Possible fuel tank option?

[Victorofhavoc]

CFR-2014-title49-vol5-sec393-67.pdf says it doesnt need to be in front of it...unless you have different country requirements?

I believe specifically the fmvss code that drives the requirement is 301. I know it's a safety issue and has been an issue on and off for a long time. The most recent issues have been jeep not following pattern.

I totally missed out that several jeep has gas tank behind rear axle!? : r/Cartalk https://share.google/OufC3Gol72bRhZDQZ

Here's the code... It calls out fuel spillage from rear collision as the requirement and that's resolved by placing the tank under the rear seat in front of the rear axle typically. In some cases you could do other things, but without rear frame modification I don't think there's any way not to have spillage during a rear collision.

I personally would use either a walbro or a delphi (both oem manufacturers) for a separate pump...i would imagine the biggest downfall would be the extra weight of doing this. But yes legally its not allowed currently

Walbro pumps are great. I lost one three years ago with 4k track miles on it because i didn't service one of the gaskets in time, it broke and got sucked into the pump. I set it up to feed the oem pump from the offside and it worked great as an antisurge setup. I could run it to full empty and never get fuel starve. The only issue was that the float kept getting caught near the hose for it and below 50% full it wouldn't read accurately... But on track you know how much fuel you're consuming per 5mins fairly well, so easy math.

Can easily go over 300 miles on a tank. Do I wish it could go further? Yes, but 300+ also is on par with many other vehicles. I think the mindset is since it gets decent MPGs, if only it had a 17gal tank then you'd go 500 miles before fueling up, like a Camry.

the google links arent working and that cfr only quotes for spillage during an accident. do you have the specific section that discusses the axle? The one i gave only said it cant be in front of the front axle...

For your failure/issues, definitely sounds like the float should be easily correctible...the particulate matter going through the pump though, did you have the pre-filter on it?
