Between Omaha and Des Moines, 7 miles South of I80 | tw5 - 10/17/2021 20:31 futtery miss with white smoke this is intermitant changed filters cleaned sediment bowl screen screen in fuel tank tank air vent doesnt use oil water level in rad is constant injecters have been serviced with new tips and pressure settings checked fuel additive in use for more lubrication _any ideas?
Did you clean the screen, for the sediment bowl, under hand primer pump (Assuming your injection pump is similar to my 6620 Sidehill turbo style engine )
Be nice to know the fuel pressure, from transfer pump.
Might have to "Jerry-rig" a way to add some clear hose, to the return fuel line, and look for "Sucking air" or Combustion-gas bubbles, too. ( if you found bubbles, then a person would have to add a second clear fuel line, BEFORE the injection pump to determine if "Sucking Air" {from the fuel supply circuit} OR is it "Combustion gases" [found a faulty nozzle]
Remember, anytime you add a length of clear hose/line to a fuel system (for trouble-shooting) that clear hose needs to go "Uphill" for a little stretch so you have an area to look for bubbles or solid fuel, going upward, thru that clear hose. |
