My TG 1860D bogs down when I go up hill. It's like it's starving for fuel. I've changed the filters, emptied and ghanged the fuel and checked to make sure the fuel pump is working. tHERE ARE 2 FUEL LINES THAT GO INTO THE FUEL TANK, ONLY 1 HAS A TUBE , IS THAT RIGHT? cAN ANY ONE HELP?

Could the one without a tube be a return or vent line?
Might be a governor issue---what happens when you give it more throttle when it bogs? ....

Maybe the fuel tank isn't venting properly, check the gas cap for a blockage. ....

Two things come to mind: 1.) Could be a vacuum condition in the tank due to a clogged vent. Try this: After the engine bogs immediately open the fuel cap and listen for vacuum. If present, either clean the vent in the cap or replace it. 2.) That solenoid is likley the fuel cutoff solenoid. Sounds like it is internally shorted since it takes awhile to heat up which draws more amps then it weakens which cause it to shut off the fuel. Try this: when it bogs immediately touch its casing and see if it is hot to the touch. If very hot, it's probably shot. Alo check for loss of power at the terminal---broken or bad wire at the terminal could be causing short or loss of power to it. The solenoid should be controlled by a relay and this could be also getting hot internally or just not working properly. ....

If it's like my blue, it can't be bypassed as it's part of the injection pump assembly (but the solenoid itself can be removed but fuel would pour out). ....

I cleaned out the gas tank on my British sportscar and I was amazed at the amount of bugs (dead beetles) that were sitting on the bottom of the tank. I mean are bugs attracted to gasoline? I can only think that the previous owner must have had the tank sitting on a shelf allowing bugs to crawl around inside. I cleaned the tank out because I was experiencing sporadic shutdowns of the engine while driving. It was a loose washer from the float that would occasionally drift over the intake pipe and get sucked onto the tube causing fuel starvation. ....
