moroso says..........about vacuum pump?

moroso says that there pump must be mounted on the passenger side, but does'nt explain why. i hav'nt called them, does anyone here know why you should'nt. it will still rotate the same direction.

Mine is on drivers side, works great ..

Had to putz with it to get it working at the suction point to stop the major draw of oil

Don't expect a whole lotta tech from them

been there, done that

I could not suck from the front of the V/C worked ok on dyno but not on the track

Filled the res on a pass, moved it to center/top of V/C now it draws about a OZ' a pass

Mine is also n the drivers side. Dont see why it matters the directions are pretty clear on the plumbing to make sure it is correct, dont see why the side would matter as long as it is plumbed correctly.

Bottom line and I hope Al agrees, you have to fool with it to get it to work on YOUR application

well that good to hear. i mounted it on the drivers side since the pass side is bussy like big dads. i cant in all my life figure out why they say that. i'm at ease now. thanks

Mine has been there for 230+ passes and is still working great. Very busy from the block to the radiator on mine. If you look under the oil filter you will find mine hiding there.

The Moroso tech is one of the poorest there is IMO

I think I know more than they do at this point and thats not saying much !

I got some tips here and from some others and just kept fooling with it till it worked right

My BIGGEST TIP ..

Get a QUALITY gauge to know what is really doing ,just cause it looks like it is working does not mean it is


I watch my gauge as close as the oil, water,etc

Mine was on the d/s.....that just doesn't make sense

My guess is that it originated for turning left in circle track racing.
