hi there, see attached picture: i thought it was a fuel leak from the filter area but found it dripping from the large 90 degree fitting picture in the middle/top of the pic. Is this a simple tighten and or o-ring replacement repair? Not afraid to wrench on it just don't know exactly what I'm looking at and haven't had a chance to tear into it yet. Will head to the machine with wrenches in the next few days thought I would see if I could get a heads up. https://imgur.com/a/ezx1551 you can kind of see the drip forming under the large fitting. serial dmy00326
A couple of observations. 1. It appears to have been apart before judging by the paint marker "tags" someone has used to ensure they didn't miss tightening a fitting. 2. There are O-rings behind both of the joints indicated by the blue lines. The one on the hose (ORFS coupling) would likely be the prime suspect, 6V-9746 is the Part Number. 3. The large hose is not original Cat (this may potentially be a reason why it is weeping). A genuine Cat hose would have a burst protection sleeve on it like the three smaller hoses immediately to the right of it in the photo.
