Fuel Line location and fuel filter types
#1
In checking the carburator I noticed that there wasn't a fuel filter installed. Strange. My questions are:
1. Can any size or type inline filter be used?
2. Does the fuel line run on the alternator side of the engine as you can see in the picture? If not where should it run and can you bend the fuel line pretty easy without rupture the line?

There is a factory fuel filter on the fuel sender located in the fuel tank, but more is always better.

1. Can any size or type inline filter be used?

As long as the fuel filter input and output match the hose size your are using its fine. pretty much 90% of the fuel filters will be fine.
stay away from glass filters they can be dangerous. I use a inline aluminum canister fuel filter right before the Fuel pump inlet from the fuel tank where the fuel line comes from the engine bay apron to the fuel pump.

2. Does the fuel line run on the alternator side of the engine as you can see in the picture? If not where should it run and can you bend the fuel line pretty easy without rupture the line?

I've seen cars that have it either on the left or the right, I'm not sure if it depended upon a A/C car or not.
my car the fuel line goes from the fuel pump to the Right side(alternator side) because i have a A/C compressor on the left side.
I know when i tried to order a replacement fuel line it was shorter and wanted to go to the left side where the A/C compressor is, it was impossible to use that fuel line. I went back to what i believe is the original 351-2V with A/C fuel line which goes to the alternator(right) side. i've seen cars that have them on either side but i'm not sure if original A/C cars had the line going to the alternator side or not. Personally i like the fuel line on the Alternator side because its easy to hook it up to an aftermarket Carb and gives me clearance for the coil mount on the left side(a/c pulley)

Hi, I have the glass fuel filter. Why are they dangerous? Just curious,never had issues in one year.
Thanks,

I had one once that didn't seal right at one end of the glass tube and it leaked.

I've been using the glass filter about 6 years without any problems with breakage or leaking. Since I have replaced the fuel tank and pump I'm not seeing any more debris, so I am thinking about removing and just leaving the stock filter at the carb. The glass is very thick, so I think it would be hard to break, but probably better safe than sorry.

glass filters have gained a reputation for being dangerous, due to cracks, or not sealing correctly they can leak.
if an engine fire breaks out, there is a chance for the glass to explode and set the main line on fire.

they are banned at local tracks, and some shows in my area have banned them due to insurance risk.

personally I've never used one, i've heard stories good and bad, i think for a short term diagnostic look at the fuel system they are a good idea, but after the problem has been corrected a different one piece fuel filter should be used in its place.

"if an engine fire breaks out, there is a chance for the glass to explode and set the main line on fire."

And a filter with a plastic housing attached to a rubber line is immune to combustion, clearly.

i never mentioned plastic.

i can tell you a story relayed to me about a guy that used a pyrex plastic filter which cracked due to engine heat and began leaking.

personally i use a aluminum one piece filter.

use whatever you feel comfortable using.

Fuel is pretty stable and its takes a little more then it leaking for it to suddenly combust.

I'm sure many of us have discovered the wonders of a leaking holley fuel bowl with a puddle of gas sitting within the intake risers or an accelerator pump springing a leak.

I use a filter like this

and its installed right before the fuel pump where the fuel line comes through the apron.

i think a lot of problems with regards to 2 piece fuel filters causing fires is people cross threading the bowls and creating a small leak. most people also install the filter in a place that is easy to see and service so its usually sitting somewhere on top of the engine, should a leak start it will eventually run down the motor increasing the combustion possibility as the gas vaporizes over the hot engine.
