Fuel Vaporization Using Eddy Carb -- In-Line Fuel Pump Question

I have run a Thermoquad, Edelbrock 1406, and now a 4777-2 Holley Double Pumper on my bone stock 360.....with a stock $17.00 mechanical fuel pump....no issues....now logged over 35,000 miles in the last 2 years.

How about this for some confirmation?

I have a new Spectre Fuel Tank....new Chinese sending unit...original fuel lines...1974 Dodge Dart Sport....who knows how many miles I have been using the same gas cap.

Vent Nipple on the Fuel pick-up/sending unit....capped off.

No charcoal canister....removed..deleted.

1/4" inline clear plastic fuel filter before the carberator.....between pump/carb.

.375" Edelbrock Carberator Insulator Gasket, square bore, or spread...

Heat crossover blocked off.....and I dont run a choke at all...

Never had vapor lock, fuel boiling, nothing......and it gets to over 105* where I am...and I dont baby, my baby....if its running., we're rollin.
185* all day long....will get up to 205-210* in standstill traffic...still not a hiccup/burp/fart or stall.

(seen some similar situations before)....turned out to be incorrect float level....and another "only when hot" situation that turned out to be a worn out ignition coil.

Its hard to diagnose a problem without checking basic stuff and knowing the condition of the parts your dealing with.

Could be the ECU box breaking down..........
