Particle filter for underfloor fuel tank?
« on: Fri 11 Aug 08:49 2017 »
Hi all after some advice. Last trip out found the engine would shut down after running at speed for a few minutes but would be ok at trolling speeds. Found it to be a fuel problem. Emptied out my water filter today to find small black particles in the fuel. Boat has a 70lt under floor fuel tank. Is there any filters that I could use to remove these particles before the fuel hits the water filter? Only other option i can think of is to have the mechanic flush the fuel tank out.

Hi Squid, yes almost any fine filter should remove it like an EFI style filter
the only problem is that a fine filter could block up quickly, so my advice
and what I would do is clean the tank out properly and also check your
fuel lines for degradation as well.

Cheers Jason

    Taylyn's advice is spot on!  But what you've shown can also be attributed to using E10 over 91 octane and not using a fuel stabilizer.  E10 by composition has a natural occurrence to partially revert (breakdown) and form water which if left long  enough will cause settlement and sludge issues on top of which a harsher fuel which will then (or least have the potential to) present problems in older lines.  Simplest example of this is to look inside the fuel tank on your lawn mower.  That's a classic example, most will fill their tank then leave it 3/4's empty (or there abouts) and over a period there's suddenly "crud" in tank!

    Ummm, isn't that why we fit decent fuel filters and water traps for?
    Standard procedure is to change out the filters and clean the traps at regular intervals....

    One of the reasons I like using Cav filters on my petrol and diesel engines. Can see the water and other gunk as it collects.
    Most boat places will sell one with bowl and filter.
     Auto places will sell inline particle filters as well. Replace at least once a year. More often if not regular user of boat
