"This is the original, not the imitator." -JK

Handy wrench built specifically to remove and install the water in fuel sensor on the Dmax LB7, LLY, LBZ, and LMM fuel filters. Also has handy slotted driver at the end of the handle for opening and closing the bleeder without damaging the screw.

Genuine GM/AC Delco pump for Dmax LB7 and LLY. Pump only no cover. Due to the tendency of the press fit to be insufficient allowing the impeller to spin we weld the hubs to the shaft on all of these pumps. These kits do include gaskets and orings, but the water pump outlet gasket is a cheap paper one so I suggest using the one listed below.

This is the proper AC Delco OE replacement pump with the composite impeller. The composite impeller does not have the issues with slip like the cast ones do therefore no need to weld anything. Includes new cover. These pumps do not include any additional seals or gaskets. See below.

This is the gasket for the outlet of the water pump where it connects to the steel pipe that leads back to the oil cooler. Fits LB7 thru LML water pumps.

This is the oring that seals the connection between the water pump and the bypass tube that connects to the thermostat crossover. Fits LB7 thru LML.

This oring seals the water pump to the timing cover/crankcase. They are typically reusable multiple times, but some prefer to replace them. Fits LB7-LML engines.

Replaces the OE WIF sensor with a simple, pretty much indestructible plug made of anodized aluminum. Accepts KD WIF wrench plus has a 3/4"-19mm hex to unscrew. Drilled and tapped with 1/8" NPT to accept a drain valve.

"The OE filter basically never collects any appreciable water so the sensor is pretty much useless. Over time the sensor can leak so why not just chuck it? Removal will not set check engine or water in fuel warning light."- JK

Replacement for that chewed up leaky WIF sensor. Consider our WIF wrench so the new one does not get chewed up!
