    Did you ever discover the reason for the cracking

    1. Who is installing the fuel pump? You or your mechanic?

    2. Are you installing an aftermarket or OEM?

    3. Did you at all physically match up the new fuel pump with the original to ensure dimensions of set pump were the same?

    And:
    4. Were the replacement pumps labeled Omix-ADA? NAPA still lists a mechanical pump for that application that would no doubt be a way better bet for one that actually works.
