I spent this afternoon cleaning up and addressing surface rust on the right inner fender. This side has considerably more going on than the left side, so it was a more involved process.
Near the front the single hard fuel line emerges into the engine bay. At that point the fuel continues through a combination of soft rubber lines through the fuel filter and on to the mechanical fuel pump. I started by loosening the hose clamp and removing the rubber hose and plastic fuel filter from the end of the hard line.
Then I used a thin flat-head screwdriver to pry out the rubber grommet surrounding the fuel line hole. I will replace that grommet later.
About midway back was an L-shaped bracket attached to the fender by machine screws. This is the mount for the original glass-jar style fuel filter assembly (which is gone), but as far as I can tell this bracket would have originally been located closer to the front of the engine bay where the fuel line enters. I removed the bracket using a flat-head screwdriver.
Here’s a shot of the place where the bracket was located (note it was about as far back as the shock absorber below) and one of the bracket after I removed it.
Lower on the fender, and further back toward the firewall, there was another hole and grommet for the hard brake line that feeds hydraulic fluid to the front driver’s side brakes. I pried off that grommet also and removed it.
Here’s a look at some of the surface rust on the inner fender, at its worst down low near the suspension.
I sprayed the entire lower fender with Simple Green and used a Scotch Brite pad to clean away the grease and grime.
After a lot of scrubbing the fender looked much better.
I used a 150-grit sanding sponge to sand down the fender, focusing particularly on the areas with surface rust.
When I finished, the fender was much duller in sheen but the rust looked much less threatening.
I used some Metal Prep and a fresh Scotch Brite pad to scrub the exposed bare steel and any remaining surface rust.
The bare metal looked a healthy silver, rather than rusty-brown, when I finished.
