4616 vs 4604 fuel filter install

Getting ready to do oil change and fuel filter change. I searched around regarding the new 4616 fuel filter but could not find an answer to a question I had. Does the new o ring end still snap into the cap on the frame rail filter? It looks bigger in diameter, maybe it surrounds the cap flanges?

That's a good question that I can't answer since I don't have those anymore. It is a totally different looking filter than the 4604 but I can't see a picture of the top of it. Does it still have the small nipple that snaps into the cap? I wouldn't think that it would install any different than the filter it replaces. It's supposed to be a "direct replacement".

The new o-ring is on the opposite end of the filter from the cap. Installation is no different than the 4606...it still snaps in.

Thanks fellas, I have been stuck at home for a month after surgery so I could only look online at this item. Went to O'Reilly and looked at it, it does have the same clips for insertion in the cap.

Heading to International soon to get theirs, O'Reilly sells a "Microguard" brand fuel filter, it looks like the OEM, but I don't trust it.

Stick with OEM only on the fuel and oil filters.

Good choice... the filter you saw at O'Riely's is not a true OEM filter... it is a "will-fit" filter made by someone else. It may fit, but to get around the Racor patent, it is either sized slightly differently or does not have the same filter media or the Aqua Block membrane (white mesh looking media) on the outside of the large HFCM filter.

Buy OEM made Racor, Motorcraft on-line or at the local Int'l truck dealer... which is where I buy my fuel filters for less than half of my dealer (something like $37.00/ea (can't remember as I buy 6 at a time so I have them).

The one at O'Reilly did have the gauze cover but again it was an off brand. I have always used the Fram oil filter, it has the patent numbers, so I go with it.

Hard to say...

The background story is "buyer beware"... and it is difficult to know what your getting.

Racor is the OEM manufacture of the oil and fuel filter housings that are used on the Int'l motors (in this case the 6.0L PSD). They make their filters to fit their housings and have a patent on them.

Racor makes filters for other people, but there are so many "will-fit" copy cats that no one knows which ones are OEM and which ones are not???

Some "will-fit" filters look like OEM, but are not due to size differences and filtering capability.

The oil filters are easier to identidy due to the patent numbers on them and that Framm and Motorcraft are readily available at Walmart and are made by Racor.

The fuel filters are not so easy and have no "patent numbers" on them... so for safety sake, many of us by from sources we know that sell only Racor made/brand filters... and advertise such.

The O'Riely's brand/product may very well be a private lable filter by Racor... but I for one without knowing 100% will not use it... not when I can buy Racor filters on-line or at my local Int'l truck dealer.

Hopefully that answered your question or the "background story"?

6.0, as I understand it, there is an additional o ring on the end of the filter for reducing water contamination in the fuel...that may be not the whole story but it is what I think I know.

If the filter becomes blocked, the extra connection and o-ring prevents unfiltered fuel from by-passing the HFCM filter.

The Motorcraft fuel filter #4604 does indeed have a patent # on it. Patent # 6,495,042 molded on the face of the end cap of the secondary filter. The primary filter is identified with " Pat. Pend. >PA6-GF33<

Thanks for clarifying... there we have it... just check the O'riely's fuel filters to see if they are stamped with the correct patent numbers as shown above... if so... they are buying from Racor and putting in their own box.
