/6 headers

Don,
You need to learn the fuel line modification trick.
Your gas line/filter right next to the header heat is not good.

Here is the trick:
Come off the pump,with the filter right behind the alternator.Alternator blows cool air on the filter,keeping gas cool.Come up and over to the carb.
Everything is kept away from exhaust heat.
If you are running a stock fuel pump (non-adjustable)the fuel pressure gauge is overkill in my book.But to each his own.

Have fun !
