If it still pumps up but then leaks air it is probably a tubing leak. If you want to fix this you are probably going to have to open it up and reattach the tubing from where it has come off.

Any Blaster mod or homemade that I post I can commission. Send me a PM on NerfHaven or BritNerf or email me by sam@lusher.org.uk

There is no tubing in a Sm750...

Anyways you might want to try flushing out your tank with water in case any debris got onto the front sealing surface. Other than that do a water-test and seal any leaks with a healthy helping of Goop.

I believe I saw the same auction for it, the seller said the barrel didn't have a good seal, so I'd say redo the barrel with 6" PETG after fixing the leak. Other than that, be sure to do the water-submersion leak test and goop any possible leaks on the internals.

I saw that same auction (it was by Blue I think) and I'm pretty sure he said the rubber seal at the front of the tank didn't fully seal. I'm not sure though.

Hello, sounds like the Sm750 I sold Sale. I don't recall any leaking issues, but the seal in the pump is messed up as I noted. If I had to guess, I would say that it was overpumped or that the check valve is shot seeing as it worked for two days after it was received. I didn't mod the blaster, so I can't tell you what it looks like inside. However, because the internals are basically all one piece, you can easily leak test the internals by just opening the blaster and putting it under water after pressurizing it. I suggest that you take photos of any bubbles you see then cover them in super glue or some other sealant. If the check valve is shot it will have bubbles coming out of the pump tube, this is a much harder problem to fix.


And just a disclaimer since I have not gotten feedback yet, I sold the blaster AS IS and I am not responsible for any damage done after the post office delivers the item or if in your attempts to repair the blaster you end up damaging it further. Please pm me here or on ebay if you have any questions, I appreciate your business. Thanks!

Whoops, yeah that was probably it. Anyway, I'm not sure, but I though 6" PETG barrels were better for SM750s?
