Can somebody tell me what this part is? It’s bolted to the inner fender on the passenger side on my 75 Blazer, which was originally a 350 engine. I looked thru the factory service manuals for the heating system but just don’t see it!

Not factory. Looks like a y fitting. Most likely for fuel.

Its part of the ejector seat option.The mystery toggle under the dash,opens a solenoid on a compressed nitrogen bottle,the bottle feeds through the bottom port of that junction,out the top port to the ejector seat. You're missing some components.I know at least a few of our members have the mystery dash switch. You guys need to team up and find the rest of the components.

Whatever it is, I wouldn’t trust anything on a truck that new that’s bolted on with a slot style pan head fastener.

That screw belongs on yard furniture from the 50’s

I took it off today and saw one word on it: Moroso. So googled Moroso and found it. Then tossed it.

Did that have dual tanks at one time ? Probably used to feed two tanks to the fuel pump.
