Hello -

I have a 2002 Chevy Silverado 3500 cab/chassis truck, VIN 1GBJC34U22F129260. This truck has dual fuel tanks, and a 12' dump bed that was added. We need to replace the fuel filter and do some other work on this truck. First chore is to deal with the fuel filter.

The issue is that the factory manual that we have, and Chilton's, show the fuel filter being mounted on what we believe to be the passenger side of the chassis. Our filter is mounted on the DRIVER SIDE! Thus some of the instructions in the manual and Chilton's do not apply to our situation!

We need specific instructions on how to properly proceed to remove the filter from this vehicle.
The problem is that to remove the filter and the mounting bracket together, the incoming fuel line from the pump will have to be shifted backwards enough to remove that fuel line from the inlet of the filter. The filter and bracket then must be removed as one piece because there is insufficient room to extract the filter from the bracket while the bracket is mounted.

In order to be able to free the bracket totally, the two square head bolts mounting the bracket to the side frame will have to be completely removed, thus allowing the bracket to be moved sideways and backwards to separate the filter from the outgoing fuel line.

But the first step is to properly get the incoming fuel line moved backwards enough.

The following pictures are attached:

Notes:
1. These pictures were taken in Macro mode on the camera due to the closeness required, and therefore appear to show much more physical room than is really there.

2. In picture Filter Inletl, it appears as if the bracket is mounted on a horizontal surface; it is not - it is mounted on the vertical side rail. Had to put the camera at that angle to get the shot.

3. The Inlet Fuel Line pictures start at the filter end and work backwards toward the fuel pump.

4. In picture Inlet Fuel Line3, the lines turn toward the outer rail and the bottom line can be manually pressed backwards with a hand. That allows the line to be extracted from the inlet side of the filter but only about 1/2 way out. Considerably more force would be required to move the line enough to remove it completely.

5. It may be possible to also apply some backwards force on the bottom line in Inlet Fuel Line5.
Logic says it would be best to disconnect that line from the fuel pump outlet.

So ...
1. What is the overall proper procedure to extract this fuel line from the filter?
2. Can the square head bolts be removed from the bracket frame without damaging the frame?
