Help with a leak, please!

[Episodic]

I'm leaking right at the part of the white line that goes into the water pump. I know.nothing about plumbing mostly. I know this isn't pex.

I'm not leaking at the screw cap. I'm leaking at the part that has the metal band securing that to the screw cap.

Can you tell me:
1. How do I get the ring off.
2. How do I put another on.


Can I use the existing hose or am I going to have to do both ends?


Thanks for tool advice, etc. I'm on the road and I need to do this myself as all the Rv repair places here are booked for a long time.

I'm so new, keep that in mind.

Can you also tell me what everything I'm looking at is called so I don't feel like an idiot.

It looks like the band wasn't crimped right, or maybe too tight, and cut into the hose. Go to a n auto parts/hardware store and get a small hose clamp 1/4' to 5/8' range, first. Then carefully cut off the band, check the hose for a hole and trim back if needed, check the threaded on fitting for a crack in the nipple and if all is well, install the hose clamp in its place. The original type band requires a special crimper to install.

Unscrew the water line off of the pump so you can get at it easier.. cut the band off of the hose.. remove the hose from the fitting.. REPLACE THE FITTING.. if you have enough hose cut 1/2" off (make sure the end is flat) put a compression fitting loose on the hose insert the fitting into the hose fully tighten the compression fitting... ( a hose clamp should work well) install on the water pump and test your workmanship.
