I have a 1980 Allmand 31.
Anyway...I want to replace the hoses and rebuild the head on our Allmand.
Oh Boy! First thing we did was to replace our sanitation hoses with our Allmand. Sri..can't remember the sizes..other then remembering the cursing, sweat and blood..
And the second thing was replacing the over head...
