I recently purchased a new fuel rail w/ a sending unit and PRV. Prior to that, I bought a new rail pressure sensor, so the one with the rail, I'll no longer need along with my old rail. Rail is in great shape, and you can probably drill it out for a little more fuel.

I'm aware a new sending unit is around $220 from Cummins. Not entirely sure what a new bare rail is, so IDK $175 shipped for em both. Paypal preferred.
