How to adjust gas gauge to read right not reading way over filled like it does now. When 1997 chev 350 vortec truck gauge is at 1 st red mark close to empty, better not past gas station ! ! !


the fuel level sender is inside the fuel tank, part of the fuel pump assembly. did you or was the tank replaced before??they may have bent the float arm on reassembly . you can buy the sender from your parts supply store .you will have to drop the tank to do this it clips onto the side of the pump assembly. run it almost dry first as the tank is big n very heavy even 1/4 full. you can try to bend the old arm

but its very hard on the "sender" as for level indicator full to empty, think of the shape of the tank narrow at top to widest point in the middle (full to half) wide middle to narrow bottom( half to empty)

its just an overall volume thing

2002 Chev Blazer 4wd with 4.3. Cold or warm the engine cranks for several seconds before it fires. Then it runs but is flooded and takes a while to clear.


it sounds like you may have a pressure problem , not a flooding issue , this is a fuel injected motor and is probably losing fuel pressure , this could be at the gas tank , fill cap , fuel filter, to the injector rail , many places to check , I would have this checked by a pro as this is a fuel issue "BOOM"

1999 MERCURY VILLAGER BOGS WHEN GOING UP HILL WHEN ONLY 1/8TH TANK OF GAS FILLE IT UP AND THEN STILL BOGGED FOR ABOUT A MILE THEN QUIT BOGGING WHAT CAUSED THIS


when a tank is empty there is no fuel for the pump and the system runs low on fuel pressure Going up hill the fuel runs away from the pick up line and the pump sucks air
After filling it takes a while to empty the air out of the system to allow full pressure again. It is an extremely costly practice to run so low on fuel as it may lead to a pump replacement

Gasoline in a diesel tank


Hi,Did you start the vehicle after you put the gas in the tank? A drain plug is fitted underneath the tank,drain the tank of gas then fill it half way or more it may run a little sluggish at firs but the amount of diesel to gas ratio will mean it will do no harm.Hope this helps.

My kids put water in the gas tank, just a little over an 1/8th of a tank


Hi there,

Generally speaking, engines can still run with small amounts of 'water content' in the fuel, but this amount of water may cause improper combustion.

If you haven't put any additional fuel in the tank as yet, then syphon as much of the existing water/fuel mixture from the tank as you can, into a petrol container.

Then, fill the tank right up, with proper fuel - this will dilute any remaining water content.

1987 corvette with 26000 mile always garage kept from birth. Start once a week always starts inless than half a crank. But after ran down road for while and shut off takes 5-7 revolutions to fire. Almost...


Thee new fuels today go bad after around 3 weeks because of the ethonol content. Put a can of Sea Foam in the gas tank see if that helps clean it out. Best bet is to drain the tank put new fuel in it with a can of Sea Foam, then give it a good long run until the tank is empty. Re fill the tank and put the correct amount of Stabil in the with the gas, this will stop the gas from turning into sugar and it works for years.
Good luck

97 sl1 started stalling when 1/4 tank of gas now stalls at 3/4 tank replaced fuel pump and filter/regulator twice runs great when full


It seems that cap of the tank is not letting in air to replace the volume consumed by the engine. Earlier, when it used to stall when1/4 full, there must been less blockage of air but now the air inlet must be really clogged-up,so much so that after being emptied 1/4 of fuel, the negative pressure built up inside the tank is enough to negate the fuel pumps capacity & without gas it will stall the engine which is being deprived of fuel.
One way to make sure that this IS the problem, fill the tank half, do not put the cap try a drive at least for 5 miles & if the engine does not stall, then one can be sure that he cap of the gas tank has to be replaced............sodeep

Starting 1994 jeep cherokee


The Pump and Filter are Absolutely the Problem! Replace them Both. Small price to pay for Security and Cheaper than a New Jeep.

Gas tank?


It sounds odd that both cars are experiencing the same problem. This usually indicates a problem with the gas tank not venting properly.
