Fuel Surge Protector
1675 (In-Line)

Application
Designed to work on traditional tank vent systems with standard

⁵⁄₈

" (16mm) I.D. vent hose, the In-Line Fuel Surge Protector Installs:

• Directly into the vent hose above the top of the gas tank and

10" to 12" (254mm to 305mm) below the external vent.

• At a position within 45

of vertical so that the arrow with the

word VENT points upward toward the boat’s exterior vent.

CAUTION!
Surge Protector does not prevent water intake. Install Surge
Protector below an Attwood baffled P-Trap as a splash-resistant
vent outlet.

FEATURES
Even minor fuel spills can accumulate to be a serious environmen-
tal problem. The Vent Line Surge Protector helps you protect the
environment by reducing spills through the vent line on built-in fuel
tanks.

The Surge Protector easily attaches in-line to a standard

⁵⁄₈

(16mm) vent hose from the tank. The internal ball restricts flow out
the vent line when it senses a fuel surge from boat motion or
refilling. This prevents fuel from spilling through the vent.

INSTALLATION INSTRUCTIONS

1. If this is a new vent line installation, Attwood strongly

recommends installing a baffled vent trap that will restrict
entry of splashed water

into the vent line. The Attwood

P-Trap vents are good for this purpose.

If not installing a P-Trap, a hose loop

above the vent is

necessary to trap incoming water and return it through the
vent.

2. Select an installation location that meets these criteria:

• Vent hose is

⁵⁄₈

" (16mm) internal diameter, or is adapted to

that size

• Surge Protector is installed where it won’t be stepped on

or bumped

• Center of Surge Protector is 10" to 12" (254mm to 305mm)

below exterior vent

• Arrows and word “VENT” on the Surge Protector point up

• Surge Protector is installed vertically or at an angle no

greater than 45

3. Select a point in the vent hose 10" to 12" (254mm to 305mm)

below centerline of the vent. Remove a 2

¹⁄₂

" (64mm) section

of the hose.

4. Slide hose clamps over each end of the hose. For a problem-

free installation, use worm-drive 100% stainless steel clamps.

5. Hold the Surge Protector so arrows point up and the word

“VENT” points toward the boat’s exterior vent. Slide vent line
hoses fully onto the Surge Protector. Secure hoses with
clamps, but don’t overtighten.

6. Pressure test the fuel system to make certain there are no

leaks.

CARE AND MAINTENANCE
The Surge Protector is sealed to prevent contamination and can’t
be disassembled. No normal maintenance is required.

If the ball inside doesn’t rattle when shaken, or the Surge Protector
doesn’t work as intended, replace the Surge Protector.
