    While plowing yesterday I noticed on the bottom of the pump where it mounts to the frame it looked like it was leaking from one of the bolts that attach that mount to the pump ( next to the drain plug) the bolts weren't 100% tight but they werent loose either. Do those two bolts go into the tank? Seems kinda silly that they would, is there a gasket between that mount and the pump or something?

    So I just took a look at it in the daylight and a few hours of sleep, I can't really tell if it's leaking from the bolt or between the bottom of the pump tank and that mount or whatever you want to call it.

    Edit: so i just took a look at my manual and I guess what I'm talking about is the base lug cap and I see it has an o-ring in there. So now my question is is it leaking from the bolts not being snug or from the o-ring? And why does that even need to be connected with the tank so fluid can enter? Is it simply to increase the volume?

    The base lug has a little dimple in it, I am guessing that is used for sludge or dirt to settle, but I would suggest maybe replacing the oring. I had replaced my base lug a year or so ago just for the heck of it when I tore my pump down to clean it.

    Im pretty sure its leaking from one of the bolts, do you know if they are tapped all the way into the tank?

    also there is an o ring under there that may be damaged

    I do not remember if the bolts through to the tank unfortunately I took it apart 2 years ago. I do believe that o ring groove in the base lug comes real close to the screw holes, best bet is to just pull the pump and remove it, I had to cut the bolt to get mine off, also the bolt on mine was seized to the base lug
