Default Fuel Filter Question

I am working on a '66 327/300 which has a metal fuel line from the fuel pump to the carb. I have seen a number of cars with fuel filters just below the high point where the line bends, in a vertical position. To add the filter do people just cut out a section of the metal line and install the filter with some rubber fuel line and clamps on the ends? Thanks.

You often see them on the frame, right before the line enters the pump.

Thanks, Dan. I bought a line to go from the pump to the carb and it is 1 piece. This is apparently correct for the '66 and '67 300 hp, but the '63-'65 300 hp models have a 2 piece line from the pump to the carb - I assume to accomodate the filter. Did the '66 and '67 300 hp not have an in-line filter originally? I was told by a guy at Zip that I could add a filter that goes inside the carb. So I guess my options are: get a 2 piece line from '63-'65 or some other year and hope the line is workable (length and routing); put a filter in the line before the pump; cut the line I have and install a filter between the pump and carb as I originally mentioned; or, put a filter inside the carb. Not sure which option is best, although I have seen a number of people who think between the pump and carb is preferable to before the pump. Happy to get any input on these. I'm not worried about being "correct" at this point - more interested in something that works well and reasonable to install. Thanks again.

what makes you think you need a filter. a lot of cars have been running fine for the last 40 plus years without one

The fuel filter on your 66 would be internal ( in the carb). You don't need the external like the 65 with the Carter AFB..

Well, actually "no". I think he may not have realized he already has a filter in his carb. I don't know how many cars have been running fine with NO fuel filter at all. Even my 56 Oldsmobile has a fuel filter, atlhough the OIL filter was optional.

Yes the early carbs do have an internal 'sintered' bronze filter at the fuel line inlet...however an additional paper filter is a plus. Running with no filter at all is a very bad idea...for instance...more than one C1 owner here has had their fuel sending unit 'sock' disintegrate in the tank over the years and make its way into the fuel system with a resulting mess in the fuel pump and/or carb(s)...

I have also never heard of one of the glass fuel bowl filters breaking on its on...and similar filters were used for years on many tractors doing heavy duty farm work...

If you have the correct Holley 3367 carburetor, it has a replaceable bronze filter inside the fuel inlet; you don't need an external filter.

Plus, when you cut a perfect, non-leaking metal fuel line, there is always the lurking danger of the rubber line coming loose (as the OP proposed using rubber). Seems a bit more dangerous up close to the top of the engine versus the rubber one from the line to the pump. I had one come loose one time with 2 clamps on each end where someone prior to me had added an inline filter. The rubber line on my 65 (327/350) going from the filter to the carb has always made me a bit nervous, but I have screw on clamps versus the spring ones it had from the factory. Just gives me a little more piece of mind.

John, any idea of why they used rubber from the filter to carb on some setups, and metal all the way on others (similar Holleys included)?

I don't know, but they never made that mistake again; it was only done in '64-'65 on the 350hp and 365hp engines with the Holley 2818.
