Subject:  Overfill Prevention System developments

Mike and Alan,

 

I just read the EPA Outreach Briefing from the NMMA website and thought
this would be a good time to let you know about some developments with
the OPS. I have been in contact with several of the large fuel nozzle
manufactures and all of them currently manufacture a nozzle with a spout
that would be compatible with our system. I have received samples
nozzles from a few of the manufacturers and I’m waiting for a couple
more, then I will do some tests to confirm that off the shelf nozzle
from several manufacturers will work with our system. One concern I had
was whether the nozzles would be E-85 compatible, but the engineering
people I spoke with said it was not a problem to make the necessary
changes. All were eager to be involved in developing a new market for
their product.  

 

Mike you had mentioned in a past e-mail that you wondered how my OPS
would perform in the BoatUS test. I had it tested in January by IMANNA
Laboratory and have attached their report. They ran a test on the system
to verify reliability and performance. This test was similar to the
BoatUS test only we chose an average fill rate of 15 gpm. The fill rate
is not important with our system because we don’t rely on fuel backing
up the fill hose to stop the nozzle flow. I did however want the test to
be realistic. There is a list of fuel docks and their dispensing rates
attached. These were gathered in April while trying to establish an
average dispensing rate at real fuel docks across the country.

 

Also attached are some photos of a new component that will make the OPS
adaptable to any tank with a fuel level sending unit. Fuel level senders
use a standard SAE 5 hole pattern. The adapter we have developed is
installed below the sending unit and extends to a predetermined level in
the tank. This has eliminated the need to modify anything the boat
manufacturers are currently using to install the OPS. With a standard
marine nozzle in place, any boat owner could retrofit their boat with an
OPS. By simply removing 5 screws and installing our adapter on the tank,
then 3 screws and swapping our fill fitting on the deck they would
benefit from the same overfill protection.     

 

Please keep me posted on any developments in the rule making.

Thanks,

 

Steve
