I have made progress again on my car but after installing a new fuel tank and cleaning out the carb and the line /with a new fuel filter, after a minute or so of running it starts to miss a little then progressively gets worse until it chugs to a stop. Is this a sticking float or needle and seat deal. this thing has performed perfect until now. clean it again? whats next?

Alan,

     Check and see if you have fuel in the bowl when it stops. It's very possible you've a plugged fuel filter.

As Pegleg says, sounds like it is starving for fuel.  If not, see pages 34 and 35 of this link.

You gotta have the right tools and know how to use 'em.

ok, thanks guys I'm going to get back into it this morning. It's only going to be 105 degrees today!

I've changed the filter a couple of times but I'll check it again.

ok, went all back thru the carb this morning. starts runs better-but still stumbles at idle after a minute and chugs along-doesn't die, but doesn't want to accelerate. Could my fuel pump be going out? I have the old style glass with a new filter and can see it trying to fill but it not exactly packed in there. Seems like I remember it being full when it is running?

I guess this is where I need a fuel pressure gauge?

It appears I still have dirt in the fuel line somewhere.

As a test I took off the line Before the filter and it still has some sediment in the fuel after I pump out about a half pint in a clear glass.



I have one remaining line from the tank to the inline fuel pump that hasn't been replaced. So I guess I can replace it easy enough with a rubber fuel line.



Will my stock fuel pump retain dirt or residue or will it eventually flush out or through with enough new gas?

I had same problem when I first got my TBird. It had gunk in the tank and a piece got loose and got stuck in the inlet to the fuel pump. Had a nightmare trying to figure out what it was. I tried everything and resigned myself to replace everything in the fuel system . When I took the pump and line off I saw the blockage. Been great ever since.

Al - does the Edelbrock carb have some sort of an integral fuel strainer at the bowl inlet like a Holley? 

How about the suction setup you installed in the new tank? Suction problems can absolutely kill pump capacity.

Yes, Steve the eldebrock does have two strainers at the fuel inlets-all those have been cleaned now.

I've isolated the problem down to the last piece of old remaining hard line. ( the most difficult one to replace!) It goes from the tank over the diff and between the body and down along the outside of the frame rail. Must have ben installed before the body went on.

Anyway trying this morning to get a braided line locally today to get this thing rolling. ihra and nhra only allow 10" of rubber hose and I don't think I can manage bending up the hard line to get back in there. the original line is available but, still same problem.



I can't believe how bad this line looked inside-all was working fine before I started this project. time takes it toll.

btw, the test glass of premium fuel I had in the garage overnite had about an inch and half in a 16oz. jar. It completly evaporated overnite leaving aome very fine grit at the bottom.
