The FSM says there is one the dealer can use that hooks up to the stock fuel line or one of the rails. Is there one I can rent from an auto parts store or something to test it myself without buying the adapter to hook up a sensor?

 

Nissan said 125 and Infinti 135 just to take off 2 bolts and plug in the tool. That's more than a fuel pump kit or the cost of parts to be able to test it myself.

 

Here ya go.

None of those seem to work with the stock fuel line. Seems they all require a port.
