Volvo Penta MD2020 - new fuel filter and easy bleeding of the system

The fuel filters must be changed every 2. year and this time I will like to try the cheap chinese brand Osculati wich pops up when you are searching for a alternative to the original Volvo fuel filters eg. type nr. 861477.
Osculati is a equipment chain where you can buy different stuff for your boat, a store type as Biltema or Wallmart.
Osculati then buy a lot of filters in china and then stamp on their logo and sell the filters for a affordable price.
You can find the filters at different prices and somtimes dubble the price so watch out before you click the buy botton.
Regarding the quality you get what you pay for, the Osculati filters looks like all the other filters but there is a different in the build quality there is splitting the good from the bad.
The bad thing is the filters is hard to install due to the measurements don't quite fit 100% so the best thing is to stick with the Delphi 296 for the pre-filter and go for someting else for the fine filter.
If you are on a budget the Osculati filters is ok, but as emergency filter the precision is just not good enough for a fast swap.
I have also seen the filters sold under the brand "Solas"

The filters I use in the video is :

CAV pre-filter Osculati 17.666.00 - 7,5 US Dollars
Spin-on fine-filter Osculati 17.502.02 - 16,5 US Dollars

A good alternative to the Osculati CAV filter element is WIX, Fleetguard, Hengst, Delphi, MANN, Bosch, Baldwin and also the one from Biltema.

Regarding the fuel samples the fuel will be more yellow when inside a black fuel tank or a jerrycan and it will get lighter in the color when exposed to sunlight.
The point is to spot water or diesel bug in your tank and see how it develop over time, with diesel treatment and without.

I use Liqui Moly Marine Diesel Protect in my tank, a product there is keeping the diesel bug away and also protects the diesel system against corrosion.

I also bleed the diesel fuel system on a pretty easy and new way

Thank you for this excellent video!!

This was very helpful, and in many ways.

On my D1-30 (2006 Bav 33) it is very similar but getting to that bolt on the bottom of the bowl is in a very difficult place to reach on my boat.

I accidentally broke off the bolt going at it from an awkward angle.

A mechanic showed me how he never removes the bottom bolt and just removes the top long bolt, which is easy to get to, and let’s the whole filter and bowl fall into a container. He actually just uses an old plastic one quart oil container with one side cut out which seems to be the perfect size.

Today I was changing both primary and secondary fuel filters on my Volvo MD7B and I tried your method. I worked great saving me time pumping the lever to purge the air. Thanks again.

Du er en stjerne Tino !
Jeg manglede inspiration til netop denne operation, det fik jeg her. Tak for det, jeg håber at du snart får en Bavaria igen 😊

That was excellent. On my yanmar I use a suction pump on the fine filter just before the engine. That has gone now and a Volvo 2040 is on the way so this was very helpful, thank you. Good access to your engine there. I hope my new boat is as good.

I like when you speak because I understand all your comments. 🇫🇷

[billgiles]

Thank you for the information. Your systematic way of bleeding is excellent.

Thanks for the video. I replaced my primary (engine) and secondary (Delphi) fuel filters on my Beta 20. But I started by closing tap from fuel tank then attaching a Pela oil suck-out hand vacuum pump to engine fuel pump return hose, pumped a few times to build up vacuum then opened the Delphi CAV bleed valve on top of secondary filter. This sucked out most of the fuel between second filter and fuel return pipe. When I unscrewed both filters there was hardly any spill due to both filters now drained.
With new filters now in place and all bleed screws closed, I used the hand vacuum pump once again, but this time I opened the fuel tank's supply tap and fuel system was refilled. Engine fired up fine. I did a double check on both filter's bleed valves just to make sure there was no air trapped. I don't have a manual hand pump lever on my engine's mechanical pump.

I did the change yesterday and I find that the best is to change them both together at once instead of pouring diesel in the filter, it maybe takes 10-15 times to pump and you get the diesel through the both filters. pretty simple.

[fredrikgranberg]

thanks for the instruction video. I'm about to change fuel filters on my MD2030 in my Bav36 in a couple of days :)

[conallocuinn]

Excellent presentation. I feel confident now that I too can change my filters. Thank you.

[stephanelange]

Your engine compartment is really clean.👍

[adambrickley]

Perfect thanks. Just got this engine in a new boat. Could bleed my old Perkins in 5 mins but its been a while :)

[bendix]

Thank you for the video!
When I change the fine filter at my VP2020, I fill it with fresh diesel just before I mount it. Since there is only a very small amount of air left, it will bleed out when I turn on the engine. It only takes a few more seconds for the engine to start, than regularly. And after a few seconds running, the engine is running all stable.

[lynton]

Fantastic video, thank you. Can I ask why didn't you just use your syringe to add a small amount of diesel to the top of each filter compartment rather than sucking out the air or pumping through, in the case of the fine filter? I think this would work to displace the air. Thanks😊

Thanks for the education young man, much appreciated 🎅

Hi Tino, a nice movie and help me to change the filters. I habe bought my Bavaria 32 from 2002 in die beginning of this year and it is no heating mounted. I will Install a heating and from this point can you make a short movie that i can see how is the heating mounted. Many thanks and always good luck

[nelmsgraham]

Would also, adding fuel through the top of the spin-on filter accomplish the same effect, that of removing air from the filter?

[styrbjornable]

Thanks so much for the extremely helpful videos! You mention at 25.30 m that you should make sure the engine is at top dead centre. I didn't find any mention of this in the manual when bleeding. So three questions, how important, how to check this, and how to adjust it if it is incorrect? Thanks for any guidance!

[douglundy]

see how to bleed the fuel system at 29 minutes right at the end of all the helpful lectures on tanks and maintenance.

Hi Tino, the orignal VP oil filter has a better quality then the rest. It has to do with the spring inside the filter.
