Rust And Fuel Filter

[delsecure11]

I have a 1992 SC400 with a fair amount of rust near the fuel filter, fittings, on the fuel lines, and the exhaust manifold. It had been driven by a college boy on winter, salty roads. I bet he never washed the undercarriage (it is kind of hard to wash it unless you have on a rack or jack the Lexus up a bit). I’m going to apply navel jelly to the fuel fittings, etc. and attempt to replace the fuel filter. I know the fittings are easy to strip!!! I definitely do not want to get any rust or metal in the fuel line {bad for the injectors, etc.} I am really tempted to put a larger TOYOTA type fuel filter on as a replacement.. But I’m leery about getting away from OEM parts. Since this a pressurized line, are there any preliminary precaustious. Any suggestions?

You need to "depreasurize" the fuel system.

Hayes manuals say ... one way is to remove power to the fuel pump and run the engine until it quits.

buy half nut wrenches so you dont strip the fittings.
