Windshield washer fluid reservoir grommet size?
 

I was leaking washer fluid whenever I filled it up past where the pumps go into the reservoir. So I looked on RealOEM, and ordered a few to replace grommets on all 3 pumps.

However the grommets only fit on the smaller two pumps for the headlights and rear window. RealOEM only lists one part number.

Does anyone have the part number for the windshield washer pump grommet?

You checked the diagram for vehicles without headlight cleaning. The thicker one is for that. Nr.12

Thanks very much!

My gromets were leaking as well. Which fit where & how they fit also confused me so i never ended up ordering. Instead, I fixed the issue by wrapping both the pump "pipe" & grommets with teflon tape. Zero leaks, and doubt they will ever fail again. This was maybe 3 or 4 years ago, if not longer.

That's what I did also for the time being until I get the grommet, and it doesn't seem to be leaking. Good idea.

I have temporary Teflon seal enhancement on about 4-5 o-ring between mine and wife’s cars going on about 2 years average. I've used on the oil filter (that one was temporary), the siphon jet, the radiator outlet temp sensor.
