1) Was the new fuel pump pressure so much greater than the old pump, that it might've blown the diaphragm in the FPR (allowing/forcing excess fuel forward), or is it just a coincidental thing to installing a new pump?

Though I don't believe in GOOD coincidences, my life history is full of BAD ones, usually coming in threes. For instance:

• a) fuel pump replacement coming at the time I needed to get inspection, and now I'll be working on it for awhile to come
• b) had to bury one of our dogs on the same day, getting poison ivy at the same time...missing the young guy, and hating the poison ivy (I thought it was too late in the season to get it), and
• c) my new (4 months old) phone hasn't been charging for two days, but I finally fixed it, just now...is that three, or more?

2) After looking at multiple videos about changing a fuel filter/FPR on an E53, is there a way to squeeze under the shield/modify it, so that a crippled old man can do it while laying on plywood in his driveway? i would've already done the job three years ago, but it looked to be a bear, and I waited (perhaps too long). Not only is my fuel system paying the price of the delay, so is my body.

3) I understand how excess fuel could cause surging and rich fuel trims, but where does stumbling/stalling/going into a partial limp mode figure in? and only after a sharp turn or a sharp curve? I can't figure that one out.
