My son used this on his HellCat and it was so easy to get the lock ring off. No more punch and hammer. If you remove fuel tank lids covers frequently then this is a must.

Used tool to remove fuel pump locking ring on 2013 Mustang Convertible with V6. Tried using a punch and screw driver before ordering tool and was not able to remove ring due to need to push down on ring while removing. Was able to remove ring immediately with tool. However, removing ring from access hole was another story since ring has a larger diameter than access hole.

My fuel gauge started going haywire and a few weeks later the check engine light came on. Testing this told me that fuel sensor "A" was at fault, so I knew the one on the driver's side was bad. I bought the kit of 2 sensors and o-rings, but changed just the driver's side, which solved the fuel gauge problem after a few tanks of gas. I don't know why the delay in working properly. Other reviewers had said that sometimes the check engine light would result in engine shut-off, so I minimized…

I needed to replace the fuel pump on my 2013 Chrysler 300s. I was very happy to find this tool on Revain and for a lot less. This tool is a must for the DIY mechanic. It took me less than 5 minutes to remove the retaining ring, pull and replace the fuel pump. This tool made me look like a Pro.I definitely recommend this tool for the serious DIY home mechanic.

I bought this as a safety net when a fuel pump went out on one of our trucks, Glad I did too. You can get the lock ring off beating it around, we used the tool and it was much easier and less risk of damage. However it really shined when getting it back on! It made reinstall so much easier than trying to beat it back on.

Tried the hammer and large screw driver like I have before but the lock ring would not budge. With this it clicked right in. I used a half inch, 14inch long breaker bar with this tool and it made the job a lot easier.

Used it on my 2006 Silverado. Fit perfectly. My lock ring was so rusted it wouldn't budge until I used this. Worth every penny.

I had to apply great amount of force to turn. A long breaker bar for leverage. The tool matches the ring perfectly. That's my review!

Used it when replacing the fuel sensors. You do need a big 1/2" drive breaker bar since the locking rings are stiff. Thanks for attention.

Works perfectly. Fits any 7.25" OD metal lock rings with 7 sets of notches & clamps. I got it off OK with a hammer & punch, but it would not go on (even with an air hammer). Ordered this tool. It fit snug and went on effortlessly with a 1/2" breaker bar. PS, I pre-lubed all surfaces & o-ring with petrolium jelly.

I used this to tighten the fuel pump locking collar on my 2004 Ford Ranger. The collar came off easily with a hammer and screwdriver, but no way was it going back on the same way. I was concerned that I would damage the fuel tank by pounding on it or even drive the screwdriver through the top of the tank or worse yet slip with the screwdriver and break a nipple off the new fuel pump. I found this and it worked great. I cleaned the mating surface of the collar and fuel tank of rust and applied…

This worked perfectly to do the fuel pump on our 2012 Ford Escape 3.0. I can’t imagine trying to do this job without it. In my case the ring was stubborn coming off but went back on easily. Lubrication of the o-ring seal is probably the reason. I used a long breaker bar for removal but I think I could’ve used a cordless impact driver if I was careful. Well worth the money.

Fit perfectly to remove the DEF pump on my Ram Cummins. The universal kits just slipped off no matter how much I tightened it down. Well worth the money.

Must have product for replacing a fuel pump on my 05 F150. Most important thing is to keep your breaker bar level when using it or it will bend the retainer ring. Couldn’t have replaced the fuel pump on my 700,000+ mile f150 without it.

As much as you probably don't like spending the money on a tool that you'll use once in your life, or maybe more if you do this alot, just buy it. People and youtube videos will tell you that you can do this with a punch, or a big pair of channel lock pliers. Yeah, maybe in a perfect scenario that will work. For our work to replace the fuel pump on a 2005 Tahoe, even with this wrench which worked perfectly, I had to sit on the floor with my feet against the tank, with a 36" 1/2 breaker bar…

This tool works. The fuel pump ring was rusted on and couldn’t be removed after three hours of trying. Used the lock ring tool with a 40” breaker bar an was able to remove the ring and replace the fuel pump. Couldn’t be more satisfied with my purchase.

Worked perfectly. Way better than trying to hammer out the "hat" of the fuel pump with a hammer and flathead screwdriver.

Bought this for a Chrysler 300. Access panel is right up against the seat back, so very tight place to to get the locking ring off. This made it mildly easy and fast.

This fuel pump locking ring spanner wrench is very well made, sturdy, and nicely finished. At the price it is a great value for the vehicles it is intended to fit. Unfortunately, I apparently misread the product description and fitment guide and this particular part WILL NOT fit the locking ring on a 2003-2007 Nissan Murano. Sadly, I waited too long to get around to this particular job by which time the return window had closed. This wrench is for a larger diameter locking ring than the one on…

I used this tool on removing the def pump on a 2016 Ram3500. I had tried a punch and hammer for an hour but this tool works great and in one minute it takes the lock ring off. Very stout tool and fit perfectly.Yes, worth the money for just one job.
