Abandoned lines
I was looking around the underside of my 1970 Blazer and noticed 5 abandoned lines at the very rear passenger side. They are about 3/8" hard line with flared ends. Anyone know what these were for?

Re: Abandoned lines
I would like to know this too......
I assume they're part of the fuel emission system...? The ones on mine still had rubber hoses attached but they were all cracked...the first time I filled it up with fuel...gas started running out of one of them....I replaced all of them with new lines and that stopped the leaking fuel... There's also some funky looking set-up inside the bed, on the opposite side from the gas fill hose, with several lines running up and down on it too?

Re: Abandoned lines
Mine are on the opposite side of the filler neck.

Re: Abandoned lines
I'll have to do a double check but I don't remember seeing that in mine. Could be that they were cut out and I only have the remains underneath.

Re: Abandoned lines
Never seen them, but some may have added Hickey Aux fuel tanks... http://67-72chevytrucks.com/vboard/s...d.php?t=295985

Re: Abandoned lines
Look what I found. Near as I can tell, it's a vapor recovery for the gas tank?

Re: Abandoned lines
That's curious. FWIW I have two 72 K5s, each originally outfitted w CA emissions and neither have similar lines.

Re: Abandoned lines
Maybe by 1972 they had done away with this version....
