So I'm working on a vehicle in my garage at the mo, and currently have the fuel lines disconnected.

Might be a silly question, and might just be me being paranoid, but is this safe? Or is there any chance that this could lead to an accidental explosion? Say there was a room adjacent to the garage with another door in between, could an accidental spark or flame from eg. a candle ignite the fumes?

For now I've popped the lines back into their holes (not tightened). There's a bit of air coming in from around the garage door and I've left a window open.

Will that be alright or am I worrying needlessly?

Cheers in advance

This works for brake lines, should do for fuel lines.

Short length of hose that's a snug fit in the tube, long enough to double and kink. Keep that way with a cable tie, or twisted wire, with one end a bit longer.
Push that end over the disconnected line. Voila!

I keep a few on hand, they last forever, but easy to make up if you need another.

Food bag with a zip tie is also a good one to use, if you wanna get fancy put on one layer, twist it then over the end again then the cable tie

Use that method for loads of car stuff at home if you don't want to leave it exposed.. did this on a load of cable connector ends last time I had a loom partially off and was messing about with the coolant system as didn't want moisture in anything

The only thing I'd worry about is if the fuel pump gets switched on and the disconnected fuel line starts wazzing fuel all over the place, so I'd pull the fuel pump fuse.

Otherwise crack on - in my experience after the dribble when pressure is released they have a dribble, after that it won't be messy unless you disconnect them.

Twist tie or an elastic band works just as well as a cable tie and generally easier to remove
