Volvo Penta MD2020 - fuel and pre fuel filter replacement

First I drain the water separator on the pre-filter and then I replace the filter unit. After a successful refilling of the filter unit I change the fine dieselfilter and vent out the system.
To make the venting out go faster you can put on a finger to the vent hole at the fine filter while pumping, due to the pump sucks the diesel from the pre-filter and it will then create a wacuum and suck up the diesel much faster.
When the diesel almost reach the top at the vent hole you can pump out the rest of the air and then close the hole with the screw.

Hi Tino I dont know how to thank you for all the videos you have uploaded.I have a bavaria 30 cr & Volvo penta MD2020 same as yours.All engine maintenace can be done by myself by following your amazing videos, everything is brlliantly explained and everything is very clear, many thanks for your videos , I was successful on repairing the hour meter as well, thanks again!

[@patricklaine6958]

Tino, I saw your emergency fuel cut-off valve in the video. (I had the same on my Bavaria.) That valve is notorious for getting blocked by contaminants, because it is actually a valve for a gas, not a liquid. The orifice is very, very small. It blocked on my boat during a storm, and I had an engine failure (Episode 12 on my KZbin site). I explain the cause of the engine failure in Episode 13. You might want to watch that video. When I returned to France from the Azores, I replaced that emergency shut-off valve with a normal, diesel/liquid valve that has a much bigger orifice. You might want to consider doing the same. (If you Google the Bavaria shut-off valve, you will see many people have had the problem.) Very nicely explained video. Congrats.

Thanks for the info. :)

This is a very good and helpful video. I've just completed the job and wished that I'd seen before I did it. Especially like the tip about the venting in your description. It felt as though I was venting for ever! There is also mention of having a blockage in the fuel stop valve and I had exactly that problem on my Bavaria. Its apparently a common choke point so I've been researching options. I've seen an inline strainer, fitted upstream of the cock. This is intended to stop the "gunk" getting to the stop cock and looks a good solution. Anyway, thanks for posting this video it'll be helpful to lots of folks.

Also watch my new "2019" fuel filter change video where I talk about diesel bug and also the fuel cock.

[@michaelgelpi7120]

Thank you for making these videos! Your excellent videos inspire me to tackle projects that I might not otherwise attempt.

[@richardgreenwood7075]

Tino - as always a really useful video. I have the same engine in my Jeanneau SO32.2 so it's great to watch these, many thanks for spending the time to put the videos together, much appreciated !

[@seethelittlethings]

binge watching the volvo penta playlist making sure to not mess up our 2030! thanks !

[@clivepett2246]

Very helpful. Have just bought a Beneteau 331 with this system and this has helped greatly. Thankyou.

[@fredblisson]

thanks for all your details and tips....

[@MountainDoew]

Thanks a lot!

[@kduborg]

Fin video. God forklaring og beskrivelse. Tænker du kan undlade at montere pladen ved masten før det bliver forår, så kan du nemmere holde øje med eventuelle utætheder. Keep going!

[@twiper]

Tak. Jeg skal have fat på en prop så jeg kan lukke hullet af ved dæksgennemføringen, lige pt. er det bare tapet. Denne prop findes i et nyt gennemføringskit men vil se om jeg kan få proppen løs så jeg ikke skal købe hele sættet.

[@mickobrien6360]

Very clear and helpful video. A big thanks for sharing.

[@IrregularPineapples]

amazing -- exactly what I needed -- thanks a lot~

[@claude8591]

Great Video I Recently Purchased a 1983 BAVARIA 890 here in Connecticut and I'll be Replacing these Filters. You can see my Winter Project Video where I Replaced all the Old Teak & Rubber "S/V Sommerfest"

[@elizabethshaw2465]

Very clear, thank you

enjoying your videos, keep them coming

[@twiper]

Thanks. More videos is on the way :)

Hi Tino, Why are you filling the pre-filter with diesel? Not enough pumping from engine to fill pre-filter and filter? Thank you

[@twiper]

You can leave the pre-filter empty, but the problem is it will take about 1-2 hours to pump the diesel up to the engine due to the weak handpump. Also why I'm filling the fine filter at the engine, simply to make it more easy to remove all the air from the system.

[@SailMermaid]

Great video

[@twiper]

Thanks :)

[@CaptainRorke]

"Nice," Indeed

[@waltergeronius6373]

Tino, referring to the Volvo manual, there is an additional step when venting the fuel system : "3. Slacken off the injector delivery line nuts (4) and set the engine speed control to wide open throttle (WOT). Turn the engine over at WOT with the starter motor until fuel comes out of the delivery lines" I am reluctant to follow these instructions, because I can't imagine how to turn the engine with the starter motor when injector delivery line nuts are open. How did you do this? Greetings

[@twiper]

The step you are refering to is only something you do if the fuel system is completely empty or if the engine refuses to start.

[@abynormal9317]

After filters change on Volvo Penta D1-30,D2-40,D2-55,D2-75 it s enough just to pump fuel on pre filter until pump button becomes hard to push /3-5 min/.After that just start a engine.It s automaticali vent though diesel returning pipeline.You have to do step 3 only if there is no diesel between high pressure pump and injectors.

[@riccardobonfant5905]

Hi, thanks for your interestings films. I have aVP MD2010D from 2001 and I dont see how to change the thermostat. I think maybe util for everibody.

[@twiper]

Hello Riccardo. The thermostat is located the same place at the MD2010 and the MD2020, but there should not be any reason to replace it if it is in functional condition. Only if the engine is cooking and is running to hot the thermostat can be the problem. The thermostat is located between the heat exchanger alu box and the engine block, so if you must replace it you must remove a lot of parts.

[@pbt1974]

Igen en super video fra dig. Sulle nok have set den INDEN jeg skiftede for-filteret, herunder lukket for dieseltilførelsen. Kan fortælle at diesel gør dørk og cockpit meget glat:-) #readthefuckingmanual

[@hheinsius]

Tino: did you fix the hour counter that did not work ?

[@twiper]

No the hour counter has a production error, a known problem at Volvo Penta so almost every one has this problem. I have seen it work once, in my video "sailing with a KZbin fan"

[@hheinsius]

Ah, Ok. I,ve put a new, seperate, hour counter in.

[@Mechone11]

If you mount a vacuum gauge with a tee after the prefilter it will show 0 when filter changed it will slowly go up as filter plugs and change out filter when it gets between 7 and 10 inches hg. www.cruisingworld.com/how/fuel-filter-gauge/ thats what I did on my boat. I have now gone 3 years and its at 3

[@twiper]

Yes it is a smart trick, something I also have seen mounted directly on the pre-filter unit. Think it was a racor filter system.
