I changed the fitting on the return line from the booster unit from the straight up nipple to an -6 AN fitting. Part numbers and pics are as follows.

For those who didn't know JIC fittings is the equivalent to -AN fittings. 37 degree flare. A BOSS fitting is one that has an O ring boss with a nut that tightens the fitting I used it on the return from the unit to the reservoir. It is pic #4 below which is a BOSS on one end and JIC on the other.

If I didn't mention it before -AN fittings are measured in 1/16 increments. -6 AN is 6/16" and -4 AN is 4/16" and a -20 AN is 20/16" or 1-1/4”. Most -AN is measure by ID, -8 AN is 1/2" hose. Teflon hose seems to be measured by OD so a -6 AN, SS covered, Teflon lined hose is actually 5/16" ID hose and a 3/8" OD so remember to get hose ends for Teflon if your using Teflon lined SS covered P/S hoses.

One important tip is to not tighten up the hose fitting to working pressure spec until you are sure that the length and position are correct. The ferrules can't be reused and are not cheap or easy to get from Jegs or Summit. Hoseandfitting.com has them @ $2.75 each. So just snug it enough to hold the line while you work with it. After your sure it s right tighten it up. The ferrule is cone shaped and holds the braid between it and the nut and when it’s tight it crushes onto the Teflon hose locking everything together that’s what allows the 2500 PSI working pressure and 9,000 PSI burst. You don't want a hose end blowing of on the highway because you tried to reuse a ferrule.

Male JIC x Male BOSS 90 Degree adaptor
6801-04-02-FG - $4.80 this is the adaptor that screws into the return line threads in the booster unit. It needs to be drilled out to the size of the stock straight nipple. I suggest you buy 2 the drill is most likely to break and you will have to dig it out if you can. It’s a forged fitting so use a good bit.
