## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect fit for a Lincoln Ranger Welder
*by F***S on May 17, 2023*

We ordered the kit to replace the pump on an old Lincoln Electric Ranger 10,000-Gas Powered AC/DC CC/CV welder.(Stick,Tig,mig) Has 10,000watt generator 4:110 outlets. 1:240 outlet. Kohler engine CH233. Quick and easy to install. Fires right up and Works great! Price was reasonable and shipping was pretty fast-highly recommend this item if you are shopping for a replacement pump/kit.

### ⭐⭐⭐⭐⭐ It works as it should
*by J***. on August 8, 2023*

Had to replace the fuel pump on my Cushman Truckster. The cover bolted right on. Must use the new bolts as there is a design change in the cover. Only problem I had was that the snap ring that was included was not correct for installing the fittings. I could NOT get it expanded enough to press on the lock clips. I ended up using an IC chip puller that had just enough tab to push on the locks. Yes I know what I am doing. I have been a mechanic for over 50 years and have replaced these pumps before. Unfortunately I couldn't find the snap ring from the last pump install. Fuel pump works as it should and it starts immediately and runs fine.

### ⭐⭐⭐⭐ Overall a Good Product Except.....
*by V***6 on May 28, 2023*

I hardly ever give ratings below 5 but in this case I felt it necessary. The fuel pump arrived on time and in good shape. The 2 issues I had was 1) No instructions at all and 2) The snap ring was too large and would not have worked anyway. Found out from my local mower shop about how you clamp the side of the in and out for the gas fitting, push the fitting in and then take off the snap ring clamp which he did for me as I observed. Everything was fine then. If you order one, be sure you get instructions or ask someone how to attach the fittings and make sure you get the correct size snap ring to complete the job.
