5.9 Magnum into a 73Duster

I remeber seeing a post with pics where a guy had the late model Charger in-tank pump assembly frenched into his stock tank. I dont recall what forum. Had to be here or moparstyle. Anyway its a alternative to a noisey external pump. My local dealerships have let me borrow service manuals with a hundred dollar security deposit. Keep in mind that vehicles with ECUs have isolated grounds all the way down to light fixtures to protect the ECU from current spikes. That may be old school today but it was a problem in the early 80s.
