The Nissan Path

I've been looking at the OEM part diagrams and it shows 2 clamp style fuel hoses going in to the fuel rail. However mine has one clamp style and the other has 2 fittings.

Its a 99' v6.

You can see it in this image in the upper left

Sounds like you are looking at a diagram for an early production 99 Pathfinder when you may have a 99.5 model (last six of VIN # -350001 and later). Try the part diagram linked below:

I believe the part you are referring to is the # 16440-2W10A fuel line (pressure side); the return side hose has been discontinued but can be replaced with 5/16"/8MM fuel injection hose from the local parts store, if needed. The pressure side hose also requires a # 16618-10V10 "O"-ring, if servicing.
