Found this issue this weekend. I swapped the fuel pump out of my racecar (Walbro 255) which is obviously much stronger. Shortly after that was when the car stopped running completely. I checked the fuel pressure everywhere and ended up checking it right out of the pump. Turns out it was only pushing about 20 psi everywhere. Pulled the pump back out and the 2" rubbing hose connecting the pump to the housing complete blew apart right down the middle.
My theory is that the issue we were having before was that there was a smaller hole or tear in that hose which was preventing the fuel pressure from completely building up.
I replaced rubber hose on housing and car is back in action.
