Haven't updated in a while.  Unfortunately the progress has slowed as I work on fixing little things here and there.  Lately I have been working on replacing the cracked-up radiator support.  With that, I have been cleaning up every little thing that is mounted to the radiator support!  This is time consuming!!!

This weekend I found the correct charcoal canister bracket for my crew at the local pick-n-pull.  They had an '89 suburban there and the bracket looked correct.  My truck never had the bracket and the charcoal canister was just laying at the front of the driver's side wheelwell.  Last night I drilled and installed (3) 5/16-18 AVK inserts to mount the bracket, as my aftermarket front fenders did not have the weld-nuts to mount it, but did have one locating hole for the bracket.

For the fuel tank lines I make them the same length as they can get kinked when looped. Neighbor tried that on his TBI truck and burnt the TBI pump up within a week (AC Delco) It makes it a pain to remove the tank, but it's not any worse than before.

As for the switch valve, it should be fine unless you run more pressure.  Most LS run around 52 at the regulator.
