I have a 90 b2600i and need to replace the gas tank and the sending unit. I have searched the net and found replacement for the tank but I am having problems finding the sending unit. The units are either for non fuel injected versions or 1989 and before OR 1991 and later. NO 1990's! Can anyone give me a hand with this or has anyone been in this pickle. The truck has only 89K on it and runs great - only problem is that the tank is rusted to the sending unit and the unit is bad - pump is fine. Thanks.
