FX Fx powerpup fill probe leak

[wickedwoods]

Hello, I recently got my fx power pup back from Cape fear airguns for a complete reseal in May... I put about 100 pellets down the barrel and now I have a slow steady leak coming from my fill probe... Reached out to Cape fear and never got an answer back..so I suppose I'm going to try to tackle this myself since apparently this gun is supposed incredibly unreliable and I can't afford to pay 200 bucks for someone to do a "complete reseal" and only change out the one bad oring (assuming that's probably the case because I shot rhis gun every day for 3 years before the main seal went and i figured if one orings bad they all probably are) so now I'm back in the the same place i was in March.
What would cause my fill probe to have a steady leak coming out of it?

Picture? When you say "fill probe" do you mean a non foster fill probe or do those have foster fittings? Not familiar with that gun. Pictures are worth a thousand words & might expedite some answers.

I appreciate that here is the picture it's coming out directly from the fitting, it's not air leaking around it... I could probably use it to fill a balloon

maybe some fine emery cloth to make sure everything is smooth and new Orings on the foster fill. only thing makes sense. Should be an easy fix. I'd call Utah airguns and ask for the Orings; how much could it possibly be. Get a tube of silicone lube too.

Just buy a whole unit from Utah and swap it out. Keep the old one for parts.

Debris. I've had some luck putting a drop of silicon oil in the hole at the top of the fill port and then top off the fill and purge the line to snap the valve shut. Just one drop of oil, but it can take a few pressure/purge cycles to work (if it is going to). Just wait for it to leak down before trying again so you don't over-pressurize the gun. The oil will lubricate the check valve and hopefully force any debris from the sealing faces. Something to try while you await your replacement part.

Well here's the culprit... Can't seem to find it in the parts pages...the impacts quick fill port looks similar

I don't see why you need to buy a foster fitting from FX directly or indirectly. I would measure the thread pitch and diameter and buy one that matches that (so you can screw it on). I would not be afraid of Amazon for this but I might also buy a "better brand" one at the same time. I have had the "cheap" one actually work better before when I've done this, however. I would be frustrated too if they showed up right after a re-ring job but it doesn't have to be something they did wrong either. It seems arbitrary why PCPs leak.
