My jeep check engine light blinks when I go over 70 mph

You didn't replace the PUMP!!! but you were on the right track (-:

there is a high pressure pump in the tank with a strainer sock, also replace the VC (vacuum canister) while doing all that work, it is near the tank at the left rear of the vehicle and replace ANY hose that looks slightly suspect! This IS a lot of COSTLY work.

good luck

Hello,
