I decided to use a later model XJ tank for my grand waggy LS swap. The 19 gallon tank is a good fit in the spare tire location. The problem is the filter/regulator needs to be bypassed so it can deliver the required pressue. My cost was about $50 including a new universal level sending unit.
Added a return by drilling and tapping for a fitting.
Used this $35 sending unit.
Drilled and tapped the 5 holes which ARE NOT equally spaced apart
Remove the filter/regulator. Run a line so the pump discharges through the hole where the filter/regulator was. Us an external filter of your choice.
A 1/4 pipe coupling fits nicely in the hole. I secured mine with JB weld. I couldn't find a JIC/NPT elbow locally so I cobbled one together from stuff I did have.
Plumbed up the pump and slid it back into the module housing
I'm using a spin-on element
Fuel pressure is what the dr ordered and no leaks.
Fabricated some brackets to use the XJ hangers. Trimmed the original hoses and plumbed them up the the fill necks.
