Engine/Transmission (1998.5 - 2002) Air dog VS. Air dog II

[telliott]

Anyone know the difference between them, and is the extra money for the II worth it?

The AD I comes with either a 100gph or 150gph pump, your choice. The AD II comes with a 165gph pump and has a pressure adjustment screw. Also the AD II comes with a kit to modify your existing in-tank fuel module for 3/8" or 1/2" fuel lines, and removes the stock fuel pump (in the canister).
