thanks for the linky, ill have a good look at that at the weekend,
i striped my old one, after i finaly opened it up with the dril and a hammer, there is springs inside and a fine filter, cant see how just one port can block, when i first fitted this head it was the same as now, but i took the side bolt out and let the pump run for a couple of seconds, this cured it and worked normal, but now this is working, ill have another play with it at the weekend and thanks for the offer to have a look at it for me, not sure what to do yet, no rush, will be about 3 months before the van is ready for mot, thats if i can get a mig welder
