Anybody used the hand operated fuel pump on an LLY? The instructions say to loosen the vent screw and depress the top of the pump with your hand. The pump top appears to be solid metal which will not depress. Seems like it could be a cover over the real pump. Instructions don't mention a cover, and to get it off, you'd need to take off a few screws...HMMM....http://www.dieselplace.com/forum/smileys/Ermm.gif

I pushed down firmly on mine yesterday and it did move down. Until then, I was thinking the same thing as you.

I expect you're talking about the primer pump on the top of the filter cannister mount. It's metal and yes it will depress. On the LB7 it's somewhere in the neighborhood of 20 pumps to prime the system after replacing the filter.
