the stumbles happen at different speeds and directions of travel

Ok, there have been four stumbles so far, enough to make me not want to test drive, fearing a stumble/stall far from home, in traffic. 1) backing out of my driveway (backed up, turned 90 degrees to...

I have a proven good Siemens MAF, and good Bosch O2 sensors (low mileage) on the X, and all seem to be working correctly (refer to post #63, with pictures of my Torque Pro display, showing MAF, O2,...

The depressor going into contact with the fuel rail Schrader is not adjustable, whereas the end coming into contact with the fuel presure tester hose, is a Schrader valve itself.

It's a perfect...

Follow-up after finding the right-sized fuel rail Schrader adapter

Three years ago, I couldn't find the correct adapter to fit on the Schrader valve on the fuel rail of my M54. Even Andrewwynn didn't know the exact adapter to use, so I found a Ford adapter (also...

I forgot to pull the vacuum hose off of the F-connector, will do that next. No idea why the PO installed new injectors; he may have done it because he was trying to refurb it to the best he could,...

new fuel prssure readings taken (same as with the old pump, 3 years ago)

Just came in after testing fuel pump pressure. Rained yesterday, and my rotator cuff injury made using my right arm impossible, until late in the day, so this is all I was able to do. Even so, I had...

According to the PO, he installed a Bosch 3.5 Bar (50 PSI) regulator with part number*13531436110, because he had a starting problem, with low pressure, IIRC. I asked why not replace FPR and filter...

Here's what I'm thinking: installing a brand new fuel pump, changing nothing else, might've over-powered the aged (possibly bad) fuel filter and new-ish Bosch FPR (since I didn't buy it, nor install...

Thanks Andrew, i might be catching a glimmer of understanding (maybe)- I filled the tank until the pump handle clicked off. The right tank looked to be about 1/2 full when I replaced the fuel pump,...

I'm "lost in the ozone", so to speak

I never opened the left side of the tank, nor did I see the three hoses you mentioned, inside the right tank. Only ever touched the hose that attaches on the top of the fuel pump I replaced.

I'm...

I never looked at the siphon jet, because the fuel pump was so obviously dead (used a Power Probe to inject 12v to it, without movement). Why look further?

On my first test drive following the...

3 questions, for the experienced guys

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...

I'll check the intake boot tomorrow for fuel (coming up the vacuum line?), and use a pump to suck air or fuel up the line going from the F-connector to the FPR. We'll see what comes out.

more work to be done before I spring for a new FPR+filter

No, I haven't yet found the adapter I bought to fit the Schrader on the fuel rail. If I don't find it tomorrow, i'll order another.

Years ago, on 5-11-2022, when I measured pressure, it was ...

I reset adaptations, as advised, then took it out on a 22 mile drive cycle (but mostly stuck in a stop-and-go freeway back-up situation). No progress towards a successful...

I had often thought of travelling around the inside perimeter of Texas (also my state), when I was younger, and I liked travelling more than I do now (confirmed homebody). I mapped it out a long time...

is new pump weak, or is it stronger?

I would think that it's the opposite; my old fuel pump was weak, causing a lean condition (it barely made 50 psi, four years ago, and didn't hold pressure in the line for long). Now, I'm getting...
