I literally drove it all over with a half tank an observed this fully once it gets to that point.low fuel .did several test runs..if I stop faster it can miss hesitation an stay at 670rpm[only under low fuel in tank]..
I think im gonna put another fuel pump/ module/assembly/unit in it an clean out any trash in the tank.I did use several treatments in tank that may have dislodged any gunk or trash in it.
Any other ideas to look at ,or try , including blow the lines out ?
What is the best brand that's not over high on cost?..
On putting in new how do I know the correct mark to place it at ,I see many putting mark on old one before removing but not sure mine is where its supposed to be before removing it..
Also what's the best technique to use to clean out the tank once off ?
Best technique from my knowledge is siphoning any OLD gas out, then flushing with fresh water for a few hours while you work on trying to find any cracks in the fuel lines. This is a plastic tank, right?
