MK1 Golf GTi Sportline FUEL pump HELP !!!!

Post

Back to the top

Need a new complete pump and sender unit

Hi all

Hope someone can help as trying to get my MK1 Sportline up and running again after nearly 10 years

I need a Fuel Pump and sender as pictured, was wondering if anyone knew the correct part numbers ( i can see 2 sets of numbers on pump itself just wanted to make sure which one I need to search up  and as you can see sender and pump is rusted  to say the least) where I can source them?

Can I buy the complete pump and sender directly from somewhere i.e Euro carparts or GSF or would I need to source individually if so part numbers and where would be helpful

Please help…

Thanks in advance!  1vw.jpg 2vw.jpg 3vw.jpg 4vw.jpg for both and

I wouldn't be surprised if your going to need a tank, filler and fuel lines as well seeing that. I'd be very careful about fitting a new pump without at least removing the tank and washing it out as you will pull all the rust into the remainder of the fuel system and damaging the metering head, WUR & injectors
Have a look on AUTODOC for the pumps, you can choose the quality of parts you want to buy, only thing delivery is a little slow

The trouble with doing nothing is that you never know when you are finished.

Thanks for the feedback and help. 

I did notice the filler neck was rusted when I topped up the fuel before finding out it didn't start due to the fuel pump … 

Thanks for the heads up , I will take a look at both the neck and the tank to avoid further damage to the vehicle,

I've had a look for the pump on the site might need to give them a call - if no luck do you know anywhere else I can try source? 

Looks like I'll have to cough up for a new tank and filler tbh 😢

No idea tbh … not sure how water could have got in ? It has been sitting for 8/9 years … 😢

The bit on the bottom is called a lift pump, the rest of it, the fuel sender are no longer available new so best to try can clean it up.

You will need to replace the bits of rubber hose as they rot over time, make sure you replace the hose so the filter at the bottom is at the same height, if it's to low it will struggle to get the fuel and it to short you may run out of fuel when there is some in the tank but it's best not to ever get that low on fuel.

There is another fuel pump underneath, drivers side just in front of the rear beam, that's the main fuel pump. :thumbs:

Thanks for that! 

I was looking at that lift pump - thanks for confirming this. I'll grab that! 

I'm worried now as the other member mentioned I might need to replace the filler neck, tank itself and fuel lines. 
Do you think this will be necessary or recommended as it only makes sense as I don't want it to ruin the engine etc running rust debris through the system? 

I'm really not sure how salvageable the sender part is as you can see it's pretty badly rusted … 

In your experience is this normal and what would you advise ?

Could you let me know about the main fuel pump, where it's located as I didn't know about this and not sure if I need to replace this also, could you send a link please? 

Thanks again for your help! 🙏

This is an overview of the components in the fuel system, and in fact if you look around the site all the parts of the car, you'll need to look for your specific model
Have a good look under the drivers side sill, you will see the fuel pipes running along the floor of the car, follow them back and you will find the main fuel,pump, in a foam sleeve inside a metal cage, you will also find the fuel accumulator there, it will look rusty but make sure they aren't leaking.
If you are competent you could disconnect the supply hose from the tank to the fuel pump and drain out the tank, please read up on the dangers of working with petrol, and have a suitable container & method of disposal. You can make an inspection inside the tank from the level sender you already have removed, ( try soaking this in white vinegar for a day or two) Then disconnect the fuel supply line from the fuel filter and see if the main pump is working, this will also help to reduce any junk being pumped into the metering head, try to see what the fuel is like, dirty rusty etc
You should hear this pump prime up when the ignition is switched on. I'd be surprised if it's survived looking at the sender and lift pump! There is a relay to power this so if it doesn't prime up there are a few more checks before condemning it
Make a good assessment of the condition of the parts before trying to start it, decide if it's worth the risk of pulling junk into the metering head & injectors if the fuel tank and lines are ropey and consider timing belt water pump etc after being idle for so long. I'd also remove the central lead from the distributor and crank the engine for some short bursts to get oil around all the internals and get the oil light to go out during cranking before attempting to get it to run

Hi Jake,

Thanks for all your help.

I'm currently soaking the sender in white vinegar - seems to be doing the job - hopefully works once fitted to mew fuel lift.

Thanks again  AD50B8DB-E700-4932-A07B-0B315A71987B.jpeg

I'm sure that new senders are available, I was messing with mine earlier this year and came across a supplier…. I just can't remember where …..

The fuel sender in the link above is for tin top Gti as they have a smaller petrol tank and the fuel comes out from the bottom of the tank not the top like yours so it won't fit or work.

As said look inside the fuel tank with a torch via the hole from the sender unit to see what it's like inside. The fuel left inside the tank has probably gone off and need draining out.

To check the fuel filler neck remove the filler cap and shine a torch down it, if you see rusty holes replace it. Have a look under the wheel arch and check the condition of the filler neck.
Cabriolet fuel filler necks are different from tin tops and for some reason 3 times the cost.

The fuel pump may not prime when you switch the ignition on, mine doesn't as I've a No. 62 fuel pump relay  and they don't prime as you don't really need to prime the fuel system to start the car.

New fuel filter is a must, it's in the engine bay near the metering head.

Dragging through old dirt petrol thought the injection system is never going to end well as the k-jet is sensitive and parts are getting expensive now so worth making sure it's a clean as it can be.

One last thing… make sure you are using Super unleaded as they prefer it and now with extra ethanol in normal unleaded (E10) it's worth avoiding.

Have a google as lots of info online about Bosch k-jet, or ask on here.
