Polishing Filter

[joe_db]

The little metal filters are light enough that IMHO I would not worry about mounting them. The more important thing is that they ARE metal, not any of the commonly available glass or plastic versions. I know it is SO tempting to use those glass filters with the replaceable elements and I have done it myself to see what was coming through, but other than troubleshooting they are way too fragile for routine use.

Step 1 - get pressure gauge. check




Step 2 Fittings on "order" from car buff friend that has extras

[sastanley]

Wow, those are fancy, but should work just fine. Be sure to mind the ID of the hose as compared to the OD of the electric blue fittings!

Yeah, my friend races, but who am I to say no

the fittings are 1/8 NPT and 1/4 hose, the "T" is 1/8 NPT.

Sooooo.. how do you build these models again?

[alcodiesel]

So according to ABYC the unsupported filter in Don's pano shot is illegal. Sheesh.

It depends on your access.
You need to figure out what will work best for you on your particular boat.
See post #10 for what worked for me.
You will probably need to use some ethanol proof pipe dope.
Careful twisting nipples into the soft aluminum carburetor to tightly. You can split the carburetor at the inlet.

Sorry.. my comment was meant as a little tongue-in-cheek but you brought a good point. With the ethanol, does anyone know if Permatex 2 is resistant? I don't see it listed, just alcohol and oil,grease resistant.

Good to know about the carb 'fragility'!

FYI ethanol is alcohol. Some cars run on methanol, but please don't drink that

[JOHN COOKSON]

I used GASOILA E-SEAL. It is made to seal ethanol laced gasoline fuel system pipe joints. It is the only product that I could find that worked with ethanol. Other products degrade over time in the presence of ethanol. Look it up on E-bay and read the reviews.

looks like Permatex PermaShield will work as well. Just have to find a local supplier...

Been a while but now that the cleaned carb is back on the engine I was able to get the fuel pressure gauge and polishing filter installed. Little more hose used than I was wanting but the space is tight and this worked.

Carb cable to adjust, new wire harness and gauges all installed, time for spring commissioning

[sastanley]

Greg, looking good..the pressure gauge instantly tells you if you have a fuel delivery problem. While 3-4 PSI seems nominal, I've seen mine run just fine as low as 1 PSI too, while motoring thru a precarious mooring field.

In that particular instance, water got in the tank from a failed o-ring in the fuel filler and the water overwhelmed the Racor so bad that it was barely passing any fuel.
