RHARVEY, JJRSMP12 was referring to the Amsoil DUAL remote bypass system (BMK-15 for the Cummins powered Rams), not the add-on single remote bypass (BMK-11 as you stated). I purchased the optional 90 degree fittings from my local Amsoil supplier prior to the my installation as I wanted the flexibility to be able to install the kit as I wanted. As it turned out I decided to custom make a pair of Aeroquip Teflon/braided stainless steel hoses using Aeroquip steel fittings for my installation.
JJRSMP12, if I remember correctly, the optional Amsoil 90 degree steel fittings are just add-on fittings. . they do not replace the supplied straight fittings.
