Just a thought, use a 90 and a 45,...screw the 90 in there to get you a little bit away from the scoop, angled to a 45 degree angle, the use the 45 to get going along the fuel line to your rear carb. Run some line past the rear carb, get yourself a chrome fuel (or make a SS one) gauge mounting plate and attach right under the rear drivers side stud where you can see the thing while your driving....I'd even put a bulb in it and wire it up so you can see it at night.
I build motors and tune....that is my speciality, thats what I do. Folks think I'm crazy but there are 3 things I do.
1. I have 2 oil gauges, 1 on the motor where I can see it while tuning and during break-in, the other one in the cockpit, for the driver/pilot.
*On a race car, there are usually only 2 gauges, 1 is a tach, the other is oil pressure. On the nitro and alky altereds, only the oilpressure.
2. I have 2 fuel gauges, I run up by the carbs, looking up and out over the valvecover, so I can see it while tuning. I also have one where I can see it while I drive. (On my street cars, I use only 1, for going down the road).... If your gonna starve a motor, its gonna happen when its reved up a little.
3. A kill button on the firewall, just in case.
NEVER EVER, WHATEVER-YOU-DO, DO NOT RUN A FUEL LINE TO A GAUGE MOUNTED INSIDE THE COCKPIT! NO FUEL LINES INSIDE WHATS-SO-EVER! 1 Spark and your toast!
