fuel is not getting to carb.
Hi, I got the points set, new filters, ect, engine will run if I pour starter fluid down carb. I removed the fuel line from carb and no fuel came out when I turn over the engine. Yesterday I installed a clear fuel filter inline of the tank and fuel pump. When I installed the fuel filter yesterday a few drips of fuel came out of line but then it stopped dripping. After I started engine the clear fuel filter filled full with fuel. Does this mean the fuel line is clogged?

But if the float was stuck wouldnt there be fuel shooting put of steel line at carb? I think its the fuel pump but its strange that the fuel filter filled up.

the fuel should be comming out in gobs while cranking.. anything less then there is a fuel system issue. clogged line, tank pickup, fuel pump, kinked rubber line....

It was running when I bought it. It has not been driven for 20 years though. The guy couldnt drive it since its brakes currently dont work.

"Yesterday I installed a clear fuel filter inline of the tank and fuel pump" Are you saying you installed a fuel filter before the pump? Any additional filter, other than the one in the carburetor inlet, should be between the pump and carburetor. Try disconnecting the line going into the pump, remove the gas cap, assuming your tank is close to full, the gas should freely run out. If it does you have a clear line and a bad pump, if it doesnt you have a blocked line.

If not. The post above (removing line to pump to see if fuel flows) is an excellent simple troubleshooting step.

Also, I know it's crazy and would be a coincidence, but take off your fuel cap and see if you have any fuel in the tank (you mentioned that you only got a little when you installed the inline filter).
Make sure that the cap is vented too. Better yet, try starting the car with the cap off.

Interesting, so its possible that air is trapped in the lines, and with the cap on the air is stuck in the lines? Sounds possible, I'll try it and see.

With the fuel line off the carb, use a funnel and some hose to pour fuel into the carb. This should let the engine run 30 seconds or so. Put the end of the fuel line into a clear jar. Start up the engine. Hopefully it can purge the line like slow cranking won't plus you can see if anything is contaminating the fuel.

Thanks guys! I pulled the gas cap, then flooded the carb and went into a smooth idle. After a minute I checked fuel line at the carb and it was wet with fuel. I cant idle it too long since its in my garage backwards and the fumes are pretty bad. Ill be able to idle it this weekend to know for sure the fuelpump came back to life.

You need to start a new thread so more people will read your post. Your ECM will only power your fuel pump if there is oil pressure present so you might have a bad connection at your oil pump sender (about 3" to the left of your HEI) and your ECM is assuming you don't have oil pressure. Take the plug off and spray some WD-40 into it then plug it back on and off and on and off and on several times.
