Recently I asked Hasbro about locating replacement QFDs. My question to them:
Will the Super Soaker Quick-Fill Device be making a return to the replacement parts page for Super Soakers? Or where could I locate one aside from second-hand places?
Their response after explaining that I did not mean the quick-fill caps used on the newer water guns:
Hi,
Thank you for your response.
The parts you are referring to are no longer manufactured.
We appreciate having the opportunity to assist you.
Given that QFDs are no longer manufacturered, I will definitely be looking into constructing homemade ones and reselling them. Tommorow I'll likely make a trip to the hobby shop to find the correct 20mm brass piping needed for a homebuilt QFD. Then, the remainder of building would be as easy as threading everything together.
