I took my failed GM OEM pump to bits to see what broke. It APPEARED
to me like the fuel had free access to the armature and brushes.
I saw nothing in there to prevent gas from getting in. BTW, failure
was due to 1 of the 2 plastic rotors being split. Brushes were 50%
worn down after 120,000 miles. The Mexican pump I replaced
it with (AutoZone) lasted 2 months. So I now run the Mallory
4060FI external in-line (having lost the desire to drop the
tank again)    Steve
