Dave,

Check the fuel pump inlet size. If it's 11mm, be sure to get the tank with
an 11mm outlet. Tanks with 7mm outlets going to an 11mm pump have been
reported to cause cavitation and premature pump failure. busdepot.com has
both size outlets.

With a screaming pump, I'll be doing a re-replacement.
