Answer 1

Go to your local parts store and pick up a can of PB BLASTER unlike most other rust busters PB BLASTER will creep it's way into the rusty area and loosen even the most severely rusted connections.

Answer 2

Use the WD-40, and the right size socket wrench. Tap the bolt as you apply the pressure with the socket. That helps get the oil back in to the threads where it is binding. Works most of the time. Good Luck.

i'm positive it is speaking about hose clamps. maximum gasoline-line hose clamps have a a million/4 inch head which is also grew to change into with a screwdriver. they're really basic to over-tighten. they don't pick a demise-grip, truly comfortable and they are going to be fantastic. If it is an inline clear out, you could don't have any problem determining a thanks to interchange it. it is self-explanatory, and under no circumstances mind surgical operation. If it is an unusual application (which maximum are at the moment), purely pay close interest to the former one once you eliminate it and placed the recent one interior an similar way. gasoline filters are seldom bi-directional. you should placed them in so the gasoline flows contained in the proper route.
