troy@ Howell said I am either not getting enough fuel or getting too much.. thats why it was hunting and eventually stalling out..

i tried supply line first, nada...
threw it on the return line, leveled right out..

"bypass fuel filter and see what's going on"

volume issue... something isn't right..

I pulled these old pictures up when I built my in tank pump setup..
only other viable thing I can think of is that the pump is sucking the bottom of the tank and reducing volume, not pressure..  wondering if I have been having this issue since I landed on the tank skid oh so many years ago.. :-X

grabbing a hi volume filter and some bypass stuff today to poke around.

im still confused, was it leaking at the supply or return on the TBI?  more less or changed hose clamps should effect anything unless it was leaking?

Sorry I guess I wasn't clear...

Hose clamp restricting supply or return line to adjust fuel going in or ou of TBI.

With a fully restricted return line (hose clamp cinched down on it) I got a smooth running motor.

all these fuel issues on 2 of your jeeps and you still don't have a 20$ HF fuel pressure gage to tap in?  get some data to make some educated  next steps?

got a $15 amazon FP gauge... 8)
pressure is fine.. volume @ idle seems to be the issue..

Troy said bypass the filter and remove the clamp.. (easiest test fix)
if that doesn't cure, will have to run a volume test on the pump before dropping tank and investigating further.

I got to have some amount of trust in them.. they sell hundreds of kits to bigger idiots than me and they run successfully..
unlike the 6, I have stock location fuel lines, exhaust, a poly tank with a drop in pump already..
the only issue is the amount of fuel getting to the TB.. there has to be a restriction somewhere.

quick check when i got home..
same high flow WIX on truck as in my hand..
noticed a possible restriction in the supply hose coming from sending unit..
i think there is a groove on the top of the poly tanks where the fuel hose is suppose to curl... mine isn't in there

I wanted to get a better view of what was going on back there..
Removed the back few body bolts and lifted the body off the frame a bit with the floor jack..
jiggled the fuel hose around some and started engine.. (body lifted)
slowly releasing the restriction on the return.. had a few stall outs, wiggled fuel line some more in the back..
finally got it to idle relatively smoothly..
didn't have a barb to bypass fuel line and there isn't enough slack from the sending unit..

left for a few hours and came back later this evening, fired right up and idled steady for a few min before hunting again. ???

going to bypass the filter as instructed today and see what happens..  not looking to drop the tank without more testing, but Im going to need more than 12" of hose from sending unit... probably another previous owner mistake ;D

It's also becoming a project.
Elimination of all scotch locks and hack wiring.
Rebuilding the main gauge cluster and dash controls.

Pressure of it being in the driveway is forcing me to keep it moveable.
Everything will function or i'm burning it...
