I’m new to diesels,
and the preowned boat I just bought has a single Detroit Diesel equipped
with a Sea Pro fuel filter. I’ve ordered an owner’s manual (there
was none aboard) and would like some information on how to change the
element. Can you help? L.B., via e-mail
This is a pretty straightforward procedure, and you can use the accompanying
exploded diagram for reference. With the engine cool, close the fuel inlet
and outlet port valves on the fuel processor. Next, loosen the vent plug
on top of the element and remove the plug from the bottom drain valve
on the processor. Place a suitable container of at least a quart’s
capacity underneath it, open the valve, and drain the element of fuel.
Once it’s empty, close the valve and tighten the drain valve plug.
Use a suitable strap-type filter wrench to loosen the filter element,
then remove it by rotating it counterclockwise by hand. There may be fuel
left in the filter, but it will be caught by the deep well in which the
element sits and will drain back into the processor.
Remove the black plastic splash seal from the element, and retain it for
reuse. Dispose of the used element properly (consult your marina manager),
and check the new element to make sure the O-ring seal just inside the
center opening and the element seal at the base are installed. If either
of these is missing, return the element for a replacement.
Wipe the element seal contact surface on top of the processor with a clean
cloth, and lubricate the O-ring and element seals with clean engine oil.
Install the filter element onto the processor center stud by pressing
down on the element and rotating clockwise to engage the threads. Hand-tighten
only. Do not use a strap wrench or other tool to tighten the element,
as over-tightening may result in damage to the element or processor. Then
push the filter splash seal down over the fuel processor until it is firmly
Remove the vent cap at the top of the element and fill the element with
clean fuel. Replace the cap and hand-tighten. Open the fuel inlet and
outlet port valves on the fuel processor, start your engine, and check

I mixed up some epoxy, and it became very hot
and cured too quickly. What did I do wrong? D.S., via e-mail
You either mixed up too large a batch or the temperature you were
working in was too warm for the hardener. The recommended working range
is usually between 60 and 72°F, although you may want to check with
the product manufacturer. To help avoid this problem, mix smaller batches
and transfer the mixture to a container with more surface area immediately
after mixing. In addition, many epoxy manufacturers make slow hardeners
or those blended especially for warm climates.
