WTH is Scotty Kilmer's problem, anyway?

Its suprising that scotty’s repair worked. 6 mm brake line with a 1/4” splice on it.
A hack.
I watch 1A auto for part replacement tips and its very helpful.
Also north main auto is good for walking through test procedures.

As a stay at home mechanic, and such a wide variety of vehicles on the road it is impractical to buy service manuals or to subscribe to online repair manuals. Starting at $1500/year for online access i cant justify it.
So i study,and learn from other’s mistakes instead. Some youtube mechanics are out if their freakin minds,others dont have command of the english language and others can sure speak a lot of words without actually giving any useable advice.

Neve repaired a fuel control module before,not much on youtube either. Had to use my own thinking cap.
