Still Problems with FUEL

Okay... some of you may have known that i recently have been having problems with my fuel system. Sunday i got a new filter and bought an MSD electric fuel pump. I installed both and the car is running the exact same... i have to pump the gas when i am parked on an uphill and at 110mph i lean out along with in the higher gears at low rpms. Is there anything else? What about the fuel pressure regulator? Please help me!!!

There are fuel pressure settings with and without regulator installed in the factory manual, so I can look them up for you. When is the last time you have your injectors out and cleaned?

Rhinor... i just realized that it could be my injectors. They have never been cleaned in 88k miles. Where can i get them cleaned out at and how much $$?

Just throwing another thing out there. You could have a lot of rust in your gas tank, which is clogging the fuel filter very quickly, and causing it to lean out.

Well that is what i thought too, that my fuel filter was just really old. But my old fuel filter looked fine and when i installed my other one my test drive it felt the same... wouldn't it take a lil while for it to clog?

If you're sure that the old filter isn't full of rust, then I would think that it's ok, and the new one isn't clogged. Get a fuel pressure regulator and clean the injectors, if it still is having problems, then I don't really know what to do, I'm a carb guy, don't know much about fuel injection.

REVIEW!
I need to hold the gas down for the car to start when parked uphill.
Huge delay when i shift gears and floor it.
Lean out at 110mph.
Noticeable loss of power it feels like from my butt dyno.

Could this be TPS? Is there a rich/lean adjuster? ARGH I AM SO FRUSTERATED!!
