Gentlemen,
I am currently putting the finishing touches on the hard lines for a 1965 409 engine which I put in my 1934 Ford Cabriolet. I am having a guy in Texas make some braided steel lines for me, and we are now working on the fuel rail (the engine has dual quad Edelbrock carbs). I have a mechanical fuel pump in the stock location, which will have a billet filter mounted to it, then the braided steel line up to the fittings on the carbs. He is suggesting that I switch to an electric fuel pump mounted back by the gas tank. I wanted your opinion regarding whether the mechanical fuel pump is OK in this application. A couple of points:
1) The engine was built at Show Cars, they ran it with the mechanical pump in place, and said it performed just fine.
2) Everything is already plumbed from the gas tank forward to supply the mechanical pump. It must be a shorter run of fuel line in this car than it would be in a stock Impala, and I see those at car shows all the time running just fine with the stock pump.
3) While I plan to drive this car hard, it certainly wouldn't be any harder than cars run at the drag strip, which have also run mechanical pumps just fine.
Any advice you could offer would be greatly appreciated!
