Where should I put the external fuel filter?
1964 Impala SS
4 bbl 327 I am just finishing up the fuel system.... fresh tank, fresh rubber however still stock metal lines. SO, here's what I've done Got the tank cleaned by a radiator shop. Done and done. I removed all the rubber fuel lines, sprayed the hell out of the metal lines with carb cleaner and blew compressed air through them SEVERAL times. I replaced all the rubber with new 3/8's line.... Got a fresh carb rebuild on there and so on. NOW, as a precaution just in case there is any extra crap in the lines I did not get, I am running a separate temporary filter.... Punchline: Does it matter where I put that filter? I was told I should put it before the fuel pump however it is a VERY tight angle from line to filter to pump and its putting a kink in the line. Can I run the filter from the pump to the carb and still get the same results?

I prefer to run my filter between the pump and carb, incase anything in the pump breaks loose.
What carb are you running? If a Qjet, you can use the one behind the fuel inlet. They work fine, especially the long ones.

Any reason why I would need 2? Just outta curiosity?
And the filters look like this.... well, plastic, and the inlet/outlet is on top....

 I ALWAYS run two filters. One on the frame rail before the mechanical fuel pump and one between the pump and the carburetor.  The one on the frame rail catches anything before it gets to the pump. The other one is just INSURANCE

lol, thats what I was basically looking for was the insurance portion of it.
NOW, from the hard line to the filter is a pretty good angle and is putting a kink in the line.... best way around that? Run longer hose or can I get an angled fuel line? I don't want to run a long hose b/c of A. Clearance and B. I don't want the fuel filter flopping around.

yupp.. that and most stock fuel pumps have filter screens.. when they clog up, I hate changing them. run a simple in line filter b4 it, and it will never get debris in it. one between carb and fuel pump, just for precaution

Ok, no problem. I'll go get another filter tonight. Easy sneezy....
But that is a straight shot from pump to carb. Run that inline no problem. How do I overcome the angle from the hard line to the pump

Ok, I just put one filter before and one filter after....
Technically electrical question though. I think the wire gauge I have for the electric choke is one guage size bigger than the wire guage coming from the choke.... Is this a problem? Its about 8 inches from the choke and then another 3 feet or so of the thicker guage. I was planning on hooking the wire to the starter.... sound good?
