Needed this to make a new fuel filler hose for an old truck that had no hose available. This filled the bill.
Quality looks great; have not made installation yet.
Only place I could find this size reducer in SS.
Making a '83 F150 flair side fuel hose that is no longer available (anywhere) and needed this product to get it done.   I could have cobbled one together from muffler tubing but this is professional and nicely crafted.
I am very very happy.
Thanks to the techs that helped me out with suggestions too.
Nice part, Well made , Fast shipping
