    hello, curious as to where the vent location is on the mm1 sehp unit. i cannot find one, curious if someone replaced a fill/vent assembly with a plug ? this unit has three pipe plugs on it, drain,fill and a fluid level plug on the side...thanks, bill

    No external vent on a SEHP.

    Just crack the fill to bleed after filling.

    how does the res. draw air into it when raising the plow, if it was sealed it would pull a vacum?

    I always take the motor off to fill this style.. you spend way less time to get it right the first time.. (and no fluid spurting at you)
