Default Leak at the small hose on water pump And Vacuum Pump

2016 LR4 V6 (110K miles)

Trying to find a small coolant leak, I ended up finding a bigger oil leak.

For the waterpump I found a brass fitting LR049990, or do I need to order the attaching hose as well? I found the posted waterpump thread on how to disconnect it but the updated brass fitting comes with a new push fitting, and trying to see the best way to remove it without breaking it off in there. I assume the waterpump has been replaced it looks like it has the new crossover pipes hoping I don't have to replace it for this.

Found the oil leak when I removed the skid plate trying to find the coolant leak. It looks like its the new style bake vacuum pump, would this just need to swap a gasket or full replacement? This one makes me a little nervous, mine just went out on my F150 Ecoboost and spun the toner wheel, I ended up having to replace an exhaust camshaft and ended up doing a full timing job, was not a fun project.

Also whats the most reputable place to purchase parts in the United States?







Thanks!

Make sure to replace the o-ring in the water outlet, those fail and leak. It's a bit fiddly to seat properly. The oil pump gasket's easy to replace, there's youtube video for it. Did mine over 100K miles ago and no leaks. FCPeuro provide a lifetime warranty on all parts, even wiper blades. RM european is also an excellent supplier as well as Atlantic British and of course Rock Auto but they have poor customer service and high shipping fees.

Were you able to identify a part number for that hose? The elbow snapped off when I attempted to remove from the old water pump for the new one.
