Jeep enthusiasts have been debating whether a TJ fuel tank fits a YJ, with some suggesting that modifications are required for a successful fit. One user on JeepForum.com shared their experience of using a TJ fuel tank in a YJ, noting that while the skid bolted up, adjustments were needed to the fill hose and the tank had to be moved to avoid contact with the left shackle. Another user on the same forum suggested that a TJ skid requires modifications to fit on a YJ and that the tailpipe may also need adjustments. Additionally, there are discussions around converting a YJ 15-gallon gas tank to a 20-gallon tank, which involves modifying the fill vent hose and fuel supply and return hoses. While some users have shared their experiences and suggestions, it is important to approach these modifications with caution and seek expert advice if necessary.

What You'll Learn
TJ skid needs modifications to fit on a YJ
The TJ fuel tank is larger than the YJ tank, with the TJ tank measuring roughly 12"H x 12"D x 32"W, while the YJ tank measures around 9"H x 19"D, with 38" between frame rails. While it is possible to fit a TJ fuel tank in a YJ, some modifications are necessary.
Firstly, spacers or similar solutions may be required to adjust the height of the skid. The YJ sending unit may not fit securely in the TJ tank hole due to the added height. Additionally, the fill tube may need modifications or a replacement. The original YJ sender did not fit the TJ tank in some instances, requiring adjustments to be made.
Furthermore, the skid may need to be pulled out and the holes redrilled to move the tank and skid to the right, as the left shackle can touch the tank seam. The fill hose may also need to be replaced, and modifications may be required for the tailpipe.
It is important to note that while some people have successfully fitted a TJ fuel tank in a YJ with modifications, others have encountered challenges in finding compatible parts. It is recommended to carefully measure and consider the specific requirements of your vehicle before attempting any modifications.

TJ fuel tank is larger than YJ tank
The fuel tank capacity of a Jeep Wrangler YJ is 20 gallons. However, the fuel tank capacity of a Jeep Wrangler TJ is 19 gallons. This means that the TJ fuel tank is larger than the YJ tank by a difference of 1 gallon.
There have been reports of people modifying their YJ tanks to fit a TJ fuel tank. One person on a Jeep forum mentioned that they had to re-drill holes and move the tank to the right to avoid touching the shackle. They also had to replace the fill hose with a copper 90 and a reducer welded to the YJ fill neck and a hydraulic hose down to the tank. Another person on the same forum mentioned that they had to use spacers to drop the skid of their YJ in order to fit a TJ tank.
It is important to note that modifying a YJ tank to fit a TJ fuel tank may not always be successful and may require additional modifications or adjustments. The YJ sending unit may not fit the TJ tank due to the added height, and the fill tube may need to be modified or replaced.
Additionally, there are different variations of the YJ and TJ fuel tanks. Some YJ tanks are plastic, while others are metal. The TJ fuel tanks also have different shapes, with some being taller and wider than others. These variations can impact the compatibility of the TJ fuel tank with the YJ model.

YJ original sender doesn't fit TJ tank
Jeep enthusiasts have reported that the YJ original sender doesn't fit the TJ tank. One user reported that they had to pull out the skid and redrill the holes to move the tank and skid to the right because their left shackle was touching the tank seam. They also had to replace the fill hose with a copper 90 and a reducer welded to the YJ fill neck and a hydraulic hose down to the tank.
Another user reported that they were able to get a TJ tank to fit in their YJ by removing the frame-mounted pump and replacing it with a piece of stainless tubing. They also had to redrill the holes to move the tank and skid to the right, and they had to replace the fill hose with a copper 90 and a hydraulic hose.
It's important to note that modifying your vehicle's fuel tank and related components can be dangerous and may not be legal for on-road use. Always consult a professional mechanic or qualified technician before making any modifications to your vehicle.
Some users have also reported that they were unable to find a YJ tank, while others have reported the opposite. This may be due to variations in model years, geographical location, or other factors.
In one instance, a user with a 1993 YJ Wrangler reported that their fuel pump sending unit would not fit in the gas tank. The issue was either due to an incorrect part or improper installation. The user was advised to compare the old and new fuel pumps to ensure that the new pump had a larger diameter at the bottom, preventing it from sitting flat on the tank to bolt properly.
In summary, while it may be possible to fit a TJ fuel tank in a YJ, modifications are likely necessary. These modifications may include changing the skid, drilling holes, and replacing hoses. It is important to carefully consider the risks and legal implications before proceeding with any modifications. Consulting a professional is always recommended.

TJ fuel pump works in a YJ
Jeep enthusiasts have been discussing the possibility of using a TJ fuel pump in a YJ model. While some sources suggest that it is possible, there are a few modifications that need to be made. The TJ fuel pump uses a higher-pressure returnless system, so you would need to use the fuel rail from the TJ, along with matching fuel lines.
One user on a Jeep forum noted that they were able to make the setup work by running the YJ fuel rail to regulate the pressure. This solution may be redundant and create more areas for potential issues, but it provides a backup in case the TJ regulator fails. Another user suggested adapting the YJ sending unit instead, as they had success using a YJ fuel rail on their setup with an external pump.
Some physical modifications are also required. One user noted that they had to pull out and redrill holes to move the tank and skid to avoid touching the tank seam with the shackle. They also had to use a copper 90 and reducer welded to the YJ fill neck, along with a hydraulic hose down to the tank.
Additionally, some adjustments to the fuel tank vent hose and fuel supply and return hoses may be necessary, as outlined in a guide for the YJ 15-to-20 gallon gas tank conversion. This conversion involves disconnecting the fuel tank vent hose and fuel supply and return hoses, as well as lowering the pump/sending unit to prevent the pickup tube from running dry.
