I used to carry a new ShurFlo automatic demand pump, No. 2095-204-412 in our Autotrail Mohican as a spare. We changed the Mohican this summer and the number on the new van's pump is 2095-204-112, Can anyone please tell me if the new pump we used to carry as a spare, is a suitaable replacement for the new van ?RegardsTerry Birch
