Replacing in-line fuel filter on 5.7L MPI

[kbeckman]

I'd like to replace the in-line filter on my 5.7L MPI with something like the Moeller 033319.

Their website says this filter is rated at 85 PSI, but Not useable for Inboard Engines. Since I have an I/O and not an Inboard I purchased one, but the packaging says for Outboard Use Only.

Is this a Coast Guard regulation or something?

Yes that is a glass inline filter and is not legal for I/O or inboard

What is your motor serial number?

OM36xxxx

This is the one with the booster pump, that uses the 864572 in-line filter.

I'd like to replace it with a filter that I can see when it is dirty, and also if there are bubbles in the fuel line.

You could install a pre filter set up. Like a racor water separating filter and bowl with drain. I’ve one on my merc outboard. There is even a water sensor that connects and alarms to the smart craft system.
But to be honest, I have an mpi v8 too. I’ve never had an issue with fuel filtration. Just from changing the standard filter at least once a year and not leaving fuel in the tank long enough to cause any issues

Oh no not a 0 (note zero and not letter O) M36xxxx, someone might figure out who owns the motor

USCG requirements says no glass or plastic in the engine room. Same goes filters with drains like Racor, see thru or other types, must be sealed

WIX 33481 or Hlley 162-563, but personally I would remove the inline and just leave the canister, no need for 2 filters

Didn’t know that was the ruling over there AD. So do all of the likes of your average diesel cruisers, have to have their water separating primary filters, places outside the engine space ? Or enclosed in something? Where do they put them ? That’s a weird one for sure. I know that all the likes of your princess, sun seeker and the likes all have these filters installed in the engine space when built. Do they have to be changed before they are sold over there ?

Diesel is different then Gas. Diesel can have filters with drains, Gas can not

Ah. That’s a very fair point. That was my phone that posted there .

To be fair…the racor draining filter I have is inboard and fitted to an outboard boat. Thinking on it now…I can’t say I’m aware of an inboard Petrol boat that has them in the engine bay. Fair play.

I have the spin-on fuel/water filter too, which gets changed every year, but I think this in-line filter needs to be changed too.

I've see the Racor S3213 filter, and wondered if I could use in place of my Mercruiser Filter, but I wasn't sure if the threads/gaskets are the same.

I'm not worried about water, as I have never had a problem, but I like to be able to see issues as they arise.

It would be nice to be able to replace the in-line filter with a see-thru one, so I can see if it's dirty, and how the flow looks.

I have the 3213 filter on my outboard boat. Not sure it would be the same fitting. But I’d maybe say that if you want one of these so you can see any signs of anything…you might be disappointed. The bowl on the bottom will only show you if you have water collected in there, if that. Mostly you need to drain off a sample to even see that…unless your fuel is that bad that it throws obvious signs into the bottom bowl. It won’t show you the condition or clogging condition of the actual filter itself really.
Anyway. You’ll still need the in line higher pressure filter you have too. These racor filters and similar are only low pressure things and only intended to be on the LP suction side of any fuel system.

Thanks.

I'd only expect to find water in the bottom of the 3213. Do you know if the Racor 3213 and the Mercury 802893 are interchangeable?
