What a dummy, it was raining and I think I left too many parts in the engine bay when I slammed the hood shut for the night.

I have not even bothered to take off the bolts to see how it works inside, but am having trouble finding any of the online parts stores list my pump when I pull up my vehicle.

Can I somehow unbolt the top and just buy whatever I broke?  Or maybe its possible to rig something up from the hardware store?

Here are some pics.  Thanks for any info!

Same thing happened to me. I went to the hardware store and bought some plumbers epoxy. Its gray in color. Cleaned everything around the area. This stuff has the consistency of clay. Unhooked the hose and used this stuff to reattach the broken piece being careful not to get any on the parts inside. Let it completely dry, reattached the hose, then drive to the store for some beer. ;D

ive seen people just thread the plastic, and twist in a brass hose barb. they just 86'd the check valve in the vac pump lid..

Isn't there a check valve up top with branches for the small vacuum lines?(I broke those nubs off as well in frustration)

That thing down below is a check valve or is it more of an oil splash guard?

I was going to use a hose from the upper piece near the brake booster line, then shove that inside of a hose that will accept it and that I can stretch onto the metal plate and put a clamp on it?  Not a ton of room there but maybe it will hold?

I was just kind of weary of getting another old pump after seeing how thrashed mine was inside with a rubber rip on that very small flap.

I never noticed these things were that brittle until I broke it.  I yanked that thing out of the engine a bunch of times and never got a hint of it breaking :)

i would take the top off the pump, drill the check valve out of the unit, and thread in a brass/metal/plastic hose fitting.. it would be WAY better then ghetto fabbing it in the manner you describe. and wouldnt take much longer. may even take less time.. cause you know your gonna have to re-attach that hose to the ~1/4" of check valve sticking up off the pump..

doesnt matter if its an oil guard. air is entering thru that port, not leaving.. so the oil will be contained..

Interestingly ALL my 1.9 engines shipped from Overland had that barb broken off.

I took the top off and 'borrowed' a barb from a 1.6 rotary pump and swedged it in place (rolled the edges over using a ball bearing).

I like the idea of threading in a barb, and leveling off the back side (smooth surface).

You could also 'Braze' a barb in.  There is not a lot of meat, but I would TIG weld a pipe fitting or flange on before I would buy a new pump.

you got it, make sure it either isnt sticking thru, or file it down once you get it finished..

So for the most part the check valve isnt going to be nessesary? Just fit in a "straight through" barbed fitting for the hose and thats that?

theres a check valve on the brake booster

and a check valve in that vac distribution thing, thats about half way down the line, and has about 4-5 hose connections on it.

and then theres a check valve in the pump..

HONESTLY NOW! how many check valves does one need on one vacuum line?!?!  :o

the check valve on the brake booster should be more than enough.  8)

I am going to put one inline close the vacuum pump just for the heck of it and do the tapping of a metal fitting thing.

I was wondering how oil gets up there during vacuum and happened to be running the car on the driveway and oil did splash up enough with the fitting to leak down on the engine and whick to the ground.  So not sure under which condition but there was a good enough mess after a short period of time to make me want to run that check valve closer to the pump.

Easy turbo, I was just making sure I was understanding it clearly. Thanks for the help.
