Review on MC-400 Fuel-Tool Check Valve Repair Equipment by Etai Gopala

I've spent a lot of time trying to figure out how to fix a leaking quick release valve on my 2007 FXSTD. It took several trips to the HD dealership 90 miles away to get the correct O-rings. After buying a pair of O-rings from the dealer for $0.35 each, I tried replacing the O-rings with a toothpick I had in my tool box. I removed the o-rings and removed the spring that I couldn't find. I compared the o-rings to the ones they sold me at the dealer. Not the same. So I bought this product and a check valve rebuild kit from EFI Fuel Tool (about $20). I wish I had bought the EFI Fuel Tool check valve rebuild kit first and most likely hadn't lost the spring and could have just bought the o-rings (rather than the entire rebuild kit). Anything and everything, installation was easy and the Fuel Tool website had a really good video on how to complete the installation. Today I rode the motorbike around town, no leaks. I am very happy with this purchase.
