"reserve" fuel level - ZR-1 Net Registry Forums

Regimof · 10-16-2017

So in my ongoing battle with proper fuel delivery I've come across a new and interesting question...

If the tank is 20 gallons, should my fuel gauge be reading reserve with 5 gallons left?

I think it comes on with 50 miles left. Based on the computers version of mileage.

I believe that is true. Also when you fill up you "should" hit the fuel button and I suggest the trip button to avoid a specular fuel economy surprise due to a sticking fuel float. I normally run with the range option and the trip running for just that reason. I used to have a DRM 90 L-98 as my first corvette and I ended up burning the fuel pump out due to a stuck float. Our cars are over 25 years old folks. Normal C-4 failures can and will happen. Save yourself the headache. Especially if your car stays in the garage a lot.

It's a brand new pump. Since it's been in, it turns over much longer before it starts and it tells me it's almost empty with 5 gallons left. Trying to figure out what I did wrong

A few years ago, on my way to The Gathering, I ran out of fuel w the Fuel Range showing 47 miles. Frankly I start looking for a gas station in earnest w 3 bars on Reserve.

Was the float and sock (Screen) replaced with the fuel pump ? I ask as the fuel pumps can be bought separate vs and entire unit. If you replaced the entire unit the float is sticking

Lol I get anxious at the 75 miles left mark

Whole new unit. I actually replaced it so I could see how much fuel I had left as it wouldn't read before.

It's reading now, I'm just concerned with the 2 "issues" what the deal is. Something isn't right, I feel.

Never see mine with the reserve on as I never let my tank get lower than 1/4 before I fill up. I also watch mileage and fill up every 250-300 miles.
Years back I wanted to see how the bars related to gallons in the tank. I found the first smaller bars represented more gallons each than the last bars and the reserve came on about 3-4 gallons left.

Something is wrong with that unit. Where did you get it? See if they will replace it. GC
