How do you figure this broke your sending unit?

[/ QUOTE ] Ive never seen one of those. What does your gauge read? Maybe its stuck, try the mileage thing for awhile and maybe it'll start working again.

well when i drove into the station my guage was working and at 1/8 full and when i got in the burb to drive away aprox 20+ gallons more in the tank my needle was on E and hasnt recovered since i hope today
and how i think it broke my sending unit
i know it sounds hard 2 believe but if ya ever used 1 of these pumps before youd understand
is the pressure is so strong it bent the little metal rod that hold's the floater or pushed the floater back behind the sock or something or knocked the floater clean off its post

I honestly don't think the high speed pump broke your sender. Here's why: we used to have alot of CUCVs (still have a couple). CUCVs actually have a bigger fuel filler neck than a civilian K5/K30. The larger filler neck is necessatated by the Tank & Pump units (Fuel Pods) employed by the military. These units pump FAST! /forums/images/graemlins/eek.gif I can't quote any GPH figures off the top of my head, but the nozzle opening is about 1.5" inches. They are the same whether you're filling trucks, tanks, or aircraft. CUCVs were even equipped with the smaller (26gal) fuel tanks. I don't ever remember broken fuel sender attributed to refueling /forums/images/graemlins/thumb.gif

How empty was your tank? I once nearly ran my 6.2 dry and the next time I filled it up the gauge only went up to 1/3. Since then 1/3 has been the full mark and as the tank empties the gauge SLOWLY drops to E. I know it's not my sender because my 6.2 is in a pickup with dual tanks and the gauge reads the same for both tanks.

My theory is that by running the tank almost dry the needle got "stuck" and the gauge doesn't operate properly anymore.

So to make a long story short it might be worth checking the gauge before you start dropping fuel tanks.

well the needle is moving today almost 3/ 4 of a tank in a sharpe right hand turn so i guess when i wann check my fill level ill just swerve right a few times:-) /forums/images/graemlins/rotfl.gif

Hey, what year is your 'Burb? Just a Q, 'cause my gas 88 K5 had the fuel baffle break loose from the bottom of the tank and do 2 things (in Mexico, no less).

1- hung up my fuel level float
2- blocked the intake for the fuel pump (this makes fuses go ker-plow, oh what fun!)

This was a known TSB, maybe applies to Diesel?

The baffle is held in using similar spring clips new trucks used to hold on the brake drums from the factory. You know, the ones the original owner cut off and threw away never to replace.

My fix was simple - two thread-on nuts like you would use on the back of your door panel on each pin, problem fixed, no new tank required.

Just a thought

I doubt the pump did it. I used to fill up my Jetta at the high speed truck pumps. 15 gallon tank.
