Fuel line work around needed

[Kurt Deschler]

I just replaced the fitting at the accumulator on my 200. Cut the rubber 
sheath back about 1" so you can hold the plastic line better. You will 
need to heat the line up pretty hot, but then it will easily go on the new 
fitting. There is plenty of slack in the line to make the repair. I pulled 
the line out of the plastic clamp to get most of the fuel out and used a 
micro torch to heat the line. A heat gun would be much safer, but when you 
are dealing with a few drops of gas from a 1/4" line the chance of 
starting a fire is low. You should not need clamps and they may actually 
increase the chance of failure. Try pulling the line off the barbs once 
the line cools down and you will be convinced.
