The pump module MSRP is $460.99 on BRP's parts page. The retainer kit (w/ gasket) is not listed. I'd add at least a couple more hours labor at your shop's rate, for at least $150-$200 additional. If there are additional needs, such as wiring or a replacement gauge, or additional troubleshooting, that would add to the tab. The insurance adjuster, in concert with your dealer, should be doing this legwork, but I understand your need to speed up the process, and assure that they get it right.
