Done and done =) I neglected to take some "after" pictures because I was too intent on going straight to flow testing the fuel pump, then taking the car for a drive to make sure everything was good =)
I put the new length of 5/16" fuel hose in (I got rid of the 6" double loop and just went with a straight shot from the fuel pump to the feed line) then fired the pump up and checked for leaks. Tightened up the clamps a bit more after spotting a leak and proceeded with the 43.5psi flow test. I was kinda worried that when I cranked the FPR up to 70psi (it wouldn't push higher than 70psi by the adjuster on top of the FPR) but the fuel line held fine and was leak free =)
As for the fuel flow...
At 43.5psi it took 5:42.5 to fill 5 gallons.
at 70psi it took 6:31.5 to fill the 5 gallons.
And my handy-dandy garage note pad..
Please correct me if I'm wrong, but to find the GPH would I divide the time by 5, then multiply by 60? It's been over a decade since I needed to use math for daily questions/problems (I would ask Bianca, but she's worse than Chris at Math..)
