You are right - it probably had filters...
The original Factory Part #3878261EH List-3310's and the over the counter Holley 3310-1's were 4150 type carbs with Center-Pivot floats and had a 7/8-20 Inlet fitting and a filter behind it. Sort of like a Rochester
as 'Oger' said - matter of fact the filters and springs will interchange...
The later (3310-2~?*) over the counter units were a 4160 type that used a rear metering plate v.s. the metering block with servicable jets. They have a smaller 9/16-24 or 5/8-18 size Inlet thread size. These were also down-rated to 750cfm v.s. 780cfm for the earlier version.
* there must be at least 8 versions so far
About the only parts the 4150 and 4160 versions of this carb. tend to have in common is the '134' Main Metering Block.
You can still get a kit from Holley to replace the filters and the springs.
It is part #162-500. It includes both front and rear filters, 2 springs and all the necessary gaskets for under the Inlet fittings.
The 7/8-20 Inlet Fittings are also available from Holley still. Part #26-26 will get you the correct fitting to adapt the standard 5/8 fuel line fitting to the inlet filter retainer.
There are also sizes for all the common 1/4, 3/8" & etc. inlet lines - ask the rep to explain them if you need a different size.
As for a fuel line - Summit sells the "Sergi" line of fuel inlets for Holleys and they have an 'adjustable' one! Part number from Summit is #G3121 and they are under $50.
Summit probably has the fuel filter pack in stock also - although, like lots of other parts, they don't list it in their cat.
Hope some of this helps;
