Floating brackets add flexibility to marine canisters
Rigid mounted equipment subjected to torsional stress while a boat is underway is vulnerable to damage. Delphi marine fuel system carbon canisters from Perko remain immune to the dangers of torque, thanks to their unique snap on floating brackets.
Instead of adapting an ordinary automotive canister, the Delphi engineering team created a design specifically for marine applications. The canisters become an integral part of the boat, yet remain flexible due to their floating bracket attachment. Comparable canisters with rigid mounts can't offer the same protection from torsional stress.
Delphi canisters from Perko feature end caps welded to an extruded body. The mounting brackets rotate on the end caps, allowing free movement without placing stress on the body of the canister. Installation is simple, requiring only four stainless steel fasteners.
The canisters contain activated carbon specially formulated for marine applications, adsorbing less moisture than regular automotive carbon. Offered in seven sizes and two hose connection choices, they meet a variety of OEM needs.
Carbon canisters come with pre-installed heat shield
Carbon canisters play an essential role in filtering hydrocarbons from the fumes vented during thermal expansion and/or refueling of marine tanks. Not content to adapt a canister designed for automotive use, Perko partnered with Delphi to create a canister from scratch, specifically designed for marine applications. Perko factory-furnishes its HS canisters with a permanent heat shield blanket, making for quick and simple engine compartment installation.
Delivered ready to mount in a boat, Delphi HS canisters come in 7 sizes ranging from 0.5-4 L. They attach with four stainless steel fasteners, just like regular Delphi marine models. The heat-shielded canisters pass ABYC-required fire tests right from the box. Boatbuilders need add no extra insulation to meet EPA certification.
All Delphi canisters from Perko contain specially formulated marine-grade activated carbon that provides less moisture adsorption than automotive carbon. The units easily snap into place with patented floating brackets that protect the canister body from stress. Perko offers two hose connection sizes, 5/8" x 5/8" and 5/8" x 5/16", on all its marine canisters.
In-Pipe Inlet Check Valve eliminates wellback and leak points
With the EPA fuel systems now mandated on new boats, builders often install an Inlet Check Valve (ICV) to prevent fuel leakage out the fill after refueling, known as "wellback." Tank-mounted ICVs are expensive to buy. Inline ICVs are expensive to install and create additional leak points. Perko's new in-pipe ICV offers an ideal solution.
This inexpensive Perko valve is installed inside the standard 1-1/2" fill pipe itself, eliminating the two potential leak points inherent with inline ICVs. It reduces costs as hose clamps aren't needed, nor is the extra installation labor associated with other ICVs.
The valve also easily retrofits into existing non-EPA fuel systems that are prone to fuel leakage or wellback problems, finally offering owners of pre-2010 boats a solution. Owners simply disconnect the fill pipe from the tank, insert the valve within it, reconnect the fill pipe and test for leaks.
Perko's new patent-pending in-pipe ICV handles flow rates up to 18 gallons/minute and can be installed on systems using either plastic or aluminum fuel tanks. The valve (P/N 0635000) retails for under $35.
Marine Canisters include new size, increased capacities
Increased fuel tank capacity ratings on Delphi marine canisters, available from Perko, now enable boatbuilders to use smaller models to meet their needs. A new 3/4 liter canister also expands Perko,s range of emission products.
Delphi canisters have been recertified to increase their capacities approximately 20%. For example, the 1/2 liter and 1 liter canisters, which were for trailerable boat tank capacities of 45 and 90 gallons respectively, are now certified for 62 and 124 gallons. The largest 4 liter Delphi canister is now certified for a trailerable boat tank capacity of 496 gallons and a non-trailerable boat tank capacity of 992 gallons.
The new 3/4 liter canister, now in production, is certified for trailerable boat tanks with capacities up to 93 gallons and for non-trailerable boat tanks up to 186 gallons. As with all Delphi marine canisters, two hose connection sizes are available: 5/8" x 5/8" and 5/8" x 5/16". It is also available with or without a heat shield. Heat shields on all Delphi canisters are factory installed and delivered ready to mount into a boat.
Specifically designed for marine applications, all Delphi canisters from Perko use specially formulated carbon and a patented floating bracket design. These snap-on brackets allow for quick, easy installation while protecting the canister from hull-induced torque.
New air and fuel separator provides internal venting
New EPA regulations regarding diurnal emissions, coupled with USCG regulations for access to tank-mounted fittings, can create compliance challenges for builders. This is especially true for users of plastic fuel tanks. Perko's new air/fuel separator offers builders a convenient, time-saving solution with this in-line venting device.
When Perko's air/fuel separator is properly located in the vent lines to the canister, there is no need to install vent valves on the tank. Manufacturers can now vent fuel tanks internally, eliminating the need for access to the far ends of longer tanks.
A small vent valve inside the air/fuel separator provides the needed airflow restriction to aid in automatic pump shutoff. This valve also provides extra protection against sloshing, has a rollover shutoff feature, and helps prevent liquid fuel from reaching the canister.
The new air/fuel separator has an overall height of less than 6", mounts using the same floating brackets used on canisters and attaches to 5/8" vent lines using standard hose clamps. A factory installed heat shield allows for engine room installation.
