Nor so much a Q as an A. Gas guage sender wrench Nov 13, 2014 20:05:55 GMT -5 Quote Select PostDeselect PostLink to PostMemberGive GiftBack to Top Post by w2zero on Nov 13, 2014 20:05:55 GMT -5 Just ordered one of these off ebay. It is a wrench that fits the gas guage sender retainer ring. It is a pain to remove and replace the ring with hammer and a drift and definitely worth more than the $14.50 price with shipping. www.ebay.com/itm/Mopar-Ford-Mercury-Lincoln-gas-fuel-sending-unit-tool-Wrench-/400733437258?pt=Motors_Car_Truck_Parts_Accessories&hash=item5d4d92fd4a&vxp=mtr
