I have my articles crossed on this and will find it.

Correct! I was wrong and you are right. The GMC/Chevy CP4.2 sucks gas out of the tank without a lift pump. However the CP4.2 has the other issue of not getting enough lubrication that eventually leads to its demise.

Thank you for correcting me!
