This banjo adapter kit from Aeroflow allows for a much lower-profile installation than any 90 degree elbow.
The banjo adapter fitting has a standard male 10AN fitting (7/8-14 UNF threads, 37° flare) to accept any female 10AN hose end. The banjo bolt has -10 SAE threads (7/8-14 UNF) to fit any standard -10 O-rinng boss port. Viton O-rings seal the bolt to the adapter and the adapter to your port. To reduce the overall height even further, the banjo bolt has a hex recess instead of a thick male hex.
Clear anodized aluminum (silver-colored finish). Outside diameter 38mm (1.5"). Banjo adapter length including 10AN fitting 57.45mm (2.26"). Height from O-ring 29mm (1.14"). Sold as a set (each includes one banjo adapter, one banjo bolt, and two O-rings).
Note: The banjo adapter seals at the port by an O-ring, but the male AN fitting must seal at the 37° flare. It does not have a shoulder for a crush washer or O-ring.
