blue chip has it right, the D rings on the side of the injector pump is used to OPEN to BLEED th einjector pump of AIR: something that maybe the problem that others don't realize they are there for. one thing is go to JOHNS'S web site and read all the JINMA info, (the farm pro is a JINMA tractor) bone up on all the maintenance info there!!! it will saive you time effort and help you get to know you're tractor . as haveblue said, Dealer support is soemthing you pay for, farmpro uses 800 number which have has +/- responces, some say it was OK others say long waits and not a lot of helpfull INFO but usually PARTs have been OK to get when needed form them...
if you need help ask away, besure to read all the info on johns site though it may take you an hr or two but it is well worth it. most of the info posted there was compiled by john as given to him by many others and some articals written by others, (myself included!) on HOW TO's and HELPFULL hints as well as Modifications...
oh and WELCOME to the wonderfull world of tractor ownership...
