Default How to reove fuel pressure regulator on an ls1 plastic tank?

Putting an ls1 plastic gas tank in my 87 IROC, I need to remove the fuel pressure regulator to get it to work with my L98, as I dont have the funds to complete my ls1 swap. I'm pretty lost, anyone wanna provide some insight?

The fuel pressure regulator is mounted in the fuel pump module,
push up on the spring clip the regulator will fall out.

Your question begs another...how it the heck is a ls1 vintage plastic tank going to fit into an 87 IROC? I would think no chance, but crazier things have happened.

It slips right in and uses the same straps. 3rd gen and 4th gen share the same underbody and suspension from the rear seat on back. I have one sitting in my '89 Firebird right now. Although, I'm keeping the fuel module in tact. Why remove a perfectly good regulator just to add one in somewhere else?

The L98 runs on a lot lower pressure than the ls1 does. Therefore, I need to remove the fuel pressure regulator in the new tank such that the one on the fuel rail of the L98 will function. I got it out, do I need to plug the hole that regulator connected to?

Sorry, I assumed you were doing an LS1 swap.
No, don't plug the hole. That is the fuel return back to tank.

No, Do not plug the hole where the regulator was. That is the fuel return to the tank.
