What is this??

[MoparDaddy]

This is on my 90 dodge d250. All I know about it is: 1. There is no visible part number on it 2. It has vacuum lines going to it.

If anyone can help, I would appreciate it.

Looks like solenoids for emission control. Where do the vacuum lines lead to?

Some go to the tbi. I didn't really think to follow the others. I want to say I remember some of them being for HVAC

They would be your Purge Solenoid,ASRV Solenoid and your EGR Solenoid....

Thanks Martin! That diag is missing from my manual. Printing that at work tomorrow!

What does ASRV stand for?

It is missing because you have a POS Haynes generic peice of trash for a manual.

Find an OEM Mopar shop manual set for your truck and it will save you money and time in the long run.

I like Haynes better than chiltons.

Both of them are generic POS that cover a range of years and offer very limited information. Before I got in to the factory manuals I thought they were great but now I know better.
