I changed the fuel filters (opening up the low-pressure side). Did the usual and used the hand pump and got air out. i think. Tractor runs great but... now the tractor starts hard and smokes for th first 15 to 20 seconds, after that it is fine. If I restart it right after shutoff it fires right up. Injector repair guy says it's a Mahindra thing and need a transfer fuel pump to pressurize the back side of the FIP. They said Mahindra has a fix for this. Has anyone else done this?
