Volvo :: MPG Falling As Fuel Tank Gets Lighter - Readings?
Aug 6, 2012
Due to my working within city, I hardly drive on highways so all my mileage readings are city readings. Recently I noticed that the mileage measurements at 3/4 full tank and 1/4 full tank were different. When I fill up the tank with 3/4 full and 1/4 of full tank left are very different. At 3/4 full, my city mpg is at 16mpg however when I fill up the tank with 1/4 of fuel left, the mileage is at 14 or less. This happens repeatedly. Could this be the sign of fuel pump dying?

Having trouble with the fuel level readings in their t-reg? When I fill mine up it shows as full but drops to 3/4 of a tank within 10 miles. Then it reads fine for about 300 or so miles and then drops to empty in about 20 or 30 miles. When I fill it back up it still has 6 or 7 gallons left. And yes, I am using 91 octane gas.

I'm new to volvo, recently I got a 240 wagon 1991 (207000km)
The old Radio is dead and I'm thinking of replacing it with a new one, My rear wiper is not working and the cigarette lighter is dead too, I hear that the rear wiper , radio, and cigarette lighter are all connected to the same circuit, is that true?
Will I have any problems installing the radio or I should just follow the radio's installation manual and it will work ?

I have a 2012 Buick Enclave that the fuel gauge fluctuate. It is not in sync with digital readings. When parking down hill the gauge goes to full. After driving a while the needle will move up a little. Even when on level ground it will fluctuate.

My boyfriend has a Volvo with 100,000+ miles, not exactly sure what year, but he recently found out the Gas Tank has a leak- ON TOP of the tank. We scratched our heads and tried to figure out how this happened. How did this happen? He does normal city driving, hasn't have an accident or bump into anything. He took it into the mechanics and they said it would be around 3000 repair/replace. How the tank got a leak on the top?

So my 7.3 started sputtering and lost power, died on the side of the road. I wasn't far from home put about 8 gallon of diesel in the tank with a couple of fuel jugs and it fired right up.
Gauge was reading 1/8 of a tank and low fuel light did not come on. (low fuel light comes on when you start) Gauge came up to about 1/2 after putting fuel in.
What happened? Gauge was always reliable and low fuel light always did work. Only work done to fuel system was had new tank straps put on a couple of months ago.

This van has had a couple of fuel pumps, no surprise there, and i need to look through my paperwork and find out how many miles the current one has on it, but it has the STRANGEST habit I've ever had on any vehicle. Starts fine, runs fine, no fuel pump noise when van is running, and when you turn it off, the fuel pump creeks on and off for several minutes.
I mean a strange creaking noise almost like a shorted electrical device or a vehicle's brakes when you park it on a hill and the breaks creak as it settles into place. I'm probably doing a lousy job of describing this but i don't know how else to describe it!
ALSO, if you lay under the van and wait til it stops creaking, you can tap the bottom of the tank and it will creak for a few more seconds. You can tap repeatedly and make it creak more. Is it about to explode? Can i trust it on a road trip?

My vehicle:
1976 F150 2wd Extended cab
390 4bbl
c6 transmission
4BBL Edlebrock Carb
Dual fuel tanks, only rear main tank connected
My problem: For the first year I owned the truck, everything ran fine and it started up really quickly even after it sat for a few days or a few weeks. I have since, for about the last year or so, had to crank it for 30-45 seconds to get it to start. This all started around the time my fuel pump went out. I replaced it with an Airtex fuel pump from Autozone. I also installed a glass in line filter before the carb in front of the distributor.
I noticed that after about 4-6 hours, the fuel had drained out of the filter and that's when I would have to crank it forever to get it going. It also seems like there is no fuel in the carb as it doesn't even try to start when it first gets cranked. I thought this was a bad pump, so I bought a new one last week and tried it again. Sure enough after about 4-6 hours, everything is empty again and it takes forever to start it. So it's not a bad pump, or so I think.
The other day I backed it into my driveway and left it, something I never do. I checked about 4 days later and there was still fuel in the filter. This makes me think that gravity is making it drain back to the tank.
Is there something that would cause this? Also I have found a one way fuel check valve online that is supposed to remedy this type of problem. Do they work for this situation? Or is there something else I should be doing to fix this? It has taken a bit of a toll on my starting system having to crank so long all the time. I have so far had to replace my starter, starter solenoid, and all the battery cables, starter cable, terminals, etc. due to excessive wear.
The valve I found is here : [URL] .....

I have a tank that's been out of my truck for a couple years. I want to clean it up real good inside before re-installing. Are there any products you can recommend that will give a deep clean on the inside to remove any gunk and some slight rust? Also, is there a product that should be used to coat the inside of the tank after it's been deep cleaned?

I am unable to get fuel delivery from tanks to engine in normal operation. I can however get pumps working with jumper wire to them. It will start with ether but not stay running on it's own. Could this be a relay or something in tfi thing ?

I have a 2004 F150 XLT 5.4 L 79,000 miles. Yesterday i was driving home turned a corner and the low fuel light came on and the fuel gauge is well below empty. I had approx 1/2 tank of fuel when it happened. I have since filled tank all the way but the gauge will not move and low fuel light stays on. Everything else is working fine! I have never run the truck low enough on fuel to make the dummy light come on.....

I have a 1986 F150 6 cyl, dual tanks, no AC, manual fuel pump. Just recently, I have been having issues with the tanks. At first it seemed like the back tank was siphoning from the front tank. Now I have fuel coming out of my front tank filler neck. When I open the back tank gas cap, there is enough pressure to spray me with gasoline. I am not familiar with the fuel delivery system of my truck ...

Lost coolant after dealer replaced a new fuel pump.
Before I start car, the level of coolant is Max and tank cap is tight. Driving back home and stop engine, the coolant level is still Max. Second day, coolant is lost and tank cap is a little loose. No more coolant loss if leaving it at home without driving. If I topped up the tank, after two days driving, coolant level is lower than MIN.
I did not find any leaks, like fuel tank and passenger's side floor.
Is it possible that tank cap causes this coolant loss?

I recently purchased a used 1999 F250 Super Duty with about 150k miles on it. The truck runs great and I have no complaints but there are a few things that need to be taken care of. It looks like there is a very small fuel leak where the filler neck ties into the rubber hose that runs into the fuel tank. There is a thin film of diesel along the side of the tank, on the leaf spring, the air bag and various other places. Nothing is dripping. I want to drop the tank and replace the hose. The Haynes manual says to depressurize the whole fuel system--is this really necessary if I don't plan on doing anything to the system aside from dropping the tank?

This is on my sig truck. I can hear the pump running, and a sound like fuel spraying around inside the tank, but not getting any up front to the carb. What is the most likely culprit for this? Can't get the bed off, or get the strap bolts loose, so I haven't been able to "eyeball" anything, yet.

I have a 1994 volvo 850 turbo wagon. While replacing the pcv breather system, I dropped a little metal clip that attaches the fuel line to the fuel rail with a t25 torx screw. I can't find the clip. What the part is called or where it can be found?
