Dave,
My set-up is exactly the same as yours, with the two pumps as per Europa and
I have the same pressure rise with the second pump on. I always have both on
for take-off and landing as per the manuals. Works well!
Sue and Bill

Graham,
Haven't decided what to do with this static situation, but I like the aluminium
elbow like you helped install on Paul Macs a/c. Poor old bugger is Mac, with
his Achiles tendon. Did you hear about that??? Any news out of Andair about my
internal filter element??? I am going to send you that money too, haven't
forgotten, just sorting it out with Kingsley when he beams it over.
