gas gauge needle

Would like to know Replaced instrument panel, but did not realize the position of needle on gas gauge when engine is off. Is it at E or below E and if it's below how much. 1/8 of an inch or 1/4 ?

Thanks
William

 

Just went out and checked....When shut off,the needle is well below the bottom mark and is just behind the 3 horizontal lines in "E".

Make sense?

 

I've ran mine this low

but when turned off it still goes down farther, probably about to the upright line on the 'E'. Hope this helps a little.

 

^^^^^You sir are more brave than I

 

this reminds me of that seinfeld episode lol

 

To determine where the needle should be positioned, fill up the tank to the top. Then with the key in the on position, install the needle at the full mark.

 

well, my precisely calibrated SG2 showed that I'd used 19.5 gal. at that point(right before filling it) and these trucks have a 21 gal tank so I figured I was fine. Sure enough, the pump was to the 1/10 of a gallon from what the scangauge said, just as usual.
That was the lowest i've ever gone though, plus you dont want to run too empty or else you suck up any sediments in the tank

 

If that happens we can just easily change the filter

 

yeah, but still. I don't want to have to change the filter any more than necessary.

 

I was being sarcastic about our "unserviceable" FUEL filter haha

 

The most gas I consumed in a tank was 18.7 gallons. I used my SGII as well.

 

men you two make feel feel like a pansie. I know the fuel light comes on with ~4 gallons left but once that thing turns on my mind is paranoid and constantly second guess it.

Thus the most I have pumped in is 17.8 gallons

 

I felt the same way before my SG. My SG is precise, sometimes accurate, so I sometimes test the limit. But not too much. I don't want by Taco to dehydrate.

 

Does the light come on with 4 gals left in all 2nd gens or is it different for some...I have 07 double cab...should be the same right. I have always wondered about this but the owners manual never said anything about how mnay gals were left when the light came on.Is there a possibility that two 07 double cabs could have different size tanks? probably not but thought id ask

 

Well with my truck, when I fill it up RIGHT when the light comes on (one time it came on as I was pulling into shell), it takes about 17 gallons to fill. So I assume there is 4 left in there.

 

Yeah i thougth maybe i had a 17gal tank and thats what it seems like when the pump automatically kicks off. however if i do the famous "top off" i can get about 21 in it. ive ran it low a couple times. my owners manual talks of a 17.2 or something and a 21 gal tank as well but i couldnt tell you what i have...or when the light comes on. what happened to owners manuals that told you exactly how many gals you had left? so i guess your saying i should have the 21?

 

hmm. thats interesting, but makes sense. Thanks for the lesson in fuel delivery, chris.

 

Hi guy's

So I have heard this said many times before, My question always is "does the fuel traveling through the pump or is it the fuel surrounding the pump that cools it?

For years we have used externally mounted pumps that must have been cooled by the fuel traveling through the pump.

So if it is the fuel traveling through the pump then there is no issue running your tank low.

I am not sure I buy the sediment in the bottom of the tank either, the pump is always picking up from the same spot in the tank, so how is running low going to effect this?
