2003 volkswagon polo petrol pipe popped off fuel filter

What year is you Polo? If you are in any doubt about the fuel filter change it anyway! They are usually cheap to buy.
When was the vehicle last given a full service? Oil, Air and fuel filters can cause bigger problems that you would expect. Old spark plug can do the same.
I'll need a bit more information to help. When you drive it what exactly does it do? Is it low on power? Does it struggle when you accelerate hard? Does it stall at junctions? Does it idle unevenly? Use the comment button below and I'll try to help you more.
Fuel pumps generally last a long time and only fail on very high mileage engines. The only times they fail sooner is if it have not been used properly. Running a vehicle constantly with a nearly empty fuel tank causes the pump to overheat and wear out faster.
Most 4 cylinder engines use the firing order 1,3,4,2. Number 1 cylinder is the one nearest the belts and pulleys on the end of the engine.

Replace fuel filter the get blocked. if problem persists do a fuel pump pressure test.

The fuel tank is not holding pressure or vacuum because of leak,on the filler pipe or another leak.The computer cannot hold the tank vacuum for the specified time so pops the light on.Most fuel filler pipes and vent tube for filling are one unit.

Normally fuel filters are not far from the tank, in my experience, look for a metal cylinder attached to a rubber hose coming from the tank and joining another hose going to the front. You could buy the filter for your car then get under it and know what you're looking for.

Hi. On the fuel tank under the rear of the car.

On these models, the fuel filter is part of the fuel pump assembly. Refer to Fuel Pump removal and installation.

You can buy a suction hose small enought to get intothe tank at an auto parts store. you will have to remove the fuel from the tank. All of it and then replace fuel filter.

Has the car been serviced recently?
If not I would suggest getting it done.Not sure if you have diesel or petrol, but oil can thicken causing more load on the motor and airfilters get blocked and can cause a rich fuel mixture.

If petrol you can take out the plugs to check if they are a light brown colour, if very dark or black you need to check and adjust carb/injection settings/filter.Need to know what engine it is really.

that's...thirty liters or so?...10.4 liters per hundred. I'm getting 30 UK MPG...that sounds rather low for a 1.2 . it should be getting 35-40, I believe. better get yourself a tuneup if you can afford it.

your fuel sending unit could be bad or you have a leak in the gas tank.
