New owner; Mystery Fuel Line

Postby Jyck » Tue Jan 12, 2021 9:05 am

Picked up a 1992 2.3l pickup. Test drove it and it ran well except for an erratic idle however after I brought it home and parked it there was a puddle of fuel.

Does anyone know what this fuel like connects to/comes from? (Attached image) My Weber 32 36 and Holley regulator is on its way but I want to identify this before I start the conversion.

Is that indeed a fuel line, or is it for vacuum? If it's vacuum, does it run a lot better if it's plugged? Where is the other end attached (maybe the fuel vapor canister)? Anything on the underside of the air cleaner it might fit with?
Also, just curious, but what's that steel tubing with the tee-fitting for, along the firewall? R/

It’s definitely a fuel line as there was fresh fuel coming out of it.

The tubing is an air line for the air suspension.

Hmmm...so where exactly is the other end of this fuel line attached? I believe the mechanical fuel pump only has one outlet to the carb, and it looks like it's intact.

Air suspension air line: got it, thanx.
