Fuel source ?
So I was thinking of spraying my car in the near future and was wondering how to solve my fuel source problem. I have a carb on the car now with the stock 305 TBI pump still in the tank. I was wondering how I could get fuel for my nitrous solenoid. I really don't want to drop the tank to replace it with a better pump, but wouldnt really mind having to put a manual pump on the motor. If anyone can give me some insite on this I'd really appreciate it. Thanks

What fuel pressure regulator are you using? My Mallory has provisions for 2 fuel lines - one for the carb and the other for the nitrous system.
I don't know what the limit is for the TBI pump but I know it'll move a lot more volume at 6 PSI feeding a carb than it could at 12-13 PSI feeding the TBI unit. I'd probably do an in-line booster pump rather than going through the hassle of dropping the tank (unless the in-tank pump was completely dead and needed replacement anyway).

use a carbureted style bypass regulator and plumb both into the same fuel system. If you're worried about (or run out of) fuel flow you can always upgrade to a beefier pump in the tank, add an inline pump... anything that the FI guys do.
If you want to run a more traditional carbureted setup then I would suggest dropping the tank, replacing the stock pickup with a carbureted type pickup and possibly a second one for the N2O. I would probably run 2 pumps and 2 regulators at that point, one for the spray and one for the carb, or a oversized carb pump and a similar setup to the one with the TBI pump.

I think I'm just going to be stuck dropping the tank to replace the pump. The pump has a lot of miles on it and it's barely enough to supply the motor with the fuel it needs, let alone adding nitrous into the equation. Right now I get a steady 6 psi using my holley regulator. I can open the regulator up all the way and I cant get over 7 psi.
