I have an 86 lb9. Are rubber fuel lines a safe replacement for my stock rusted-through metal ones? Can they handle the pressure put out from the fuel pump?

 

Yes. but make sure they're made for that application to handle the psi and use the right connectors, (ie heater hose and hose clamps won't cut it).

 

i agree...you will be fine. just get the right lines...they will be labeled something like "high pressure fuel line" or something along those lines.

also, make very sure that you use the correct clamps or whatever. if you have to flare the end of the current line you plan on connecting the rubber line to, then do it. if you can pull them apart...then find a better way to clamp them.

so flaring the end of the metal line and then putting a hose clamp on it would be suffiecient?

 

that is what i did for a while before i put my stainless lines on. i didnt have any problems with it.

Notice how he says "before I put my SS lines on". We didn't say it wouldn't work. But is it safe......no. You can risk it if you are in a pinch but I certainly wouldn't drive around like that much. A leaky coolant hose is annoying, a leaky fuel line could prove diasterous.

 

The flare would help alot. I'd keep a fire extinguisher in the car, though.
Stainless lines (brake and fuel) are available through in-line tube and other suppliers.
