I'll know exactly when I get mine back. . but you can just measure it and call them. . they are easy to talk to

 

Hehehe, I see what you did there.

 

I'm not doubting this advice, but it is the first time I've heard of it in multiple car forums I frequent. Could you give a little more technical detail as to what is "bad" about getting to reserve fuel before re-filling? Thanks!

 

There is actually truth to this. The lack of fuel in the tank causes the pump to work harder due to lack of Weight forcing the fuel into the lines. The pump ends up working extra to PULL the fuel up the lines due to Gravity.

It also allows more dirt from the bottom of the tank, (if any exists), to enter the fuel lines. (Low fuel allows the bottom of the tank to swish around more, stirring up dirt)

And lastly, (as far as I am aware), it can allow air pockets to enter the lines on hard turns, hills, etc, allowing the fuel pump to pump dry for brief moments. This causes excessive heat/wear on the pump internals.

 

Actually, the major reason that low fuel is detrimental to pump health is that the fuel acts as a coolant for the pump, as well as a lubricant. Running out of fuel causes the pump to run dry which is bad, however running excessively low can potentially allow the pump to overheat and fail as well.

 

well here goes this thread.. it was midnight and I had a long drive and didn't want to stop and fill up in the rain.. I keep a full tank, and usually on steel tanks you do it so that moisture/condensation doesn't cause rust on the empty portion of the tank.. ours are plastic

 

haha, so can I have that steering wheel wrap when your truck is rendered totaled, from low fuel cruising syndrome?

 

Nice job of bringing the thread back to the wheel wrap.

 

I did my best to stop the train before it headed off the tracks.
