Comment ko lang about that option mentioned by Speedyfix (no offense ment ha).

Me problem lang ako with that option (I did tried that before sa lumang oto ng erpats ko)...most fuel lines that you could get in the market are copper lines and not steel.

Even if you can get a steel line, napakahirap nito ibend and flare. You will also need to have special tools (bending and flaring tools) kahit na copper tubes lang. Else ang pangit ng bend ng linya - nakakasuya.

Plus, replacing the lines would lessen the "authenticity" (aesthetics ek-ek) ng oto.

my 2 cents. peace.
