    Forgive the technical term in the title but as I was swapping out injectors and putting on an adjustable fuel pressure regulator I noticed inside of my fuel rail was corroded with dark spots that looked like rust. Is this normal? If not can I just soak it in some vinegar to get rid of it or do I need to replace it?

    Ethanol is some caustic stuff! 10% mixture claims is BS. Ive learned with lawn mowers to never leave the same gas sit in it for a couple of weeks. Always drain it out for any longer period.

    Not sure how normal it is or what it is but if your fuel rails look that way, I would imagine other fuel component's do too. Is it sludge? Can you scrape it? Maybe its sediment? Just a few idea...

    I'm sure you've got lacquer thinner since you're a do-it-yourself body/paint guy. Soak it in that then shoot some air through them. Don't let the rubber crossover piece touch the thinner though.

    just looks like surface rust inside of it. I use cider vinegar to strip rust on parts so I was going to start there and work my way up to the methylamine(breaking bad reference)

    Good thinking.

    ...that flew right over my head until I read the parenthesis.
