 Road Runner,we used a small piece of sheet metal in the shape of a "L" mounted to the screw holes where the washer nozzle hoses were. Then mounted the gauge to that. Ran the line down the lip under the cowl and to the carb.

Monte, I'm actually looking at doing gauges and had thought the price point was much higher. After reading this I went to look because it would make sense to me to have the digital dash for my cars purpose. I went on the Racepak sight and I'm not sure which one you are using and I didn't find any that would do what you said for the price. Could you provide a link or more detail? I don't want to hijack and can move to a new thread if need be....

Ok, it's an A body not a B body but maybe it might get you thinking. I don't have wipers so I recycled the hole, but if you used black nylon Racehose you could squeeze the hose thru the fresh air grille. That fuel pressure reg location ( fire wall) won't pass tech where I'm at. Again, lots of 90* fittings are not a good thing in any fuel system.

Years ago I installed 2 of them on my cowl. One for the carb and one for the nitrous. I knew I did not want to drill my hood, so I made a aluminum plate with rubber glued on the bottom to mount them to. Here's the original car they were on for 20+ years. I used steel brake line and went down through the cowl vents in the hood. Transitioned to braided steel flex line to the carb supply inlet in the cowl under the hood on this E body. Then 20 years later while really driving a lot on the street I noticed too many negative responses. Just the way the cops would look at the car mainly in passing. I got tired of them too, I knew what my fuel pressure was. I have been looking at them for 20 years. Took them off and it has been much better on the street, not near as many looks from the cops and what feels like is more respect. Plus I take the car out of town on many vacations and did not want it to stand out to the local cops. It helped a lot to blend in more. The car already stands out on it own, don't need racey stuff on the car to be noticed anymore. Guess what? No holes or marrs on my hood when I took them off. The lights in them were wired to my running lites, looked cool at night. I custom soldered and shrink wrapped all the wiring and it was done right and for a lifetime. Too bad I took them off! How I transitioned over to #3 braided hose from steel brake line. This is the inlet adapter on my gauge to accept steel inverted flare brake line which is skinny enough and would pass thru the slots in my hood. Then I installed the flare nut and double flared it. South San Francisco and the Pacific ocean with no marks or holes on the hood. Less looks from the cops=win!

cool, looks like I'll be removing the wiper linkage, i never used them anyways in 20 years! I did not use my wipers either for 20 years+ Till the day I drove my car to the top of pikes peak on July 31 a few years ago. It was foggy and 32° at the top. I had to stop half way up and open my hood to adjust the water valve because the cable was loose so I would have a little heat on the foggy windshield. I was praying that when I got back in the car that when I turned that switch that the wipers would come on or else my wife would have killed me. Pretty important to be able to see going up pike peak as there are a few turns with some pretty big drop offs! Didn't think it would be a problem in the middle of summer but I needed them big time that day.
