Fuel System upgrades; Need help

I currently run a 4.2 with a carb. in my 88 YJ. I am doing a 350 swap soon and I know that Ill need more fuel pressure for the MPFI.

Carbs run about 8#....MPFI takes 45-65#.. Would the stock hard fuel lines handle the pressure?

Also, If I could just replace the in-tank pump that would be great. I dont want to replace the entire sender. Anyone done this before and know of a good fuel pump replacement that would give me the pressures Ill need?
