Hi open your fuel cap and see if it has compression in the tank.you will hear if there is air coming out of the tank.if so try starting it without the fuel cap,if it starts drill a small hole 2mm in the fuel cap.

Any suggestions on why once my gas tank gets to a quarter it bogs down all of the sudden and goes really slow and then will go back to normal, and then do it again as if I am running out of gas.


Try and remove filler cap, listen for the sound of air being sucked in as you remove the cap.
If there is a rush of air, see if the gauge runs normal for a while.
small chance that a negative pressure is effecting the reading.
if this resolves the issue there maybe a blocked vent or the new / recon pump may still be faulty? partially blocked fuel filter?
I had a similar issue and drilled a 0.5mm vent hole in my filler cap.
that fixed mine, best of luck.

Gas cap stuck won't come off?


Grab a pair of channel locks to get a good grip on the cap and twist counter clockwise. The back pressure created in the tank from the gas depleting can make the cap seem impossible to remove.

I want to syphon gas out of a 2005 kia rio


if the car is headed to the salvage yard anyway..if you have a drain pan thats clean or some gallon jugs that are clean, do this carefully..raise the back of the car up enough to get to the tank and have room(and help)to switch out bottles as necesary..just using a hammer and a screwdriver or b ig nail with a sharp point.. poke a hole in the tank and drain the fuel out into the bottles our drain pan..BUT..NO SMOKING...NO OPEN FLAME..NO LIGHTERS etc..this gas is very explosive and should be handled as little as posible..autozone and walmart carry an oil drainpan that sits flatways and has a drainspout on it and it holds about 6 gallons of fluid..consider using something similar before putting a hole in the tank..once the hole is made during the draining process, when needing to stop the flow to change bottles..just use your finger to plug the hole..gas liquid does not harm too much and can be removed with handsoap..the smell is a bit strong tho..it will go away after some time..just be very careful and remember this is usually NOT recommended to do..gas theives do this same thing using a portable batterypowered drill in the city.. my bosses van has a plastic fuel tank on it that hols 38 gallons of gas,, its been hit 3 times in one year...

Gasgage not going to full when i fill up.


You have to ask yourself if you really really want to fix this.

There's a float and potentiometer inside the gas tank. If the float is getting blocked from floating all the way up or the potentiometer is only going so far up, that would create this problem. The whole assembly is called the "gas tank sending unit".

The tough part is that you probably have to drop the gas tank to replace or fix these items. It's rare that cars have access holes under the back seat for this.

Fuel and temp gauge needles are under the pins after being serviced


previous owner had drilled a 1/16 size hole on the clear plastic directly in front and align with the gas needle at the area where the needle located ( usually below the empty post). use a paper clip the size of the drilled hole, bend one end slightly so it will catch the needle and drag it over the post. i did this couple times already. Do not overfill your gas tank (top-off), which will cause this needle to bounce off and go under neath the empty post. i hope this will help

WHERE IS THE FUEL PUMP LOCATED ON THE TANK. I CANT DROP THE TANK THE BOLT IS STRIPPED AND WONT COME OUT. I WILL CUT A HOLE 5" LIKE SOME OF THE EARLIER MODELS ALREADY HAVE.BEHIND THE SEAT.


Cutting a hole in it could cause you to get exhaust gas inside the cabin and I do not recommend you do this. It is easier if you just break off the bolt and drop the tank then replace the bolt. If you try to drill it out you could short out the wires on the tank or drill a hole in the gas tank and cause an explosion.Thanks for using fix-ya.

Unsolved Problem!


Have you looked at the gas or gas tank. It could be full of water. Your specific pump could be sitting up high where the gas water line settles after a period of time. Try some dry gas and run the tank out.

Original gas tank replaced because of holes. New


It sounds like the new gas tanks do not have a breather fitted to them.

As you remove gas from the tank it needs to be replaced with air if not it creates a vacuum and natures way of filling a vacuum it to compress the space it is in

Fill a plastic soda bottle with fairly hot water , give it a minute then pour the water out and quickly screw the top on , watch the effect , that is your gas tank

There is either a metal or rubber tube or even a vent in the filler cap to allow air in

You did something to alter that ?
