Pulled my washer reservoir to figure out if any of my pumps were functional; apparently they are not. The only one I need to work is the front windscreen- I don't have a rear wiper anymore, and I don't care about headlight washers. Problem is, the barbs on two of the pumps were brittle and broke partly off during disassembly. Any ideas or resources where I can find different sized plugs, say for plugging the extra holes in the reservoir? Another reason I ask for this resource is the previous owner cut about a 1" hole in the roof to run wiring for lights on the rack. Lights are gone now, and I got it half-a$$ed sealed- it's watertight, but looks like crap. Ever see old auctioned-off cop cars with plugs on the roof or trunk where the wiring was? That's what I'm looking for too. Any ideas?

 

Motorola two way radio shop that supports the police cars has those plugs, ditto for siren/light bar installs. Home Depot, Lowes, and Tractor Supply are good source for plastic barbs and plugs and such.

 

In the commercial metal cabinet shops they call them Oops Buttons. Some auto stores have an assortment of plastic caps that you can bond in place or you could find a bolt washer and nut large enough and use that to plug it.
