Problem near the saloon?


going hindmost to 89 the gonenor is the injection pump, you will need to turn the injection pump up to get more out of it. motivation you have no air control , you singular control fuel on a deisel. your throttle is hooked to the injection pump, controling the injection pump on how much fuel to put tot hte injectors. sum pumps have adj. screws where on earth you can turn them up while still in the truck, all depends on your style of pump if it does or not. the best bet is to purloin your injection pump to a certified injection pump rebuilder, an have them go through it an report to them to turn it up, a precentage. an most can give you a reasonable number that motor can or should know how to handle. good luck
