Fuel Line Fittings Question

Hey Folks,

I am going to be replacing some fuel line on the Duster and am curious if any FABO members have used the non-flare compression fittings similar to this one in their fuel system?
Earl's Performance Tube Adapter Fittings 165010ERL

I have, and use, a flaring tool but was curious it there are any down sides (other than cost) to using the slip on ferrule compression fitting? Seems like it would be a bit simpler and quicker to do.

Thanks as always and stay safe,
Pat

They will work for a while , eventually will leak from vibration , intended for water system that dont move much , and will shrink the inside diameter of ur line some ....
