The original installation of the mistubishi branded fuel pumps in cars is great and not a problem. the issue is when some cheetah mechanic thinks he can install it inline after the fine fuel filter with nitto tape wiring direct hot tapped into the ignition coil positive wire.
That spells disaster. fuel pumps of this type are installed with two filters, one coarse type and one fine type and also have a dead man switch system to immediately kill the pump when the engine stalls even with ignition on. (e.g car crash)
anyway - star looks like you have bought a lemon, and dont worry about that cross member, either find a replacement or find a lohaar who can make you one. I had a guy make me a replacement radiator support crossmember for my VW Golf, he used the rusted sample and made me a brand new one.
For the engine tilt - check mounts and replace whichever are wrong/torn/worn. No use cheaping out on those.
