Yea...I'd stick with the stock pump too... they work fine and deliver plenty of fuel.

One modification I have seen though was an inline electric pump back near the tank, hooked to a toggle switch. If the mechanical pump failed, you just hit the switch and you're back in business. Also, if you needed fuel for something else (helping someone that ran out...or...), you just pull the line at the carbs, stick it in a gas can, and turn the elec pump on.

That was slick and handy, but quite honestly, it was the electric pump that went south first. THe mechanical pump is still working fine in the faithful hands of Justin.
