Hi I have a CRV 2007 Sport and would like to know why, when I have 120klm of fuel left in my tank ( according to the digital readout ), for every 5 klms or so travelled it takes off 15 klms or so from the read out. In other wors it tells me I have 120 klm of fuel left however I am only getting about 50-70 klms.
It also depents on the way you are driving.
The 120 km was for a certain driving attitude (e.g. city driving or highway driving) and depends on your mileage readout on a specific moment.
You'll also notice that sometimes you're km of fuel left will increase (without having refueled) when you enter a highway after driving in the city.(mileage increase)
If you're mileage increases, your km of fuel left will also increase with the same amount of fuel.
It's probably like the old manual fuel gauge needle where it would take longer to get from 'F' to midway than from midway to 'E'. We all know that according to the gauge the last bit of gas goes faster. I think the digital readout is doing the same thing. I don't know why though.

The fuel pump on most all modern vehicles is located within the fuel tank. Some vehicles require the removal of the tank for replacement, while others allow the pump to be replaced by removing an access panel in the interior floor. Why do you beleive the pump to be faulty?
Check for a leak in the fuel system, especially around the fuel pump and any fuel line that may have been moved during the change. Another possibility is dirt in the fuel injectors is keeping them open so they dribble in too much fuel - you may smell unburned or incompletely burned gasoline in the exhaust when the catalytic converter is cold. A problem with the ignition (bad plug or cable) will also do this, but the engine would probably run a bit rough under load in this case.
If you are getting the mileage from an instrument panel mileage indicator, have you calculated your mileage per gallon with the amount of fuel put in the tank (from the vendor pump) divided by the odometer difference from the last time you filled? Perhaps there is a problem with the fuel level sender and it's reading low.
hi it can really only be two things, first is the fuel sender on the pump inside the tank it could be stuffed or sticking causing a false reading, second it can also be a faulty fuel gauge on the dash.
The "quick disconnect" fittings for the fuel lines are usually problematic to disconnect unless you use this tip. The fittings get full of dirt over time. First, use compressed air to blow out the dirt. Then spray the connection with penetrating oil. Now insert your disconnect tool and it will come apart much easier. It's also easier to disconnect all the hoses & electrical connectors after dropping the tank down about 6 to 12 inches. Below is a video which shows how to do this job. Do yourself a favor. When you re-install the tank, apply anti seize compound to the threads of the mounting bolts. That way, if you ever have to remove it again in the future, those bolts will come out easily.
Air filter and a fuel service. I'm thinking you have changed the air filter so have the fuel system cleaned. Try bgfindashop.com
I work as a tech in a dealership and we use BG Products. They have a fuel service kit that helps. Goodluck
