Fuel injected to carb swap?

Fuel injected to carb swap?
Hey guys. I'm about fed up with my fuel injection, and was thinking of possibly switching over to a carb setup when I drop in my 350. The only question I have with the swap over is what to do about the gas? I don't have any problem with running a mech fuel pump but where was I get the gas? Could I just hook a line up to the fuel feed line that my fuel injection is running on and just turn off the fuel pump? Or wold I have to run a different line and pull out the fuel pump?

The existing in-tank pump is going to be a restriction if you don't use it. It would be easier to wire a switch to the electric pump, and install a return style fuel pressure regulator (absolutely necessary) before the carb.

yes I understand that the fuel pressure is wayyyy too high for a carbuerated application, but I wasn't aware that there was regulators that could reduce that amount of pressure. thanks alot where would I be able to get my hands on one fo these regulators?

summitracing.com, search for a return style pump. You can tap that into your existing return line to the tank. The idea behind the return (as you have now) is to keep the fuel pump running at a consistent rate, with the unused fuel returning back to the tank. A "dead end" non-return style pump will wear out faster because it's actually being "held back".

Alright I found one on summit... http://www.summitracing.com/parts/QFT-30-900/ do you think that will do the trick? and also, where would you suggest mounting it?

Yes, by wear out, overheating (overworking) the motor is what I was getting at. And yes, the gas does act as a cooler for the motor. For that reason, I try to never let my car get below 1/4 tank.

If at all possible, I would try to retain your existing line, with flare fitting in tact. Summit also sells male and female flare adapters/fittings that you can attach to the regulator, and then hook your line to. With a high pressure supply as you have, you want to use flare connections. Rubber hose with clamps is an accident/leak/fire waiting to happen. After the regulator, using a barb fitting with rubber hose to the carb will be just fine.
