Re: Fuel pump
If you still have the 307 engine in your truck, you could simply change the adapter fitting on the pump if it has one and run a 3/8" line. Fuel demand isn't actually going to change if you still have the 307. Or you can get a 3/8" to 5/15" inverted flare reducer to install the line at the carburetor. Or go to neoprene hose and the proper fittings.
