Fuel Pump Tank Nut Tool

thingiverse

Note: I would "ping" around the large plastic nut with a medium size hammer before trying to remove the nut. Tapping around the nut will help knock loose the nut and make it much easier to break loose!!!!!!! Also, I would place one of these on the tank nut and use small hammer to bump it around tapping on the head of the printed tool. Doing this should make on and off of the plastic tank nut easy on and off. Don't bust nut or tool or you hit too hard...... :) These are tools for removing the large plastic fuel pump ring-nuts for replacing automotive fuel pumps. These should fit most of them that have the extruding teeth around the outer edges for gripping with. There are 3 types: The "Wedge_OFF_TOOL" and the "Wedge_ON_TOOL" tools are single purpose for either taking the nut on or off. You may be able to turn one of them over or upside down and reverse the direction with a bit of patients on some applications. Others may need both. With the Wedge Tool, you will use a large screw driver or other strong steel tool to wedge in between the two risers on the side to wedge the nut around. The "Pliers_ON-OFF_Tool" can be flipped over and used to remove the nut as well as re installing the nut. I would use vise-grip pliers an clamp them on at the end of the tool. Should work well. The "ScrewDriver_ON_OFF_TOOL" will need a 1/4" diameter steel rod of sort to slide down the hole in the middle of it to give you leverage to install on or remove off the nut. The hole is 5/16" diameter and may can use a 1/4" socket drive extension as well. Anything steel that will slide down in the hole to give leverage will work. Between all of them one should do the trick. Study the photos an your application and i'm sure one or other will do the job. Print these strong using maybe minimum of 50% fill or more. The stronger the better. Should last and become your go too tool when working on fuel pumps that use the large round toothed nut as pictured. Thanks, Rick.
