long crank or no start I put clear line in fuel supply line to pump. When running there is a lot of air bubbles in line. Starts fine with a line in a can of fuel to pump. Any ideas?

Hi greasee,

Thank you for the donation.

There is a leak in the fule delivery line resulting in air being drawn into the fule lines. You would need to move further up the line and install another clear line to locate the source of the leak.

It could be joints, hoses or the filter.
