what's the goo due to?
So I am fascinated how my fuel pump damper and hoses turned to black goo. What the hell could make gas do that?
Kay is a red 1990 K75 with an unimaginative name which was parked with a full tank for too many years. Sure enough, Kay's damper took a dumper. Strewed black tarry cottage cheese all about the bottom of the pump sump. Hoses turned to goo too. Split screen. Frozen pump. And when I pulled the injectors, I found that even the lower O-rings had melted a bit inside their holes.
So now I have to figure out how to clean dried black tar from inside those injector holes. Need something to dissolve the dissolved. As it happens, I had a bunch of that crap get stuck on the end of a crappy Stanley chisel when I scraped goo off the old snap ring. Figured I'd test some solvents on that. If I found out what dissolved the dissolved, then I'd know what to use in those holes. Stanley has a plastic sheath. I filled that sheath with various stuff, stuck Stanley in it to soak, then rubbed with a rag soaked in same. Tried PB Blaster, master bolt loosening stuff. No dice. Likewise gasoline, thinner, Goo B Gone, Engine Brite. Nuttin. That goo is tough stuff.
Finally figured I'd try some hair off the dog. Fetched the rubbing alcohol from under the sink. Instant Success.
I am excited. Going to yank that clip collar out of the trash, buy some 180 rum, and prove this theory once and for all. It's the corn juice I'm telling you. It's that effing boondoggle jack the price of meat up starve the third world subsidize Archer Daniels Midland lower gas mileage ethanol horse manure. Only thing that dissolves O-ring rubber into goo.
Unmitigated risk aversion is the new Puritanism, complete with witch hunts, funny outfits, and solemn preachers thundering doom. The name of God is changed to Safety; the name of Satan is changed to Lawyer; but the object remains the same: to suck all the life out of life and make you live on the husk.
