ok - just didn't need to clog up the forum if not really required - thanks for the responses
So in the spirit of making things easier to maintain, over the weekend I made three strategically-placed holes in the floor to give me full access to the gas tank, including removing the sending unit to replace the fuel pump - all without having to drop the tank (and cover, and armor, and and and), and I'll make three matching bolt-on trap door panels to cover things up -
First - sending unit. There's two braces that meet up under the floor, and I cut away as much panel as I could without cutting into the braces, just to have something to start with, and lucked out because I can juuuust squeeze out the sending unit as-is :thumbsup: - and I highly recommend the sending unit ring clamp tool - like $30 on Amazon and WELL worth the $ -
Next - the OE fuel level system uses whateverthehell ohms range (still don't know for certain), so I'm using a stand-alone 8" float assembly from ISSPRO that matches my gauges, with the respective 240-33 ohms rating; drilled the hole, and I can reach inside the tank and I'll use a nice ring clamp to secure the 5 bolts from the bottom -
here's a look inside the tank - there's about...I dunno...1/4" between the bottom of the float and the bottom of the tank...so I'll have a bit 'more' after the gauge reads empty
other side -
Next - return line. My Holley Sniper EFI needs a return line, and I got this nice return line kit from EFI Systems Pro - same place I got the Sniper from - great place and great tech support -
Float and return line installed - little heat and the OE plastic return line tubing slid right over the new fitting, and used an EFI clamp to make sure it stay's put -
Next - the main vent. Wanted to be able to access the main vent and fuel full/vent tubes, so out came the deathwheel and another hole in the floor is made -
