stock fuel pump specs 21+

[SnowFox]

maybe im an internet idiot (very possible) But i cant find the specs for the stock GT fuel pump on a 2022. I can find all kinds of specs for a dw400.

anybody know the LPH? and pressure? was there a difference in pump specs after 21?

i google "2022 mustang gt fuel pump specs" all i get is dw400....or i get ads for replaement OEM parts but

7 psi low, capable of 75 psi full boogie, but limited to mid-high 40's I believe.

EDIT: same from 15-23.

Same pump from 2018-24.

Stock control range is 58 to 73 psi depending on the tune. It will flow a lot more than most realize. I’d have to look at a log to get actual numbers but I’m running a Roush truck at 14 psi boost on e85 and the stock pump on an 18v bap and it’s maintaining 66-68 psi.

Nice! I think it was one of your previous posts that got me wondering about it's specs. I recall you saying the stock pump flows better than some might think. It triggered my OCD

I have a compulsion where I need to understand the Delta between things. But I couldn't do that if I didnt have the base set of numbers I'm spec nerd. My porn is Thermally conductive of fluids and materials.

I'll stop there before I ramble. Thanks for the replys gentleman. Appreciated.

Ok, just checked, my 2020 F150 Roush running E85 is flowing a peak of 590 lb/hr at 67 psi on the stock fuel pump and 18v bap. That equates to about 345 lph. Keep in mind that pressure is higher than most fuel pump ratings and also the 67 psi is rail pressure not measured at the fuel pump outlet. So basically this is fuel pressure and flow as supplied at the engine after all the fuel line and filter system losses. This is very impressive for an a reliable oem pump.

That is pretty impressive. It's certainly more than I would have assumed previously by a decent amount.

Thanks for checking that!

I actually have a log where I believe it went well over 600 lb/hr at 65 psi but didn’t log fuel flow on that one.
