Did exactly that on my 318 Saturday when I mounted the snow blower for the first time. I bought it last year with the blower mounted and did not mark the hoses when I took it off last spring.ducky said:DUD! I have been napping again
If you are pulling back to Raise reverse the hoses and all should be OK.
I bet there are just hooked up backwards. Once you get it correct just paint the male and female coupler on one hose for future identification.
