Porsche 924 / 944 Fuel Gauge Repair 

Awesome! Thanks for sharing and I’m glad you got it working!

Thanks! Good luck with your project!

Thanks! Always glad to help out!

No problem, and Good luck! I drove it today and it was nice knowing how much fuel I actually have in the tank!

After 2 years of guessing the gas gauge , it's finally time to do it 👍

No problem! Thanks!

No problem! Always glad to help!

Yup! This video is for all 944's from 1982-1985.1. Good luck!

Thanks for watching!

Thanks!

Thanks!

Yes! 👍

I should have shown it in the video but I later compared this one here that I cleaned to a brand new sender out of the box and it performed exactly like the new one. Good luck!

I also made a video on the later cars fuel sender setup. I'm guessing you mean the pump at the service station? The nozzle on the service station pump uses a venturi device that knows when to stop when full. So if it isn't stopping the pump then you could have a leak in your fuel system not allowing it to stop. I hope that helps!

@@edredas you got a link for your vid on the later car for the sender setup?

No problem! I hope this helps you get it working again!

Nice video, never seen a sender taken apart before, good info..

Maybe just a washer will work? I would just use something to snug it up and it should be fine. I hope that helps!

Change the rubber fuel lines now if you still have original lines. Then send the injectors off to be cleaned and flow matched so you will know they are leaking externally. Also change the fuel pressure regulator seal and make sure there is no fuel coming out of the vacuum line on it. While these may not be your issue it’s a good place to start whenever you smell fuel since it could be a sign your car is getting ready to burn to the ground. Once those are addressed you can check the less serious issues such as charcoal canister etc. however anytime I’ve smelled fuel in the past on these cars it’s usually something bad that was luckily caught just in time.

Its a fairly straightforward system. There's a plastic line that runs from the tank to the charcoal canister behind the front fender with a 'T' in the line. The other line runs off of it to the emission control valve. Depending on the year of your car you can look up all the vacuum lines that run off of it and make sure they're connected. I also made a video on the vacuum lines that may help! Good luck!

You can try grounding the wires. The brown wire is the ground you can use. You should see the gauge go to full or the red light come on depending on the wire. If the gauge doesn't go to full, then there is an issue with the gauge itself.

@@edredas thanks!

I have been planning to do a buyers guide video that will include an early and late car, even a 924S. At the moment I either need to clean up my cars and use them in the video or borrow some some clean examples. Not sure which I'm going to do yet, but both will take some time and planning. To make it easier I might just make three separate videos instead, thanks!

Not sure since I've had to do this to every car I've ever worked on. As far as I know, carb cleaner is the only thing that works, so perhaps others have tried to clean the wires but ultimately failed to get it to work.

For me personally, I've always been intimidated to work with anything fuel related on my car. This vid made me realize, notorious fuel gauge issue fix is no big deal, as long you disconnect that battery.

Could be that someone mixed up the wires on the sender. Since the float has to go all the way down in order to turn it on, it could be that the wire is just grounded out somewhere. I hope that helps!

Check for vacuum leaks. The hoses under the intake are often forgotten and left disconnected while others are prone to deterioration.

@edradas thanks. I did notice the vacuum lines were pretty stiff. I’ll replace the rest of them.

Sometimes that happens. I've found that the round plastic piece on the bottom isn't always centered correctly. So find the side that is catching and try to remove the opposite side first. It should slip out sort of at an angle then the other side should come out. Might take a little effort but if you're careful you shouldn't really hurt it. Before re-installing it you can use some sand paper and correct the side that is catching... then just spray it off to remove any dust. I hope that helps!

Thank you. I got it with some twisting and tilting. It seemed as if the housing was a little out of shape (flared at the bottom) as opposed to the off center plastic piece. It was trouble placing it back also. Nonetheless, it works! And I have a quarter tank...who knew? I’ve learned from your other videos and I’m anticipating more. Valve job? Fuel distributor rebuild?

Hard to say, but I once worked on an early 944 with a non-functioning temp gauge. I ended up having to pull the gauge and clean the contacts. I hope that helps!

Yes, there are two different types but you can buy these new for about $115. The later model senders are around $200.

I filled up with 93. That said, NC has always had expensive gas but we have nice roads for the most part. A lot of people around here drive to SC to fill up but it really isn't feasible for me. The roads are terrible in SC, so its a trade off I guess. Also, your car will have the late fuel sender. I hope that helps!

Its a similar process but it is different. I have the sender pulled from my 1986 944 to film that episode but haven't gotten around to finishing it yet. To clean the late sender you need to remove to two hoses on top, then use an oil filter wrench to remove the ring cap. Once that's done it just comes out, but rather than using a modified screw driver you'll just need a small socket to remove the two tiny nuts. I hope that helps, and thanks!

edredas cool my speedometer doesn’t work as well I’m wondering if replacing my speed sensor will get mine to working as well?

That's usually the culprit. I don't hear about the speedometers going out too often, but I suppose it does happen. You might could try finding a cheap used one first to test with before dropping a lot of money on something that might not be the the issue. I hope that helps!
