Fuel

Tank

Disconnect two fuel lines, two hoses, and an electrical connection

with a ground wire. There is a center fuel pump sending unit

assembly lock ring holding assembly into tank. Using a hammer

and brass punch, gently strike open edge of lock ring in a counter

clockwise direction. Keep hitting until lock ring rotates enough to

release. Again blow or brush top area clean and carefully remove

the entire assembly. Be careful on removal! Take your time!

28. FUEL PUMP ASSEMBLY

With fuel pump assembly on bench, loosen and slide up the

lower plastic clamp on top of fuel pump. Now disconnect

electrical connection. On the bottom of the fuel pump, there is a

fuel strainer sock; remove the bottom strainer sock after marking

it so you can re-assemble in the original orientation.

ALTERNATE PROCEDURE: LOWERING FUEL TANK

Suburbans (or trucks that you cannot remove the bed), require removal of the fuel tank(s). The fuel tank must be lowered from beneath the

vehicle. First drain the fuel, then disconnect the ground wire and the weather pack electrical connector. Then disconnect gas fill hose and vent

hose. Let the tank drop enough to gain access to the fuel lines, then disconnect fuel lines and remove tank from vehicle. Most tanks have two

mounting straps which must be removed.

Note: There is a kit supplied with the 3501 and 3502 that

provides you with new fuel line and clamps. Install the 3" length

of fuel hose onto the 3/8" steel tubing where the old fuel pump

junction hose was previously. Use the 3/8" hose clamp to secure

hose to steel tubing.

Note: You may want to replace the fuel sock at this time with a

new factory replacement. Use a small flat blade screwdriver to

gently pry around strainer and it will pop off. Carefully slide the

factory fuel pump out of the assembly. Install the new fuel pump

supplied in the kit into this assembly.
