Re: exaust noise cutting out and looseing power
seems like you can tap a port on the fuel filter housing , and put a guage out there for testing .
in fact didn't you (charles) run with a temporary fuel gauge out on the hood for a bit...
I know charles has lots of fuel pump failure trouble shooting expierence.
I would pick his brain some more.
