Hi guys,

I have a leak at the pressure line on the pump, the little tube that goes into the big nut at the pump is loose, I can easily move it with my hand. I’ve been reading that the o-ring might be shot but it’s a metric size. Should I just replace that o-ring or it’d be recommended to replace the pump as well? Also, does anyone knows the exact size of that o-ring?

thanks in advance!
