That’s what I did on my k5 before the broflow, just remember to adjust fuel pressure when you change altitude. Sea level to Moab makes it run pig rich.lol
Weekly fill-up on a 20 gallon?
I fill up my 40 gallon twice a week, sometimes eery 2 days
Yeah I commuted in my burb for a few years, ouch.
I only use it for the utility.
I also commute with my mercedes diesel half the time
Everything I can find shows 1/2" fuel line needed for 550 hp with a 46 GPH (175 LPH) pump. I would not want fitting smaller than 1/2" (-8) if I was designing the system. What you may be finding is the limitation of the stock sending unit arrangements. There is a reason for fuel cells in race cars.
This one comes with -8 AN fittings:

Now that's a freakin tank !!! Anyone tried to retro fit this to a SWB 4X4 ?
Where do you put it?
Not enough space between the rear axle and the bumper.
Haha I didn't think so Ice but it sure would be nice ! I'm trying to figure out how to run dual internal pump tanks with my EFI if even possible... That will be a separate thread...
Hey Wes, where did you source this tank? I have recently started looking and have only been able to find unbaffled tanks.
Rock auto is a great place.
Found one easily and ordered. Thanks!
I got mine at Amazon. Free shipping with prime.
Found this from Quantum Fuel Systems.

Thanks, I do not have a need for it yet, but just wanted to confirm in case something comes up down the road.
