3/S Fuel Tank Repair Kit


Water finds it way up to the top of the tank, and tends to pool right there and, over time, this inevitably leads to corrosion of the various metal components. Most famous for corrosion are the studs and nuts that fasten it to the tank and also the thin-walled steel tubing that makes up the fuel feed line.

This corroded sending unit is bad enough if it's just sitting there but the minute it's disturbed (to change the fuel pump for example) watch out! Can you say SNAP! 'Cause that's a very common outcome to the studs and fuel feed line when any pressure is applied to them. 


The principal components of this repair kit are two C-shaped repair plates that are fastened underneath the top of your fuel tank and contain threaded holes (in precise locations) to accept up to six new bolts to replace any missing studs. These C-shaped repair plates are sealed to the underside of the top of the fuel tank with O-rings which provide a leak-proof seal. This repair kit can be used to replace ANY number of broken studs on top of your fuel tank, even ALL SIX of your original studs can be replaced with brand new stainless steel bolts. So no need to worry yourself about snapping those feeble, rusty studs. (We can't help but believe there exists an engineer at Mitsu with a sick sense of humour. How else can the choice of those ridiculous feeble studs be explained)?


Also included with the kit are: 


  • Four O-rings for sealing repair plates to tank. 
  • Four 5mm stainless button-head screws to attach the C-shaped repair plates to the tank.
  • Allen key for tightening above button-head screws. 
  • Six 5mm stainless hex-head bolts used to replace any broken/missing studs.
  • Two 5mm nuts for above bolts.
  • 7/32" drill bit to drill holes for any new bolts being used to replace broken/missing studs. 
  • piece of 120grit emery paper for deburring holes.


A special drill guide fixture is also available with this kit. This fixture is designed to be positioned onto the top of your tank and act as a drill guide to allow you to precisely drill all the necessary holes into the top of your tank. We consider this fixture to be absolutely essential to the repair kit and that it would be virtually impossible to drill holes in the correct places without it. The reason we don't automatically include it as part of the kit for the following reasons:


  1. You may already have the fixture (you may have multiple vehicles and got the fixture in a previous order). 
  2. You may be able to borrow the fixture from someone else.


The fact is that the fixture does not get "consumed" in the repair so it can be used over and over again. In fact, enterprising individuals may even consider trying to rent their fixture out to others. We also offer the drill guide fixture separately. (Generally, for those who ordered the repair kit without it, found out it couldn't really be done and are now ordering it. Don't worry, we understand. We must understand, that's why we offer it separately!)


NOTE: The installation of this repair kit is fairly complicated, so full installation instructions are available online, or professional installation recommended


NOTE 2: Included in the repair kit, but missing from the photo is a length of 120 grit emery paper and two 5mm nuts. Be assured, however, that they will be included in your kit.
