What is your machine serial number?

This could be a broken supply line but it also could be a restriction within your supply line. Try removing the fuel filler cap, then use a rubber tipped blow gun with the primer bulb removed, to give a few good short bursts of air back through the line to see if there might be a restriction at the bottom of your fuel tank that could be restricting your fuel supply line. This would help confirm whether or not that is the case before taking apart the machine to flush out the fuel tank. You can also use your model and serial number to go on to the Bobcat parts website and access all of your parts breakdowns for your model and serial number machine to see all of the fasteners and guards that are around your fuel tank for mounting . It's a pleasure to help anyway I can.

the air trick did not work. To get at the fuel line where it enters the tank. Do I need to take out the seat and the left hand controls to get at the fuel line.
Mechanic: Dan, Technician replied 2 years ago
Remove the floor plate under the mat inside the cab. It is still a pain to get to but people have been successful accessing through the floor plate under the mat.it wouldn't hurt to remove the seat as well to get extra working space and it doesn't take that long to get the seat out.
