Re: Chevy 250 vacuums lines
1] IDK. OEM Fuel Line, 5/16'' maybe? See if it runs from fuel pump, around the head to carb.
2] Upper center screen -- Carb vacuum line coiled, to go to vac can on alternator.
[Replace it, as rats have chewed on it.]
Lower screen left is a broken off electric water temp probe.
3] Looks SMOG-related, A.I.R. system. Delete for performance.
4] Left of the dipstick is the oil pressure idiot light sensor. Right of the dipstick is a cut-
off mechanical oil pressure gauge line.
