Cannot find fuel filter.
This is my first post. I am having a very hard time finding fuel filter and figured i should ask the experts. My manual says it should be on the fuel pump or carb. inlet. Most internet sources say the same thing but they both appear filterless. My truck is having hesitation problems on when driving but not sitting in neutral. It has 4 speed. I bought the two fuel filters that came up on the computer at autozone and cannot find anything that looks like either one. I posted pics of the carb, pump, and a thing that looks like a fuel filter but has a wire connected to it as well as the things i bought at autozone. Any insight would be a huge help because i am at a complete loss. Thank you.

Look down the throat of the carb with the engine off and open up the throttle. See two solid streams of gas shooting at the boosters? If not, either your accelerator pump diaphragm has hardened up, or the accelerator pump check valve has gone bad.

With no filter the carb is probably trashed inside, from accelerator passages, boosters, transfer tube, needle & seat... all of it.
For an FE engine I recommend 10-12 degrees BTDC with a stock engine.
Make sure the vacuum advance is hooked up (set timing with it disconnected though) , which I see a vacuum hose connected to the port, just verify.

I was kinda thinking the carb was gonna need service anyway. Everything seems to point to a fuel issue.

Somebody put a Holley on your truck. It looks new enough, so it probably only needs a needle and seat if it needs anything. What it REALLY needs is for a person who knows Holleys VERY well to tune it to the engine. Holleys aren't like Edelbrocks. Just because it's brand new in the box, DOES NOT mean it's tuned to the engine. A hesitation off idle is a very common problem with Holley carburetors and it can be tuned out. Just don't take it to some yahoo that thinks he's a carb expert. Take it to someone qualified.

I saw that too. It looks like a manual choke that doesn't have the cable run. This will cause cold-start issues even with a carburetor rebuild and proper fuel filter.

A lot of Holleys have the fuel filter internally where the fuel goes into the carb. Disconnect the fuel line and remove the large 15/16" ??wrench size filter housing.

The Edelbrock carburetors are more forgiving than the Holleys, is what I was trying to say. I think the Holley is a better carburetor because of it's tunability.
As far as the choke goes, yes it should be hooked up. Yes, it may have a slightly worse flat spot when cold. NO, it's not the end all, be all problem. I've milled plenty of choke towers off of Holley carburetors and still drove them with little issue cold.
