fuel filter

any other fuel filter styles/brand correct for 66?

[Bob Gaines]

The Rotunda marked filter was early and then like a lot of parts the trademark transitioned to FOMOCO. In this case the trademark skipped right over the Fomoco trademark to the Autolite one. I believe the Autolite marked filter was for much later 66 production and all of 67 GT350 production.

Bob when do you think the versions with the part number and logo were stamped into the metal were used or came into usage?

Know we went through this subject and similar posted pictures before the big crash.

C5AE version





C7AE version

Jeff,late 67 is my best guess . The C7 marked filter is a FG15 by the thread . I am not sure what the C5 marked filter is . For those reading the FG 15 was the one used on the GT 350 needing a adapter.

The C5 version is a FG-15 also.  Don't think we settled on it last time we discussed these in that older thread.  Interesting piece at least

FYI for those reading the metal stamped version was used up to most of 69 production. That is when the C5 black ink stamped filter came into use. They typically have very late 69 production date codes. With that said those filters a incorrectly used on some earlier concours applications. The one in the picture date code is 37th week of 69.

where does the silver body filter fit in?

Of course the black ink versions are dated for 1970 production and not relevant to 1966 assemblyline production. The silver and gold finish may be a matter of a different vendor . I have seen both otherwise identical . The gold which is over the silver has a higher corrosion resistance .

Jeff on further reflection about the metal stamp filter I would think that they may be a different vendor then the ink stamped version. They were probably used at the same time as the ink stamped version. Also the C5 metal stamped version I believe would have been used earlier in 67 production along with the red ink stamped style with the C7 stamped version being the updated version that came out in later 67 well before 67 production stopped . My speculation in the C7 stamped version regard is reinforced by the need for a change in engineering number to the C7 . If it evolved later it most likely would have a C8 engineering number. I cant tell the difference between the two (C5 and C7 )other then the engineering number. Curiously the black ink stamped versions continued well into 70 production with the C5 number. This makes the most sense to me until more compelling information comes along.

Based on old discussions on the previous forum and also the Concours forum, my understanding of the C5AE ink stamped filter timeline is...

65-mid(?)66 - Silver body/Red Rotunda ink stamp
later 66 - 67 - Silver body/Red Autolite ink stamp
68-69 - Gold body/Red Autolite ink stamp
69-70 - Gold body/Black Autolite ink stamp

Is that still generally correct?

Thanks,
Dave

Revised stats-      65-66 - Silver body/Red Rotunda ink stamp
later 66 - 67 - Silver body/Red Autolite ink stamp , Gold body/Red Autolite ink stamp , Gold body C5 marked Autolite metal stamped 
67-69 - Gold body/Red Autolite ink stamp,C7 marked Autolite metal stamped
70 (Mustang)  - Gold body/Black Autolite ink stamp
Until more compelling information presents itself.

Phil,I don't recall seeing that style on a GT350. It could be another vendor in the same time period but more likely IMO a earlier version. Maybe someone else has more insight.
