Customer Question

Have a Kubota T1570A-40 lawn mower. Motor runs fine for about 15 minutes, then starves out (no gas is visible in the fuel filter). I've rebuilt the carb, replaced the fuel filter (twice), and the fuel pump.

Have you tried a test line from the fuel filter inlet , back into the fuel tank filler bypassing the tank and the tank outlet line? Also be sure the fule tank vent is open, should be in the fuel cap. If tank draws a vacuum, the fule can't be sucked out by the low pressure pump.
