Ok guys, recently purchased my new beater-- a 91 CRX Si for 200$. Tank leaks like a BITCH.

Swapped it out with another tank, sigh, but alas the new tank leaks as well. Turns out its a coroded line the frame. I'm not *quite* sure which it is-- but here's the pic from hondaparts.com



I think it might be part #5, but i'm not seeing the little nut that connects to this hard line, and I can't find any other pics online. Anyone have issues with this hardline leaking??

 

i just dropped tank cuz I swapped pumps and i WAS leaking at part 4. im hoping I dont have anymore. hope you get it fixed. most of those hoses are easliy replacable

 

does anyone know the part i'm talking about? Under the plastic "box" cover thing by the driver's rear tire. Its that hardline that goes up to the tank. I think it might be the return line? ick. If that hardline is broken, what do you all reccomend me changing it with? a rubber line??
