Re: Losing Power...Another Update...
So, I just happened to see Vic's video on bleeding the fuel lines...wish I would have seen it earlier...maybe it would have saved some problems...or at least some time. The video is here:
http://www.orangetractortalks.com/2008/11/how-to-bleed-kubota-fuelinjector-lines/
The pertinent section is as follows:
"Loosen off the retainer ring holding the fuel filter bowl in place, so fuel washes over the sides of the plastic cup. Tighten it up, as the fuel is flowing to eliminate an air lock on “top” of the fuel filter. Next, disconnect the fuel line coming from the fuel filter bowl, into the fuel pump. Confirm that fuel flows there. Reattach, and then disconnect the fuel hose coming from the fuel pump to the banjo fitting at the bleed screw on the injector block.
Crank the engine and verify you have fuel coming from the fuel pump."
So as I was following is step by step that he illustrates 1/2 way down the comments section. I determined that:
- fuel was flowing by gravity to the filter bowl,
- fuel was coming out of the filter bowl and into the fuel pump
When I disconnected the line that runs from the fuel pump to where the bleed screw is, I cranked the engine several times to see if fuel was coming out of the fuel pump. What would happen is that I would get a fairly continual drip but it would not "shoot out" as I would expect Consequently, I could see where it would take a long time to get up to the injectors. Is this normal or should the fuel pump really shoot out the fuel assuming its getting a constant flow from the fuel bowl which it appears to do. I just want to make sure I don't have a fuel pump problem.
Thoughts?
BTW, in response to the suggestion above, I did check the radiator and it was full so (fingers crossed) I don't have a head gasket problem.
