		There is no lift pump in a XUD. There will more than likely be an air lock now, does the grenade get hard once pumped up?

		So i checked the bleed nipple when i got home and everything is all tight!!
The grenade had emptied the diesel out again so i pumped it up till it was hard only when i let go i could hear a very faint noise like air was being sucked in!!!

		I think the Grenade has had it so i have ordered a new on and some new Fuel hose aswell. 
Lets see if that sorts it. it sounded like the air was being pulled in through the grenade so i susspect a little pin hole or something
