2003 GTP. So long story short, I'm looking to find strainers for the fuel pump, hopefully both, but I really need the inner. I installed a ZZP350 pump last summer; stored the car over winter, pulled the car out and it ran fine on the E85 that was in the tank all winter, on the first fill up, with about 1/4 tank left car really bogs. I did a bunch of little things to try and remedy it, I ended up getting a fuel pressure gauge and as I throttle up pressure goes from about 39 psi to 29 psi. So I pulled the assembly and took it apart and the inside strainer is sort of concave and sucked into the pump and it is super dirty just by pump, not the entire 3 or so inches that it is. So I'd like to find a just a strainer and not have to spend the $250ish to get a new assembly and pump.
FYI, I tried the local GM dealer the response was that they do not service fuel pumps.
I also tried O'Reilly's and another local parts store.

Any leads would be awesome. TIA
