First of all, it wasn't THAT bad; you didn't wad it up or blow it up!

I had the EXACT same problem once. Reset psi, changed regulators twice, changed pump relay, pump switch, re-wired pump/relay wiring, changed carbs twice, changed pumps THREE times...same problem. Changed brands of fuel THREE times, no solution. Pump test? Each time and each pump passed with flying colors? I'm pullin' what's left of my hair out...GRRRRRRRRRRRR. Wife says, you've changed everything but the fuel cell, might as well try that. I do it, all the while thinking she's nuts, but what the heck...

New cell: Problem solved. Turns out the foam was breaking apart and upon acceleration a chunk was covering the sump!! Who woulda thunk THAT??!!??

Cover ALL of the basics first, don't ASSume all components are working correctly...check everything!!

Good luck and let us know what happened.
