Default External Fuel Pressure Regulator

I have the UPP fuel system on my car (uses stock pump in combination with an external fuel pump) and want to use the external fpr with vacuum reference. My question is how do I block off the stock intank fpr? Do i just need the 2 items LPE sells? Any advice would be appreciated.

Yup just install those. Block on the driver side, bypass on the passenger side.

Thanks for the quick reply. Do you happen to know how hard/easy dropping the tanks are?

I did mine with the trans already dropped, so pretty easy. The hardest part is hooking the tubes back up to the ports on the in tank assemblies. I have a build thread with a few pics.
