sounds like valve oring. On my webpage under instructions is a picture tutorial showing how to disassemble a Marauder.

All I need to now is to find the best place to purchase the O-ring and, while I have it disassembled, I may as well try some regulation mods while I'm in there :-) I am all ears if you have further suggestions! Thank you!!!
So I hadn't used my .177 SynRod in a few months and finally pulled it out, hooked up the hand pump and started pumping. As I approached the 2800 psi mark on my pump (close to 3000 psi on my gun's pressure gauge... I still don't know which is right!) I heard a loud "PFFFFFFFFFFFFFF" like air being let out of a pressurized tire. Needless to say, I blew a gasket of some sort in the airgun in what seemed like the area around the gun's pressure gauge. I am trying to resist the urge to start dismantling the gun and exploring gaskets I know nothing about and instead approach this with some level of maturity, so I am asking those who know much more than I (pretty much everyone here!) what I should do. I look forward to another opportunity to get my hands dirty and gain some knowledge at the same time, and I appreciate anyone who can prevent me from having to fix anything more than I have already broken on this gun;-) Thanks in advance for your time, knowledge, and humor!
The soapy water trick didn't work for me, so I decided to simply take the air tube out to my pool and submerge the fill end up to the pressure gauge and watch where the bubbles form. Turns out the pressure gauge relief hole on the back of the gauge was the source of my troubles. I ordered a new gauge from McMaster-Carr and I am up and running once more :-) A big thank you to all those that helped me work this out!
