Ouch
, The joys of late model vehicles. I checked here:
http://www.rockauto.com/catalog/cata...&parttype=6256
and found these variations depending on brand and model. I have found RockAuto to be one of the more reasonable places for quality parts. Your other option is salvage but who knows what you'll get and the same goes for the zone and a1 crapdone. I steer clear of them regardless of cost if it's anything I will mind replacing once a month. That "lifetime warranty" becomes pretty meaningless the third time you're laying on your back trying to wrestle that tank out especially in winter. If it were me I'd stick with Delco or GM OEM unless you can find a high perf aftermarket part like Edelbrock.
Hard to believe they can't build a pump that will last longer than that for less than a $100.00 bill in the 21st century.
Good luck with it whichever way you go.
