Question Replacing fuel lines - things to watch out for?

So on the advice of the forum (And my old BMW which caught fire) I bought the 3-piece fuel line kit for my 944 Turbo (supply, return, rail to damper).

I've read the instructions and it seems pretty straightforward as a DIY. I've done basic work like oil changes swapping wheels but not much more complicated than that.

Any tips from folks who have done it?

Just take your time. Any spilt fuel will evaporate fast but you make want to start the car. Pull the dme relay and crank it a few times to get as much fuel out of the lines as possible.

I've found that if you wrap paper towels around the end of the rail and take off the cap, you can control the fuel mess fairly well.

Might not want to fire up the bong while doing the job. Stuff like that.

Um
Don't use an oxy/blow torch to cut lines.
Don't use an angle grinder either.
It's not cranberry juice, so don't drink it.

Use a jumper wire to turn on the fuel pump with the rest of the car off. That way you can check for leaks without any other potential source of ignition.

Um ya I really suggest the 20lb fire extinguisher. I was a paid fire fighter "not volunteer" for 14 years so take my advice and get the fire extinguisher if ya don't have one.

Gas fumes plus electrical spark........you get the picture BOOM

Make sure the replacement lines and fittings do not make contact with the brake lines and also at the clamp to prevent fretting of a brake line or an aluminum fitting.

House around the corner from us just went up in flames last week. (All occupants out safely) According to the news, the homeowner was doing fuel pump work on one of his vehicles in the garage when a spark ignited the fuel. Wonder if his insurance company will be making any efforts to determine if the battery had been disconnected at the time of the incident...
