Thanks =)
Yeah, I'm honestly getting a bit confused now that I'm trying to calculate out my times. I figure either A) I did something wrong, B) I'm doing my conversion/calculations wrong, or C) the practically new 2nd-hand pump I bought is crap from the start =(
Some quick background: I'm at the very tail end of a rather long rebuild/winter build. In the process of the rebuild we went with full AN fuel lines (-8 feed, -6 parallel lines in the engine bay, and a -6 return).
I pushed my FD out of the garage today and pulled my DD up along next to it. I then disconnected my return line from where it would connect to the tank and added another 3' of -6 line to it with a male/male connetor. I then fed that line into a 5 gal jerry can that I had previously pumped 5 gallons into, and marked, at the gas station.
From there I timed filling up the can at 43psi, and then again at 70psi, both times I had my DD running and hooked up to the FD's alternator with jumper cables.
