Fuel Filters

V8

The original-style translucent filter with the short 5/16" ports both ends at about 4 3/4" long, compared to the current GFE7004 transparent with dual ports at 5" long both ends. With the original type having the same diameter port each end my V8 came to be with a 5/16" to 1/4" reducer and short length of 5/16" hose from the filter to that and 1/4" from the reducer to the front carb port. The supply should go to the left-hand end of the lower type so any debris becomes visible:

North American

North American spec with emissions control equipment used a filter with HS carbs, other markets didn't get one until HIFs. The pipe extends round to just short of the filter, a Tee at the front carb takes the supply onto the rear carb: (Bill Etter)

V8

V8 as it came to me, filter unsupported:

The original filter and clip, from the Parts Catalogue:

This clip is the only one offered, but is for the crankcase breather filter, not the fuel filter: (Brown & Gammons)

But given the position of the mounting hole the clip would foul either the heater casing or the brake pipes - short of drilling a new hole and fitting a Rivnut or similar:

The capacitor clip as received ...

... too small for the filter.

But after tweaking ...

... is perfectly adequate:

Old filter showed no muck when in-situ, and only light sediment once removed. This also shows the 1/4" carb hose on the thinner section of the dual-diameter outlet port (upper-left), whereas the 5/16" supply hose is on the thicker section of the inlet port (lower-right):

Cut ends of hoses showing significant cracking internally:

Clip and old (for the moment) filter installed. In the end I had to stay with this type as the supplier I had tried to purchase an original from supplied the later type despite picturing the original:
