So my 66 I6 suddenly took a dump the other day. (not DD, just sits in my garage and I turn it on every once in a while) I'm pretty sure it's a fuel issue. Car has gas, I know the carb has a leak. And one of the hoses got punctured (taped it up) I removed my carb and what I think is the fuel filter. I want to rebuild the carb myself so where could I get a decent rebuild kit for this carb. I'm not very familiar with carbs. And also, would autozone carry a fuel filter for the 66? I took off mostly everything that has to do with the fuel from the engine bay.

You should be able to get a rebuild kit from autozone, may need to be ordered or get one from Summit. You'll need the brand and the exact model number. Autozone should have a fuel filter, but it might be a good idea to bring the old one with you. It may not be a stock one.

How can I tell what kind if carb I have? It has a Fomoco stamp on it and a 6 on one side. Is it safe to say its that its the stock one?

Sound like it, you should be able to look in a shop manual and get the specs for the carb. Or just bring it into autozone and they should be able to identify it and order the rebuild kit. Ford used a couple of different brands of carbs for their cars in the sixites.

Thanks! So I took the half dismantled carb to autozone and surprisingly they had the exact one I needed. So I'm almost halfway done rebuilding. Got a new fuel filter and some hoses to replace the old fuel lines. I'll see if that fixes my issues

Well I think I'm going to need a new carb. So I rebuilt it. "Rebuilt" I guess not good enough because its still leaking and the car still won't turn on. I replaced the fuel filter, replaced the fuel hoses in the engine bay. The only thing I haven't done is checked the fuel pump. But it looks newish. Suggestions?

If its leaking, it's getting fuel. Dies it turn over and try to start or start and die? Where is it leaking from?

Easy way to check fuel pump use a clean liter jug take house off of carb and place in jug crank engine for a second if it gets about half full in a few cranks the pump is good if if it does not then the pump is bad. Easy enough. Now as someone else stated where is it leaking from? This will help us guide you.

Forgot to mention that when I was cranking it I checks the fuel lines after the pump and they were still dry as a bone. So I poured some gas in before the fuel filter to get to the carb. Started cranking it and the seals were leaking when I started cranking it. Maybe I didn't rebuild it too well because all the visible seals were wet and it was actually leaking in one of the sides I don't know what it's called but I'll try to get a picture

You've got to fix each problem as it reveals itself so that you can figure what is really wrong. If the carb is not getting fuel, then fix the fuel delivery issue (probably the fuel pump), then with that problem sovled and gas flowing to the carb, you can determine what is wrong with the carb. You can't figure it out when there are multiple issues.
What kind of rebuild kit was it? Just new jets and diaphrams. You should have torn it completely down cleaned all the varnish and replaced all gaskets and seals with new ones. It should not be leaking. Take your time and double check everything carbs can be really finicky things.

It was an autozone kit. I'll have to check the brand when I get home. I took it completely apart and sprayed everything with carb cleaner. I took a toothbrush and brushed everything with the carb cleaner. Then I put it all together and tightened it. Maybe I put too much fuel in there. I'll test my fuel pump when I get home, if it took a dump on me I'll replace it and see what happens

Another update. So far I've rebuilt the carburetor, replaced the fuel filter, replaced ALL the rubber hoses leading from the fuel tank to the carburetor itself. I sprayed the carburetor with cleaner and it fires up for a second or two. All the fuel lines in the engine bay are bone dry when I try cranking in. No gas comes out anywhere in any hoses before or after the fuel pump in the engine bay. I even replaced the line that goes from the fuel sending unit to the metal hose that goes directly to the fuel pump. When I replaced that hose fuel came out from both sides so does this mean my fuel sending unit is okay? My guess is that my metal fuel line is blocked somewhere in the middle. Is there a way I can check if its blocked? The only things I haven't replaced are; fuel pump and fuel sending unit. Any help appreciated thank you :)

Try unhooking the hose going into the carb, let it pump into a can or jug or something. Are the floats stuck in your carb? If its getting gas to the carb and its making fire, your getting close to the problem.

It only fires when I spray the carburetor with the carb cleaner but it doesn't stay on because its not getting fuel. The floater isn't stuck because I took the carburetor completely apart cleaned it all and put new gaskets and the floater moved fine. I'm pretty sure the pump, filter, and carb are fine. Like I said, I unhooked the small rubber line that goes from the tank to the metal hose that goes straight to the pump and it had gas in it, but it didn't have gas on the other side so I came to the conclusion that the metal line is blocked or maybe bent somewhere, but it can't be bent, the car hasn't been on the road for a while. Drove it up and down my driveway and towed it to the mechanics while it was running, but now it's been sitting in my garage for a while.

Unhook those lines in different places and crank it. If your not gettin gas, problem solved. Just because it has a little gas in it, doesn't mean it's pumpin enough. I'd pull the one goin in the carb and stick it down in an empty water bottle or somethin. Then crank it. At least that way you know for sure.

I'll try it again. I had my dad help me holding a cup while I tried cranking it but he said nothing came out. I'm gonna tape a water bottle and try it on every hose to see what happens. So if no gas comes out at all could it be that my fuel line is clogged?

If you do that at the carb and nothing comes out, try moving to the filter that way you will know. If you move back to the filter and something comes out, you will know something is clogged. If not, you will know its time for a pump. You already replaced the filter right?

On the 2nd try, tape your bottle behind te filter where the fuel line runs in. If it pumps fuel, you will be closer to the problem.

Filter replaced, and carburetor rebuilt. Next step is to replace the fuel pump if its not working. Then the last step is the fuel sending unit. If all fails, then I'll suck it up and replace the carburetor. Thanks, its 66 straight 6 motor. Shame it's just been sitting in my garage. Everyone loves it :D lol
