Well, I did like Jim suggested, but couldn't see any fuel leaks or wet spots. What I did see however was rusty steel lines, and a compression fitting tucked up in front of the evap unit. Not good. Even some of the hardware on the evap unit is rusty. But I'm beginning to think that the fuel lines are probably on borrowed time (I've replaced them already on my wife's 2000 Accord, along with doing the brake lines), and are just waiting to either start leaking, or my "ham fisted" approach at repairing something back there.
More likely, I'll drop the tank/rear sub frame, and replumb the fuel and brake lines at that time, as it'll be more open in that area to get at stuff. This will be the 5th or 6th car that I've replaced steel lines on, so it's not like it's virgin territory for me. Well that and I already have an idea of what I'm up against since I've already done my wife's car.

 

Well, I thought I'd put an end to my 1457 problem, granted it's 4.5 months later. I ended up dropping the rear subframe out from under it (wasn't as bad as it's made out to be), and changed the fuel tank (I bought it last year). On my car, the rear seam lip was leaking in 2 places. With the pump out, you could see rust on the inside of the tank in those 2 spots as well.

Replacing the fuel tank turned off my CEL, and no codes are present. I didn't replace any lines or fuel hoses, although I did replace a short piece of brake line (LR), and hose, as it was rotted out at the fitting.

In my case, getting the old screws that held the pump/sending unit in place was the 2nd hardest job of the entire job. The first or really hardest part of the job was dealing with the bottom of the strut thru bolt, as it rusted in place to the steel bushing inside the rubber strut bushing. I had to cut it out to get it apart, and I replaced the bushing with 1 from a Toyota that I had here, along with a new 10.9 M10 bolt, and reused the special Honda nut.
There were some things I had to watch for, and disassemble differently, as everything I had seen on doing the job, were disc brake equipped, while mine has drums, and as such requires total disassembly of the drum brakes. The parking brake cable was kind of threaded thru the backing plate (held in place by 2 M6 screws).

Anyway, I thought I'd report what I found regarding my 1457 code, and it's fix.
