Dual Pre Filters for Fuel


Alan "Woody" Wood
 

Hi guys..
I have a SM'97 with a TMD22-B 
and MDKDP 6,5 KW genset and would like to change the single pre-filter for a (Racor?) dual filter.  I have no idea what the flow rate is or how to calculate it so was wondering what model of dual filter you have switched to and if you mounted the unit higher on the bulkhead to create more space below for drainage? If so, was there a problem with fuel flow from the tank or priming after changing filters?
Thanks in advance.. 
Woody

Hi woody I did same last year: rancor double filter. I am far from the boat to tell you exactly the data. Same engine, position behind the two alternators, no problem in the last 85 hours last year.
Where are you and hull number?

The Racor Duplex 500 works. Amel placed the filters low specifically to make it easy to prime/bleed with even minimum fuel in the tank without the need of a electric prime pump. Pumps that get used infrequently often get atrophy and fail prematurely.

Hi Alan,

I have the same mechanics and installed twin 7550.

Work very well.

Thanks for that Joel.. is this the model you mean..?

If mounted higher does that mean any fuel in the tank below the filter will basically be redundant without the use of an electric pump? Would it be advisable to add an extra priming pump you think?

Cheers

Glad to help Woody. That’s the one and I have seen it installed on the majority of SM 53’s and 54’s that have Racor dual filters. Some folks go larger, like the 900 and 1000 series for the much larger/able to stop more crud without blockage filter media but I think it is a bit of overkill to go larger.

The longer you own your Amel, the more inclined you will be not to change things. Amel gets it right way more often than they don’t. Leave the filters mounted low so head pressure on a near empty tank will be enough to ‘flood’ the filters and make priming/bleeding easy. Electric lift pumps that get used a time or two fail often and then you are in a bit of a pickle. Everything on a boat needs two things, maintenance AND exercise.  Try it the way Amel designed it and change it only after you have serviced the filters several times. I’m betting you won’t.

By the way although I am a salesman, I have owned three new Amel’s in my name and had several more provided to me by the Amel Shipyard, all used as demonstration boats for the North American market. I know the boats well and performed all the service on them that did not require a specialist. Part of the fun, actually.

 

Hope this is helpful and enjoy your Amel

Hi Alan,

Ooops. You are correct.  In our case, we run both the genset and the Volvo on one filter.  I change over whenever I note grunge or when changing the little element filter at the top.

Mounted on a SS plate installed on the stbd side of the engine bearer… lined up to the aft portion of the gearbox.

Works very well.

Our boat's original owner installed a dual filter long ago, a Racor 75500MAX. It gives me a lot of peace of mind. I'm pretty sure it never gave him any trouble and it hasn't given us any either. It's mounted only a bit higher than the original filter, slightly above and to the right (inboard) of it.
