My 1970 Super Bee 383 A31 car

New Edelbrock AVS2 650CFM is a noticeable and immediate improvement over the old Holley Double Pumper. However it is idling higher than I would like and adjusting the idle screw did nothing so I may have to toy with the timing a bit.

You are going to retard the ignition timing to drop the idle speed?

The entire log kept by the previous owner is him messing with the timing. Pages and pages of logs on timing changes with the occasional oil change, filter change, or other small job. But mostly timing. No idea where it even is right now. First thing we did after setting the original carb, which did not improve the idle, was retard the timing by ear. Just the tiniest twist fixed everything. Don't see why it won't this time. As above, adjusting the primary idle screw on a brand new factory set carb did absolutely nothing so that's the next logical step to me. Otherwise the car ran pretty good.

A friend of mine (R.I.P.) was a multi-millionaire. He drove a used 20 year old Pontiac Fiero until he wore out the second engine and the frame was rotted out. He bought another one and drove it a decade!

I knew a guy like that ...he died last year worth over $22 million. Wouldn't buy anything new if he didn't have to.
Always after a deal...no matter how cheap the job.

Decided to track down the fuel smell. Now the car is in the garage it’s very noticeable. Discovered leaking junction back at the tank. A couple lines right next to each other on the driver side with hose connecting the metal lines to the tank. Manuals is not very clear exactly which ones they are but whatever 3 inches of hose is 3 inches if hose. Fix it tomorrow.

Well that sucked. Was determined to get it done despite the hoses dripping a lot of fuel onto my arm and quite a bit on my face. Arm feels like a burn victim now. Eye not doing great. But finally got the small old hoses loose and replaced. By the time I got it on everything was slick and the clamps kept spinning. A real nightmare since there is zero room for maneuvering your arms under there (I do not have a lift and did not want to jack it up since it is a full tank and would just spill more). Not thrilled with the results but I'll get some jacks and do a cleaner job this winter. At least it's not dripping anymore.

These are what was leaking. The one on the right the most. I'm confused. Why would this leak so badly? Unless I am reading this wrong? The arrow on the bottom left is pointing to the fuel pump, not the gas cap, right?

Useful.

Mine don't route into the trunk. I'm not even positive where they actually end at. Very hard to get around in there with the car on the floor. I think they just cut it off when they did the trunk pan and left it. But they leak.

Fuel pump is on the engine, not in the tank!

Every other car I've worked on had a fuel pump in the tank. Stood to reason the disc cap with two lines running out of it was an in tank fuel pump because that's what they all look like.

I should add.. in that factory diagram you are referencing at least! Who knows what you may actually have..

The weeping vent lines at the tank is becoming the biggest problem yet. Return line is run to the short vent instead of the sender unit for unknown reason by previous owner, which functionally makes no difference as dumping fuel direct is dumping fuel direct, but seems to have caused some pressurization by denying the tank the appropriate venting and reducing it to one vent. Don't have the space to pull all that and install a new sending unit now that winter is here so I'm opting for a vented cap to restore venting and going to try driving the gas level down lower than the vents. The real problem is the smell. The garage is a gas chamber and now the house is smelling like gas even after I soaked the clothing I wore during the job in the shower for two days, washed it, and rewashed it in the heavy soil 2 hour option. Still reeks. Now the washing machine reeks. And I washed my dog's bed with it so my dog's bed reeks. TWICE. I do not know what I have to do to get the stench of this non ethanol gas out of my life, it spreads to everything that comes in contact with it, and the lady is growing increasingly impatient about it but there's NOTHING I CAN DO. I hosed out the garage floor, I, did the wash multiple times, I replaced the hoses and clamps, washed it all down, but it stills smells.

Another bummer of a day. Discovered all of the nice Edelbrock stuff (8131 pictured and 8123 stainless line) I bought to connect my new AVS2 to the vapor separator won't work because the M1 dual plane intake manifold blocks the fuel filter. No working around that. So I'm back to square one and $100 poorer for trying and still have to figure out how to run these lines and what to buy. I have all the stock metal lines but they won't help unless there's a slick way to connect that small gap between the line and the carb (pictured). I suppose a small length of rubber might suffice but feels cheap. Kind of wish I had just repaired that Holley but it was giving me so many headaches with leakage and then the dumb base ears cracked off so I was over it.
