Hi, looking for info on what may be causing my diesel tank to not fill to capacity. I have an '08 w/26 gal fuel tank. When it's running on fumes and even below the E, (I only let it go that low to see if it would fill better) I'm lucky to get 20.5 gal and gauge shows max full.

Thanks in advance for replies.

Its the 10 or so gallon reserve. If I go until the light comes on in my 26 gallon tank, Im lucky if I get 17 gallons in there. It's quite the annoyance when I can only get 280 miles to a tank...according to the fuel gauge.'dunno;

Normal- that is probably so you won't run out of fuel-- if you do it is a bitch to get it primed and restarted. Also if the fuel level is low and you are turning, stop and start, it can suck air and stall the engine.
