Fuel filter not GF-481 oer wcc web site??

[JimAerbus,W22,2003]

I am getting ready to change the fuel filter on my 03 W22 chassis and looked up the number on the Workhorse web site, they say it is a GF-481 which is a very common filter for Corvette and several other GM cars. 18dollars +/- at Napa. Is this in fact not the correct filter. Saw on another post where people where having a hard time finding it and paying crazy money..Is workhorse carrying a wrong number. I want to get the filter BEFORE I take the old one off. regards, Jim PS: I understand that newer chassis have different filters, but I'm talking about an 03.

I have Dec 03 chassis and it HAD the new style WCC only filter. Crawl under the rig and look to see if you have a 1 piece filter or a 2 piece filter. The 2 piece takes the GF-481 style.

Dale, I'm not sure what you mean by a one or two piece filter. The 04 and up chassis has a filter with 3 lines going to it. The 03 and earlier have a filter with 2 lines. Like you say, just look at it and you can tell.

04 > FILTER - 1 PIECE



03 < FILTER - 2 PIECE


2 PIECE INSTALLED


Oon Edit:

Note the pre-04 filters do not have the "T"

[al koffman]

What is the part number and where would one buy the two piece filter?

[kennersonf]

I have a 2003 W22 and my fuel filter is the cheaper one. It only has one line entering and one line exiting. It does not have the T adapter on the outlet side just a staight fuel line.

Fred

You are correct.... I will update the previous post.
Does the old style have a return line back to the tank.

[oemtech]

AL,

You can use any of the following:
OEM(gm#) GF481
Fram - G3727
Hastings - GF111/GF112
Purolator - F33144
Wix - 33481

The price will about $10 to $15 a piece depending on what brand and where you buy them. You can get a lot of 3 made by GM off Ebay for about $15 including s/h. The Wal Mart sells the Fram brand for about $10.

Oemtech,

There is no return line. Just one line in and one line out. There may me a return line down line somewhere, but I don't recall seeing any. It's a simple change out, so I replace it every year and have a spare handy.

[BellaBo]

Oem.... I have some dumb questions . What purpose does the return line serve? Why was it implemented on the newer models? AND.... Did you investigate if there is a standard T fitting that would serve the purpose instead of having to build one?
Thanks,

On our type of motorhome the fuel line is pressurized all the way up to the fuel rail and the excess fuel is then returned from the engine back to the fuel tank. The round trip for the fuel is on average some 40 feet.

The new fuel system returns the fuel at the fuel filter and it's called a returnless fuel system. On the new fuel systems the rail is charged with fuel however it is entirely consumed from the rail and none is returned. Excess pressure and flow from the pump to the filter is diverted at the discharge side of the fuel filter via the T and is then returned to the tank. The return line in this case is very short.

The need for a returnless system is mandated by GM emission control requirements.

In the WCC TSB 60701-T we see as an exclusion:
"¢ Any modification to fuel tank, pump, or other fuel system component.

All of that said, it is unfortunate that the OEM filter costs so much and because of that cost a need to control that cost exists and therefore seen is the DIY fuel filter mod. Given the choice to spend $10.00 or $60.00 the proper decision can be challenging and consequently in the mind of most people, a penny saved is a penny earned.
