I’m trying to figure out if the wc fab coolant bypass kit is all I need to take care of the coolant lines going to the egr cooler when deleting it. I already have purchased the cheap kit containing the intake block off plates and the up pipe block off plate. The kit comes with a blue hose with a bunch of different fittings for all the coolant lines but I’m not sure I’m sold on the idea of that hose it seems like it would leak. Anybody used that kit? Or have any suggestions on any other kits?

I’ve seen simpler ones that block off the water supply from the back of the engine to the cooler and just have a single hose going from the heater core to the thermostat housing. The WCFab one and others like it seem to try to mimic all the cooler connections, but there are more potential leak points that way.

Something more like this:
