Fuel line... metal line specifically

[bwanac]

Recently I took out my A/C which was equipped with what I found to be called a "fuel cooler".

Now I have to run a fuel line from the FPR, to the metal lines under the intake. The problem is that I cannot get the old one off of the metal lines. Is there some kind of lip, or something that holds the line onto the metal line? I got the screw complete loose on it, but the hose won't come disconnected!

HELP!

It's probably fused on there from the heat and old age. The safest way is to just twist and pull it until it comes off. The easier, but less safe way is to carefully use a straight edged knife to put a slit in the hose and peel it off. If you choose the second method BE CAREFUL! you could cause a spark and start a fire.

naaah... slip & cut yourself, yes... but spark?... highly doubtful, but i guess it's one of those one in a million chance things that you don't really wanna test

with that said... i'd cut it anyway 8) just use a razor so you dont have to use alot of pressure... the only way i see a spark happening is if you used a dull knife, requiring alot of pressure... you slip, hit another piece of metal & that causes a spark... use a sharp enough knife & it won't require alot of pressure

like the old addage goes... a sharp knife is a safe knife (and its very true)

fuel vapor is much more likely to ignite than liquid...

... especially considering gasoline in liquid form doesn't burn 8)

I guess I should have elaborated, so I will now. I can say that I knew that, and am glad to see that others do as well. My dad is a Chicago firefighter, so I've been taught about fire and the bad things it can do since I was 5. Fuel vapor would most likely be present in this situation since the fuel system is open. I agree that a spark is unlikely, but it could happen. Even if a spark did occur it probably wouldn't ignite the vapor. But it could! The point was that it is important to remember to be careful when working around fuel. Actually, it's important to be careful when working on any part of a car. And for the record I'd cut it too, following the sharp knife advice of course. 8)

there is no way a spark could happen from carbon steel knife edge cutting through a rubber fuel hose into an aluminum or ss fuel line...
slicing lengthwise is the age old techinque for removing bound rubber lines..

Carbon steel doesn't spark against aluminum. IN very very rare cases, SS can spark against a carbon steel but only under very high impact loads.

NO NEED TO WORRY

if you wanna use the hose again, shoot it with some WD40 or PB blaster and work it around, it'll come loose.
