91 2.4 Stock Fuel Rail outlet adapter

i'm looking for the exact aftermarket or other source fuel rail outlet adapter to replace the stock FPR with an adapter to plumb fuel line to an aftermarket adjustable FPR. it's the 11mm fitting on the stock FPR ... it can be -6an out or 3/8" hose barb. is the 4g63 fuel rail outlet adapter the same size ? I find tons of them on ebay but with no exact dimensions...

nm...found it..... Fuel Rail Adapter Regulator Nissan RB26 Silvia SR20DET on ebay for 19.99. has the exact dimensions i need.
