      Make sure that the filter/regulator you are using is an AC Delco or WIX part.

      this one: SUM-230151. should i not use it? i've read product reviews on Wix, ac delco, & Summit brand, and all have about the same ratings....4.5 stars and about the same failure rate of either not regulating at all or providing too much pressure. seems like i may need to consider a diff setup. thoughts? appears that the ac delco is made by WIX as they have the 33737 part # etched on the unit.

      I would not use it. There have been quite a few fuel pressure issues related to these no name regulators. Summit buys the cheapest part they can find….

      If I was all set up for it I would use the Wix FPR.

      I haven't used one in years since pretty much everything I build now has a fifth gen fuel module and vaporworx controller.

      I've had good luck with the C5 FFR. But I've only used the Wix or Delco FFR.
      Years ago a bought C5 FFR "kit" from Summit. The filter leaked on the outlet side. I spoke to Summit and they sent me a real AC Delco or Wix I forget. They didn't want the old one back so I tossed it in the bin.

      As Andrew and Don have mentioned, use the Wix or ACDELCO/GM part.

      We've tested a bunch of them, and there is a difference.
