Cuts off and then right back on when pimping fuel

[tracker8wr]

Ok. This is alittle out the box. I leave my truck ideling while I fill it up. I fill the front tank and then the back. As the back is nearly full the truck cuts off and then right back on. As if the key was turned off then on very quickly. So I go to fill up and follow the same proceedure as before to see if it does it agin truck idling , front tank full, then rear almost full same thing truck cuts off and right back on. This was at 2 different stations and it is hard to fill my rear tank like a blocked vent tube. Any thoughts. Truck didn't stumble or miss fire before or after no issues driving.

Try filling the rear tank first, When they do that 90% of the time they loose signal from the CPS. This may not be you issue but try doing it the other way around.

Any particular reason why you need to keep the truck running when refueling?

[tracker8wr]

No i dont need to keep it running, just wounding if there is a reason anyone knows of why this would be happening. It hasn't done this in the past judged started the past couple of fill ups.

Scan for DTCs

my first question is why are you pimping fuel?
both of my tanks are a little hard to fill. I have to pull the nozzle out a bit and pull the handle only about halfway. I'm thinking maybe it momentarily blocks something off or creates a vacuum or pressurized situation or something like that. that's all just a guess cause I've never heard of anything like this. I leave mine running too, I thought it was a pretty normal thing to do?

Pimping ain't easy

I always leave my diesels running when pumping fuel too. Dont feel bad.

i leave it running while pumping, but i fill front and draw from rear, i switch to draw off the front while i fill the rear afterwards

I wondered how long it would be before the pimping started. I tried to fix it but i couldnt change the title and its hard to type on an Iphone, big fingers.

I guess i didnt specify that the truck was on the front tank for both fill-ups. It wasn't like a fuel starving or air in fuel. It was like the power was switched off and then back on. Like I said, it is strange. I was just wondering if anyone else had this issue. I searched several other forums and no mention of this. So if we can tfigure it out no big deal. Thanks for all the replies good info.

P.S. Trying to cut back on the PIMPING.
