As the car 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:

The original-style filter with the short 5/16" ports at about 4 3/4" long, compared to the later shape with dual ports at 5" long. With the original type having the same diameter port each end there was a 5/16" to 1/4" reducer and short length of hose to go from the supply pipe to the carb port.

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.

Showing how an earlier style filter if it had dual-size ports would end up with its central flange under the clip, which would put it in the same position as the later style filter. With the later style having a slightly tapered body I did wonder whether it work its way out of the clip, but it seems to be OK. Don't overtighten the clip to try and be sure, it may split the filter body.
