So my 92 came with tbi which I have read the stock tbi pump only puts out 10-13 psi. . While mocking up my fuel lines and verifying my fuel pressure guage was working I noticed when priming the pump, pressure would go to 20 psi and stay there. When turning my pump on, guage went up to 50- 55 psi. Why would someone swap out the fuel pump and keep the tbi. Haven't checked if there's a fuel trap door hack in my car yet. Wondering if someone
swapped out the pump for higher pressure one but why keep tbi and if I could get away without swapping in a walbro 255. You guys see any issues with my lines and pressure gauge?

I also dont remember were this part goes on the sniper unit if you can help lmk. Its like a rubber plug/seal.
