Fuel Tool EFI Check Valve Rebuild Kit Installation Tool MC400 by Fuel Tool

I’d give it 5 stars, but the longer hook (B) wasn’t long enough for Tool (B). Not a big issue, just straighten the end that fits into the slot and it works just fine. Not sure how Fuel Tool missed this. Other than that, it is extremely easy and fixed my issue with fuel spraying everywhere from the old O rings. I keep it in my road kit just in case one of my buddies or someone on the road runs into the same problem.I emailed and received an email back from Mike at FuelTool.com. He thanked me for notifying him of the small issue I had. Trust me, If I can remove and replace the O-rings and valve spring components, anyone can. Don't get in a hurry if you don't grab the old O-rings right away. Take your time and then use the small clip they include in the kit to reach in and check if you already have it loose.

It came faster then the date that was shown so I was very happy about that, my husband really needed this part so I'd like to say great service and very reliable Thanks again!😊

Didn't work at all. Wire snapped in the check valve jamming it open and failing to remove the o ring. Now the whole tool is useless. Don't waste your money just by the check valve assembly.

I watched a youtube video before buying. It really does work, and saved me a lot of frustration, but I found out you have to be very careful to make the valve spring flush with the installation tool, before trying to instal the upper O ring, or it snags on an edge in the valve, and then gets ruined if you force it.…use plenty of lube so the O rings dont shred. Does not require any force to work. I like it. 👍🏻

Great tool and worked exactly like the video on YouTube. Replaced fuel check valve and o-rings in 5 minutes. Definitely recommend this tool . .well worth the money.
