2
00:00:08.000 --> 00:00:10.000
John: About a week ago I brought

3
00:00:10.000 --> 00:00:12.000
our 21 foot Seabird project boat

4
00:00:12.000 --> 00:00:14.100
over here on the ?? Marina and fuel dock

5
00:00:14.100 --> 00:00:16.100
in order to put a little bit of gas

6
00:00:16.100 --> 00:00:18.100
into the craft. And I took off

7
00:00:18.100 --> 00:00:20.100
the fuel cap and I put it on the gunnel.

8
00:00:20.100 --> 00:00:22.100
And as I was messing around I kind of

9
00:00:22.100 --> 00:00:24.100
bumped it into the water and I lost it.

10
00:00:24.100 --> 00:00:26.100
Okay, not a big deal I went to the marine

11
00:00:26.100 --> 00:00:29.000
store and I tried to find a replacement cap.

12
00:00:29.000 --> 00:00:31.000
But what I've noticed is there's now

13
00:00:31.000 --> 00:00:32.600
different replacement caps out there.

14
00:00:32.600 --> 00:00:35.100
There's ones in blue packaging, like right here.

15
00:00:35.100 --> 00:00:37.100
There's also ones now in the stores that

16
00:00:37.100 --> 00:00:38.600
have green packaging.

17
00:00:38.600 --> 00:00:40.600
And obviously there is a difference

18
00:00:41.000 --> 00:00:43.000
that's going on and we

19
00:00:43.000 --> 00:00:45.200
again have Richard Cozier on the program.

20
00:00:45.200 --> 00:00:47.600
Richard is an expert in this. He's from Perko.

21
00:00:47.600 --> 00:00:49.600
And Richard thank you so much for coming by.

22
00:00:49.600 --> 00:00:51.000
Richard: John thanks for giving me a call again.

23
00:00:51.000 --> 00:00:53.000
John: My Seabird is from 1976.

24
00:00:53.000 --> 00:00:56.400
I probably redid the fuel system about eight years ago on it.

25
00:00:56.400 --> 00:00:58.400
And what type of a

26
00:00:58.400 --> 00:01:00.900
whole fuel system do I have in my particular boat?

27
00:01:00.900 --> 00:01:03.700
Richard: John basically prior to 2011

28
00:01:03.700 --> 00:01:06.600
marine fuel systems were very simple.

29
00:01:06.600 --> 00:01:08.400
They consisted of three parts.

30
00:01:08.400 --> 00:01:09.900
The fuel lever sender,

31
00:01:09.900 --> 00:01:12.900
either a vented or a sealed fuel fill

32
00:01:12.900 --> 00:01:14.900
and a vent to the atmosphere.

33
00:01:14.900 --> 00:01:16.400
John: And that's what I have on the Seabird.

34
00:01:16.400 --> 00:01:17.900
This is my configuration.

35
00:01:19.300 --> 00:01:21.700
Richard: After 2011, the EPA

36
00:01:21.700 --> 00:01:23.700
stepped in and said all boat manufacturers

37
00:01:23.700 --> 00:01:25.700
basically must now control diurnal

38
00:01:25.700 --> 00:01:27.700
emissions or hydrocarbons

39
00:01:27.700 --> 00:01:30.300
which is fuel vapor coming out of the tanks.

40
00:01:30.300 --> 00:01:32.300
So in doing so,

41
00:01:33.000 --> 00:01:35.300
the tanks got much more complex.

42
00:01:35.300 --> 00:01:37.600
They now create what's called a "ullage space"

43
00:01:37.600 --> 00:01:39.600
or an air gap inside the tank.

44
00:01:39.600 --> 00:01:42.900
They do not vent to the atmosphere. They are sealed systems.

45
00:01:42.900 --> 00:01:45.900
They now use tank vent valves,

46
00:01:45.900 --> 00:01:47.900
fill limit valves

47
00:01:47.900 --> 00:01:50.300
and inlet check valves

48
00:01:50.300 --> 00:01:53.000
that control fuel spillage back up the tank

49
00:01:53.000 --> 00:01:55.000
that's called wellback or spitback.

50
00:01:55.000 --> 00:01:57.000
John: Okay now why is though Richard,

51
00:01:57.000 --> 00:01:59.000
when you go into the marine store you look at two

52
00:01:59.000 --> 00:02:00.700
caps like these right here.

53
00:02:00.700 --> 00:02:03.700
They look identical. These are replacement caps.

54
00:02:03.700 --> 00:02:05.400
Why did they have to change the cap?

55
00:02:05.400 --> 00:02:07.600
Richard: Well basically because the older

56
00:02:07.600 --> 00:02:09.200
system cap is vented.

57
00:02:09.200 --> 00:02:11.500
If you turn it over, these two caps

58
00:02:11.500 --> 00:02:13.500
as you can see are <b><i>different</b></i>.

59
00:02:13.500 --> 00:02:16.300
This one is vented, this one is sealed.

60
00:02:17.300 --> 00:02:19.700
John: What would happen if I took a sealed cap

61
00:02:19.700 --> 00:02:21.700
and I put it on to my old system on the

62
00:02:21.700 --> 00:02:24.100
Seabird which is one that vents to the atmosphere.

63
00:02:25.100 --> 00:02:26.600
Richard: That gets very dangerous.

64
00:02:26.600 --> 00:02:28.700
That's part of why we're here discussing this.

65
00:02:28.700 --> 00:02:30.700
Because if you take a sealed cap

66
00:02:30.700 --> 00:02:32.600
and put it on to a vented system

67
00:02:32.600 --> 00:02:34.600
you're now closing off that system.

68
00:02:34.600 --> 00:02:36.200
You can over pressurize your tank.

69
00:02:36.200 --> 00:02:38.000
John: And that's dangerous?
Richard: That's dangerous.

70
00:02:38.000 --> 00:02:40.500
Richard: On the vice versa if you take a vented cap

71
00:02:40.500 --> 00:02:42.900
and put it on to a sealed fill,

72
00:02:42.900 --> 00:02:44.900
okay it's now defeating

73
00:02:44.900 --> 00:02:46.900
the EPA regulation

74
00:02:46.900 --> 00:02:50.200
and allowing emissions to come out through the fuel cap.

75
00:02:50.200 --> 00:02:52.200
John: Okay so for people at home this might be a

76
00:02:52.200 --> 00:02:54.500
little bit confusing but you're trying to make it easier on them.

77
00:02:54.500 --> 00:02:55.200
Richard: Correct.

78
00:02:55.200 --> 00:02:57.200
John: You have blue packaging for boats

79
00:02:57.200 --> 00:03:00.900
with fuel systems on a 2011 and older

80
00:03:00.900 --> 00:03:03.700
and these green ones over here these are for the newer boats.

81
00:03:03.700 --> 00:03:05.300
Let's give everyone a little tip here.

82
00:03:05.300 --> 00:03:07.000
If you do have a newer boat,

83
00:03:07.000 --> 00:03:09.600
okay go ahead and put - this is the newer cap.

84
00:03:09.600 --> 00:03:11.600
Put that on there and spin that for everybody.

85
00:03:11.600 --> 00:03:12.800
<b><i>*audible clicking*</b></i>

86
00:03:12.800 --> 00:03:16.300
John: If your boat is doing that you got a newer system right?

87
00:03:16.300 --> 00:03:18.300
Richard: Correct, but the newer systems

88
00:03:18.300 --> 00:03:20.700
the EPA says that they can make an audible

89
00:03:20.700 --> 00:03:22.500
sound as where the older systems don't.

90
00:03:22.500 --> 00:03:24.500
So now this is similar to what happens

91
00:03:24.500 --> 00:03:26.700
John: When I turn mine, mine doesn't make any noise.

92
00:03:26.700 --> 00:03:28.700
Richard: Correct. The other option is you may

93
00:03:28.700 --> 00:03:29.900
have a flip top cap

94
00:03:29.900 --> 00:03:30.600
<b><i>*audible click*</b></i>

95
00:03:30.600 --> 00:03:34.100
that makes a clicking sound to show that it's sealed and it's closed.

96
00:03:34.100 --> 00:03:36.900
John: Richard this is a pretty critical topic.

97
00:03:36.900 --> 00:03:38.900
How do viewers at home

98
00:03:38.900 --> 00:03:40.900
get more information from Perko?

99
00:03:40.900 --> 00:03:43.300
Richard: John they can go to perko.com

100
00:03:43.300 --> 00:03:45.400
and on that's we'll have all of the older

101
00:03:45.400 --> 00:03:46.800
fuel system components.

102
00:03:46.800 --> 00:03:48.800
There's also a link to our secondary

103
00:03:48.800 --> 00:03:50.800
site perkofuelsystems.com

104
00:03:50.800 --> 00:03:53.800
that has all of the EPA compliant components

105
00:03:53.800 --> 00:03:55.500
on there as well.

106
00:03:55.500 --> 00:03:57.300
John: Well I sure do appreciate you

107
00:03:57.300 --> 00:03:59.000
making us aware. Great job!

108
00:03:59.000 --> 00:04:00.000
Richard: Thanks John.
