Vintage OMC CRUIS-A-DAY fuel tank rebuild kit

[RICHARD A. WHITE]

Randy,
There are only 3 diaphragms used for the different pressure tanks.
Metal plunger, 4 gallon tank uses the rubberish gasket with the extra hole, that is the only gasket inside your tank.
I buy the gaskets without the hole for a $1 less and put the hole in myself
The cork gasket shown above for $5 is that gasket for your 4 and 6 gallon tank.
I see that pic of your tank, but do not see a pic of the gasket you reference.
Can you snap a pic of the part you reference 02572?

Assembly can be a pain as the spring is somewhat stiff.. There is a small aluminum disc that you must not lose…lol

Show us the part your talking about.

The metal washers on your old diaphragm transfer to the new one. Use sealant to prevent leaking at the shaft.

Maybe just get in touch with the “Gas Tank Man”.
If he can’t help, no one can.

As previously mentioned, there is no OEM all-inclusive rebuild kit from OMC.

Vintage Outboard has a compiled kit Johnson/Evinrude pressure tank repair kit #JEPT54 aluminum knob primer – VintageOutboard.com.

Amazon has an inexpensive kit, but you will need to make the ninth hole for the plunger. Amazon.com : EMIHO 2 Line Pressure Tank Rebuild Kit Compatible with Johnson Evinrude OMC, 15 Pcs : Sports & Outdoors

As you can see, the aftermarket kits vary quite a bit regarding what all is included.

Most of the time, the cap washer and the sight glass washer can be reused. The originals are made of nitrile rubber, not cork. Take note that the sight glass washer has a tapered OD. The larger OD end seats on the glass magnifier.

If you cannot reuse the screw seal washers, and prefer fiber washers, let me know and I will find some that work.

As Richard stated, be very careful to not lose the tiny round aluminum check valve disk. That tiny disk corresponds to a hole in the diaphragm and it’s very easy to install the diaphragm upside down. Yes, that was learned the hard way.
