So quick question, what is the part number for the 525 in-line fuel pump?
I had twin in-tank 255's and twin in-line 255's before, I am changing them out for 90000285 twin in-tank and want to upgrade my in-line fuel pumps as well.
I am only seeing a Walbro GS396 that is 350lph.
I don't think there is one.
What I do see though is the "Veyron" pump, here:
https://walbrofuelpumps.com/walbro-7-00228-51-inline-intank-fuel-pump.html
On that page they only rate it at 330 LPH and I haven't found a flow vs pressure chart for it yet.
330 LPH is better than 300 LPH which is what they actually rate the GSL396 at.
But without a chart it's kind of useless I think.
Walbro "Veyron" is a little confusing to me at the moment because in the 2019 Radium Engineering article, they measured the Walbro BKS1000 intank pump at 577 LPH and they said it uses the "Veyron" pump plus a controller.

BTW that's a great article to read for comparing the 2 versions of the "Hellcat" pump (the F90000295 and the F90000285), the Bosch BR540, the Walbro F90000274, and some other pumps. All in-tank though.
