Frequently Asked Questions
Why do I need an Access Plate System on my tank?
The majority of tanks are manufactured and installed with no access;
therefore no ability to be cleaned and maintained. Note: The Access
Plate System is for use on water and diesel fuel tanks - never
install it on a gasoline tank or other tanks containing highly flammable
liquids or gasses.
How many Access Plate Systems do I need for my tank?
The number of plates is influenced by the size of the tank and the
quantity of baffles. Typically one plate per baffled section of
tank. Note: Some baffles have holes large enough to clean adjacent
sections.
Is it safe to install an Access Plate System below the fluid
line on the side of the tank?
Yes, this is fine.
How large of an Access Plate System do I need?
We recommend that you install the largest plate that your install
situation will allow. The larger the hole, the easier it will be
to access and maintain the tank in the future.
Do I need to drain the tank completely before I install the
Access Plate System?
No, but be aware that the process of cutting and drilling on the
tank will allow minor bits of debris to fall into the tank. It is
best to drain the tank and clean it out completely before you finish
the installation.
What do I use to cut the hole with?
Most tanks can be cut with a saber saw and the appropriate metal
cutting blade. Have a couple of extra blades handy in case you wear
out or break one.
What keeps the backing rings from falling
in?
The outer gasket has a tight fit over the studs and prevents the
backing rings from falling into the tank - even when mounted overhead.
Should I use a gasket sealer?
No, do not use any type of third party gasket sealer. It is unnecessary
and may work against the gasket properties to seal.
How tight should I torque the assembly fasteners?
Tighten the nuts until the outer gasket is compressed and swells
slightly from the edge of the front plate. Do not over-tighten and
severely distort the gasket. Do not use gasket compound. Make sure
all surfaces are clean and dry during installation.
Why are there extra fasteners that come with the SeaBuilt Access
Plate System?
We at SeaBuilt NW know how frustrating it can be to loose something
during an improvement or maintenance project on your boat. This
is our small way of supporting you in your endeavor.
Is the Access Plate System Coast Guard approved?
Coast Guard approval is not available for our type of product. Please
see the response below from the USCG:
"The Coast Guard has different regulatory requirements for
fuel, water and holding tanks based on service of the vessel and
size. We do not "approve" fuel, water, or holding tanks
and therefore would not "approve" clean-out/inspection
ports for them.
We do not "approve" tanks. However, we have regulatory
requirements for some types of tanks on some types of vessels. Requirements
for recreational boats are in 33 CFR Part 183, for uninspected commercial
vessels you need to look at 46 CFR Subchapter C, for inspected small
passenger vessels 46 CFR Part 182. The larger commercial vessels
have more requirements which are in their applicable subchapters.
For inspected vessels the Coast Guard Officer In Charge, Marine
Inspection (OCMI) will want to verify that the tanks to be installed
are in compliance with the regulations."
