I bought some Summit fittings several months back and finally decided to assemble them. John (mtrhead79) had some experience with AN fittings so I asked him to help. I think we did a fair job. We will see when I get a chance to mount them and see if they leak.
First John cut the soft lines from the hard lines.
Removed burs in the inside
Filed the outside smooth
Sanded to new clean metal
Put the old line into the new fittings
Compress it (note rag in vice to keep from damaging fitting)
Cut hose to length using brick cutter
Put fitting on hose
-oil inner fitting prior to install
-protect fitting from vice
-use aluminum wrench or tape up wrench/fitting
Note - put tape on hose at the back of the fitting to be sure it does not "walk" out of the fitting
Assemble had and soft lines
