RECALL 25S75 (Ford), 25V455 (NHTSA) Low Pressure Fuel Pump Failure

[engineermike]

So they want to burn out fuel pumps out faster? Let me guess, we get stuck footing the bill when that chicken comes home to roost.

I don’t think it would be a big difference there. The pump runs 65-80 psi all the time so making that 75-80 or just 80 is within the design envelope. It’s just a bandaid fix, if I’m right.

I’ve got an appointment to have my Mach 1 reflashed Friday. I’ll just replace the fuel pump with a DW400 later. This has to be another calibration bandaid.

But this is very similar to how Ford tried to address cam phaser issues on the gen 2 3.5 Ecoboost in the F150’s. They had a reflash to extend cranking time before the truck would fire in order to build oil pressure faster. This was basically to get them just out of warranty. Mine, with the reflash failed at 88k on a well maintained truck. This isn’t much different than GM’s bandaid of oil weight and filler cap on the 6.2’s to get a mechanical defect to limp by long enough.

According to google, software update allows pcm to detect failing fuel pump,
triggers a limp mode so car doesn’t stall, as well as a check engine light.
Pump module would then have to be replaced by dealer.

Don’t wait too long before you take action, because a factory pump failure can happen at any moment.

I got caught completely off guard with no warning at all at one of the busiest intersections in town. Cost me $200 to get towed 14 miles. I did exactly what you’re going to do (install a DW400) after that failure and never had another issue. I did install a DW check valve in mine too, as my DW400 was one of the pre check valve versions.

I’m getting reflashed on Thursday, haven’t had any issues yet.

Yeah the sudden failure worries me thanks for sharing your experience-that’s enough to make me go ahead and order one. I’d hate for it to leave me stranded or ruin a track weekend. I assume they all have check valves now? This is what I was planning to order:

I believe all DW400s come with check valves installed in them ever since 2019. I ordered mine from a vendor that must have had the old version sitting on their shelf.

I just ordered the pump only and modified my factory basket for fitment. You can save about $300 going that route.

got my PCM updated today, we'll see how it holds up now

Same as before the recall, assuming google is correct.

i hope my fuel pump can stay alive, im covered under warranty but would be annoying if it fails
