What you're looking for is pretty common. I say that because I didn't have to hunt around too much to find a suitable replacement. Of course I can't recall what they're called or where I got them, though!So when replacng my fuel pump and this vent line hose over the last few months, most of the plastic screw holders for the service cover have disintegrated. Are there any usable replacements for these available at parts or hardware stores? Or do I just have to pick and pull old crap and hope they don't turn to dust?
