Hey gang,
I went for a smog test and they said that my RV is missing the "back pressure modulator" which I've come to learn is also called the "vacuum modulator."
I had the shop that did the test do the repairs, which I'm not sure was a great idea. They said they ordered the part but what they got doesn't fit bc they need something like the part pictured but with only 2 ports (1 on each side) rather than the 2+1 in the picture. But they can't seem to find one like that.
What little I've found online suggests that the right part is a 2+1 like in the picture. For example, this one on eBay which claims to fit "22R 81-88," or this other one on eBay which says it fits "81 to 83 Toyota Hilux Pickup."
Is the shop wrong? Or am I missing something?
As always, your help is greatly appreciated.
Thanks,
Lenny
