Another note, if going to a 3-Line Long Fuel Pump, it would be about 1 1/2 longer (closer to the ground). That is going by Delphi dimensions of 4.5 x 3.5 x 6 inches (Short MF0002) and 4.2 x 4.2 x 7.5 inches (Long MF0055).

Also the Short is 9 PSI (Average Flow Rating/GP of 40) and the Long is 8 PSI (Average Flow Rating /GP of 65)

Not sure if the PSI/GP is any kind of factor at all. I guess these are not 5 PSI since they are 3-line (I swear I read the carb was suppose to have 5 PSI).

Lastly here is a photo, the lines from the fuel take (hard to soft) appear to match up at the correct level for this Short guy. I'd image there would be a downward slop with the long.... maybe my soft lines would not reach properly?
