Slide the supplied 11.3 stepless clamps onto the

two open legs of the Y-fitting. Connect the dis-

charge of both pumps to the previously installed

“Y” fitting using the two supplied Ø3/8" corrugated

teflon hoses. Secure the remaining hose ends

using the supplied 11.3 stepless clamps. (See

Fig. 14-h.)

Secure all hoses to the fuel pump assembly using

the supplied ties. Make sure the lid is able to

spring up and down without restriction and that

the hoses do not kink. (See Fig.

14-h.)

Use the supplied T-splice and slide connectors to

connect the black and red wires from the supplied

pump to the corresponding power and ground on

the factory pump. (See Fig. 14-h.)

Reinstall the fuel pump assembly into the fuel

tank in the reverse order of removal. Ensure that

the fuel hoses do not rub on the sharp edges of

the fuel tank. Take care not to damage the assem-

bly. INSTALLATION WILL BE TIGHT. Connect all

fuel and electrical connections. Verify that the fuel

gauge float is able to move freely. Make sure the

O-ring seal is in place and not damaged. There is

an alignment arrow on the pump assembly top

that will need to be aligned with the dot on the fuel

tank. (See Fig. 14-b.)
