A buddy of mines was telling me that it's bad that I always drive until the car says I need gas. He tells me the fuel pump has to work harder and driving until E can make the fuel pumps life shorter and I'll have to have it replaced?
is this true? should I always refuel when hitting near 1/4 tank?
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.
I have a 2006 F250 c/c LB and I am curious, how much fuel is left in the tank when the low fuel light comes on?
View 8 RepliesThis 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 leak in my rear fuel tank, the front tank has been blocked off and is not used, The leak is at the seam of the two part tank, once removed is there a way to seal this? or should I just replace it?
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?

View 2 RepliesI 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.....
View 5 RepliesI 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 ...
View 2 RepliesI 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?
View 2 RepliesThis 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.
View 3 RepliesI recently purchased a new prius 2015. When I first got the vehicle and filed up it would say I had approximately 600 miles to go now it says I have approximately 400 something and I actually get a little under 400. So how many miles do you get let tank? Are they mostly highway or town miles? When you fill up how many miles does your car say you have? Also I was wondering how to actually get battery meter to ever say full I can never seem to get the last bar. And when I purchased the car they told me I couldn't go any faster then 15mph in ev mode but I actually can't go any faster then 8 mpg which kind of mashes the feature useless.
View 7 RepliesI filled my 2010 Prius IV. Every day since, my indicated MPG has gone up about one MPG, with my 40 mile round trip to work.
I had been running around 46-48 MPG indicated this winter. Next day it was up over 50. Yesterday 52, today it is up to 53 mpg and I have used 1/2 tank on 256 miles, which is much better than my winter stats.
How many miles does it say you can drive after you fill up? Mine says 334 and that's what I'm getting. I want to hit 400 for a tank and can't.
View 13 RepliesI have a 2012 Prius 3 that's about 1 1/2 months old with about 1,500 miles. I remember when it had 3 miles and the dealer filled it up it showed a 600+ mile range. Since then I've had a few fill ups where I've gotten it down to about 20-40 miles left in the range and when I fill it up it's only filling up with just under 10 gallons and showing a range of about 475 miles. If I remember correctly the fuel tank is 12.9 gallons so I feel like I'm not filling up to those last two gallons. Not sure what's going on.
View 2 RepliesIn the last month, I've been getting less miles per fill up. Previously the gas light would hit 1 bar around 400 miles. Now its hitting 1 bar around 350-360 miles. But when I fill up, I only fill up about 8 gallons so I haven't lost any gas mileage. It feels as if the tank shrunk on me.
View 6 RepliesMy 4 month old Prius, while being driven by my wife, ran over a shredded 18-wheeler retread. Shortly after I noticed a very small amount of gas leaking. Took it in for 5K service, and dealer service sees the scuff marks on the undercarriage from the tire and of course doesn't cover under warranty. $1000 roughly to replace ($500 parts/ $500 labor). I saw the hole, it is literally a pinhole.
View 19 RepliesHave owned this car for 8 days and the wife is driving her normal traps, only shows having used 1/2 tank and over 240 miles, something must be wrong with this thing, must take back to dealer,
View 6 RepliesAs of recently, my 2008 Prius fuel gauge shows only 1 flashing bar unless the fuel level is more than half-full.
I just got a quote from the dealer; they said it will cost me $ 900 + to replace the whole fuel tank, as fuel gauge is not a replaceable part. Yap, the whole gas tank needs to be replaced for fuel sender!
Well, I find this hard to believe, but i guess it is possible that they have built everything together as one big replaceable unit.
BTW, if this is true then Toyota is not making environmentally friendly vehicles, when we have to throw away perfectly good gas tank and other parts within in order to replace a moving part that is most likely to fail.
