Hello, your tip for plugging the hose with a short 3/8" extension was very useful, thank you. My pump was jammed, i actually broke it down to see what was going on with it. All it was was the retaining screws which are torx on the inside of the pump that hold the impeller mechanism in place needed to be slackened ever so slightly. Now it runs fine and doesn't even leak which i can't believe. Maybe i should open a business servicing the pumps. Most difficult part was getting the cap back on that holds the terminals and the motor brushes. Keeping the brushes springs open to get it over the head of the stator whilst reassembling was quite a challenge. I would have never have believed that these pumps run wet with the fuel touching all areas of the motor, stator windings magnets everything. Again, can't believe it doesn't leak. Bosch deserve a medal for the design of that thing. I'll bet no end of them are replaced that don't need replacing but the user has no possibly of servicing the pump. Heavy arse shit that cover and ask the bs that goes with it. The rubber insulator just slides off . Push it from the terminals end using a few screwdrivers to prise the flaps clear. You can perhaps insert something inside the hose connection at the tank side end to push it against. Use a bit of dish washing soap around it too slide it back in again. Thanks again.
Hey , i have an 944 from 84 , and the fuel pump was not working , the Car was standing for 20 Years with 20 litres Gas in it , the fuel Tank was rusty and the oil from the gas was sticky and resinified , i was installed a new Pump , it works one week ! The Injektors were also resinified , the maschine smoked very much in the exhaust , so i was cleaned the tank and the Injektors and the new fuel pump , and now it works ! Greetings from Germany
To get the black insulation off the pump you need to slide it off by pushing it from the discharge end (with wire connections) to the inlet end. To do this put a deep socket over the inlet nipple through the hole in the black insulation. Stand the pump up on the socket so you can push the insulating sleeve down and off of the pump. At the discharge end of the pump, use a flat head screw driver to stretch the elongated opening of the insulation outwards and down around the edge of the pump body. Once the insulator is starting to move down over the socket and you have the end stretched out around the pump, keep pushing the insulator sleeve down until it comes off of the pump at the intake end (where you have supported the pump with a deep socket to protect the inlet nipple). This seems impossible at first, but with a little persistence the insulating sleeve will be off with no cutting in less than 10 minutes.
The fuel pump just pulls out. Think of the rubber bit as a cozy that slightly goes over the top of the can, unlike your short cozies;) Just peel back the top a little and pull the pump out. When I looked at it I couldn't imigine how it could come out of that small hole. The pump is much smaller then you think and pulls out fairly easily.
So just a thought. That "knock" could be lifter tick or just the injectors firing. It's hard to tell from the video but that's what it sounded like to me. That's just my 2 cents and awesome work guys. Keep it up!
Thanks Charles! We didn’t dive into it too much, but it did sound a lot like lifter tick. We’ll check it out more soon, but we really just need this engine to last one season and then the turbo stroker goes in!
I tend to agree with Charles. Porsches (plus other German cars, I've learned) are known for lifter bleed down after sitting for a much, much shorter period. My Cayman was noisy after just one winter nap. I don't hear anything I'd be concerned about, but I am listening to a video through a laptop... Keep up the good work.
Thanks for the input! We’ll wait to pass judgement until we have the fluids changed and a full tuneup. Not to mention it’s still drinking some 10 year old gas. I’m sure it will be fine, definitely not like the noises the Cayman was making!
Hey man i have an 87 944 turbo. The transfer hose from the tank to the pump collapsed and burned out my fuel pump. I'd definitely recommend replacing that little hose, oh and yeas that rubber thing does have a metal liner but it is well worth it in terms of noise in my opinion
Turn that sucker off before the timing belt breaks. I did my fuel pump and filter on my 951 about 5 years ago but I can't recall what I did with the rubber 'jacket' that was on the fuel pump, I'm getting old and forgetful.
Timing belt, water pump, balance shaft belt, rollers, fuel lines and spark plugs are all here and ready to go in! Jacket was such a weird deal, we couldn’t get it off at all. Hopefully my listening isolated does the trick!
Boost Brothers Garage haha hell yeah! Some of these cars just stink horribly! Those boots come off as well they just need a screw driver and some persuasion haha

Thanks for this. I was struggling and couldn't remember how I got that off last time. This made it super easy to remove that sleeve.
Congrats on phase 2, the comment “we don’t need brakes “ reminded me of DOC brown “ where we’re going we don’t need roads “😂🏁🤙🏽
Thanks man! Hahaha, right? If it had seats and a steering wheel you can bet we would have been out acting a fool.

Man, we tried, but the rubber wasn’t pliable at all! I wonder if ours was just shot due to age?
I followed David's suggestion and it worked a treat. Was as snug as a bug in a rug though

Thanks for the heads up!!!
Do you have a part number for the tank --> fuel pump hose?
I've installed an after market pump with out the rubber, and it is VERY loud.
Good video brah
Thanks, and thanks for commenting!
Maybe run some injector cleaner through it always helps 😎
Definitely a requirement for this one!

a basic timing/balance belt tutorial would help out :)
Consider it done!
The lifters will quiet down. Haha and old gas with water no good haha.
Michael987S it was awful lol, the smell stayed for a couple days
Boost Brothers Garage haha hell yeah! Some of these cars just stink horribly! Those boots come off as well they just need a screw driver and some persuasion haha
I should have been more aggressive!
What pump did u use?
Just a generic from Rock Auto
