What tank/filler/vent do I want on my 71 Demon 3G Hemi swap
Happy spring everyone,
I have the bottom of the Demon stripped and am ready to start working on getting the fuel tank in and lines run. This car will be getting a 6.4L crate Hemi and I'll need to build a fuel system to support that. I've pretty much decided that a Tanks Inc. fuel tank with an in-tank fuel pump is the way to go, but there are options.
I have been reading a few threads on here regarding this topic (my head is still swimming a bit) and am thinking that a 72 and up tank and a pre 71 fill tube with the vent in the top of the filler tube is probably a good choice, but will that tube fit a 71 demon?
It looks like the pre 70 A body tank has a single vent nipple located near the pump and sender unit holes, the 70 and up tank has 4 vent lines on the side. I had the factory tank and 4 vent "tube" in the trunk and the 70 - 71 only "thin" tanged gas cap. since I'm planning on replacing all of the parts, tank, filler, vent etc...and setting this up for Fuel Injection, does it make any sense to look at newer, older, or other components? I would eliminate that "tube" in the trunk If I could, but I also could keep it if it is the better system. Also what filler neck would I need if I wanted to get away from the 71 only gas cap. It looks like there are a few choices for them out there: one that matches my original, one with the with the "no lead" insert, and one with a vent nipple and hose in the top of the tube just below the gas cap.
Here is a pic of the car as it sits now and the second pic is of the trunk before I stripped the car with the filler and vent tubes.
OK, what are some recommendations and what are all of you running?
