Video of fuel Pump, sounds to me like its coming on.  Hopefully I am correct.

 

Also have video of it firing up with start fluid sprayed in it, don't think it adds much info.  

 

had similar issue last year where engine dies 75yds from driveway on way home,  coasted to my garage.

would sputter..   no fuel pressure with a gage, , but could hear pump run... did standard test of ballast resistor, etc

it was the pump, but in this instance I hired it done as I could not move it inside to access tank... was on grass and gravel, 

too old for that stuff...   had a thread on it last year sometime.

 

i mirror the post just before me, most likely in your instance with gurgling,  hose from pump to gas hose connection broken....

Yep, that was the problem.  Glad someone could pick on the pump not sounding right on the video.  Drained 5 gallons from the tank, since I know it we pretty full and then popped the fuel pump out.  Sure enough, hose was disconnected in the fuel tank on the fuel pump.  Reconnected, move the hose a bit higher than it was previously put on, hope it stays better.   Jeep fired right up, took it for a short drive and everything is back to normal.  

 

Thanks @fiatslug87 @Eagle_SX4 @Bhase @llhat and all the others who helped me diagnose the issue.  Learned a lot, hope to learn a lot more as I work on restoring, fixing, and modifying my Comanche.

if your not using submersible hose,it'll swell up and burst or it'll pop back off eventually.regular efi fuel pressure hose is not the same as submersible hose.the hose is expensive and most part stores don't carry it in stock.usually the hose that comes with a new pump is submersible.

Only had the Comanche for just over a month, not sure if the fuel pump has been replaced or not, would assume so, seems like common part that dies.  Hopefully the hose is the proper hose.  But if it comes off again I will check it.  Thanks for the heads up.

agree with statement on the type of fuel hose...    
needs to be specific for fuel injection,  'and' the submersible type inside the tank ( did not really know there was this specificity)...  got a spec rating for it or a part number?

yes one would think the complete 'kits' would have compatible hose... but..............   

 

would also advise to use the 'fuel injection clamps',  not the worm clamp as seen in the image.  

dorman markets a packaged assortment...  i think even the dastardly harbor freight has an assortment.

 

the fuel injection type clamp fully surrounds the hose with pressure and does not cut into the hose like the worm clamps

glad you found it !!!
