Pictures of your twin filter installation please

Here's mine. 2 Shelco SS filter housings (first 10 micron->Pump->2nd 5 micron), Carter P4070 pump. Various valves to either direct fuel back to tank or as an alternative I can bypass stock Racor 500 and push 5 micron fuel to engine in case I get a clogged filter.

In reality I never get a clogged filter or even a dirty one. I change it every fall regardless out of habit. My system is really a polishing setup with added redundancy to act as a separate fuel delivery system should I lose the Facet lift pump or get a clogged filter.

I bought the Shelcos for $14/ea on ebay brand new. The filters I buy from McMaster for $5/ea and they are enormous.

If I were to do it all over again, I would probably get smaller filter housings, mine are 10" tall. Or if I couldn't find those I'd get a pair of filter bases and run commercial screw on filters.

The one thing I don't like about mine is that the gasket is a little fussy to get just right and when you open it, you also need to prime it by pouring fuel into the housings. I could probably replumb the pump to do that but until the first filter is full it won't prime. Not a big deal really since I only change filters 1/yr and my system runs when engine is running.

Other than that I love. Always have clean fuel, Racor bowl is spotless.

I also put in a separate fuel pickup tube that goes all the way to bottom of tank corner which I found is key. Before I did this, the polisher pump was way stronger than Facet and it would starve the engine. They share a common return though.

I got a KTI Filter Boss. Works like a charm for the last four years. I have yet to put in the Walbro inline pump mentioned in this blog post, because I've yet to need it. But I have it should that change.

You will probably find solving the issue of "excessive suck" helpful as troubleshooting these installations is good to grasp.

We have Fleetguard filters on Redemption. We bought a double kit with better filtration than a Racor 500 would have done for cheaper. Purchased from Seaboard Marine (Sbmar) who sells the filter housings with gauge and sells the Fleetguard filters. The filters have two stages each. So we have filtration from 20 to 10 micron on the first filter then 10 to 5 micron on the second. No water gets passed, not even emulsified.

I'll have to snap a picture of our setup when I get to the boat.

That's a pretty nice setup. I like the spin-on filters myself since they tighten down on a good oring.

You could make a very similar setup for cheap using this dual head filter base

https://www.fleetfilter.com/filter/24093.html

and a pair of 3/4-16 threaded filters like these

Another nice filter base with NPT for a vacuum gage and built in mounting holes. Probably more common 1"-12 filter thread.

I like the squeeze bulb with clear tubing on an isolated branch idea. I'm looking to install two identical filters switchable, though...

[sailah]

Easy enough to do with a 4-6 port manifold. Could even use 1 port with a long hose to pull fuel in from jerry cans or dump all fuel in case of bad fuel. Just valves.

[captnknopf]

I have 4 Racor 500 as I have two engines. the system uses one pump, two vacuum gauges four three way valves and two four way valves as it also does the generator. It polishes using the bottom most opening in the fuel tank. There is an additional valve hooked to a hose with a length of copper tubing on it to pull fuel through the filters from a Jerry can.

[Cat36Mahalo]

Here is my install. before I attached it to the bulkhead and wired it up. Two filters each with lift pumps. Output can be routed to tank or engine. Best thing is the filter drains can have water bottle below them for draining.

You just saved me a bit of money I can spend elsewhere on my boat.

That’s exactly the sort of picture I wanted to see! Could you please tell me what the pipes around the edge are for? I.e. which of the ones that go out of shot are from tank, from jerry can, to engine 1, to engine 2, etc? Just so I fully understand.

And exactly the same question to you please. Good picture — but I can only see the fuel pump going to one filter, not the other. Where does the fuel flow on your system?

This is quite far up the stream, but we have essentially the same system of Shelcos. Here's the story and some links:

We had installed a fuel polisher in our initial refit (immediately before
our wreck); the tank was about half empty and had experienced in the range
(based on the storm duration and the period of waves) 3-5000 impacts. Ran
the polisher in the first yard, changed the filter, ran it again on the
rock-and-roll trip back to the original yard, changed the filter, and have
yet, 3000 hours later, to change a Racor.

The previous owner/builder of our boat installed a dual Racor filter system (photo attached--apologies for the low resolution). It has valving to allow for the filters to be changed individually. It is simple and does not involve a lot of fittings. I like the idea of the vacuum gauge that some here have mentioned. The way everything is situated in our boat, there is no separate lift pump to our Volvo Penta 2002. The fuel tank is immediately to the side and above the engine, so there's not a lot of line to prime and not a lot of friction to overcome.

My apologies - but I wonder if you have the PNs for both the housing and filters?

Mine are T-handle where yours are bolts, it appears, mine are 30 and 10 micron, and mine have a petcock on the bottom in place of a bung, but otherwise alike; I frequently refer folks to the polisher and dual racor solution, but don't have the PNs to tell them what to buy...

Thanks.
