Engine starting and running troubles..

my press dropped one day while passing a guy my motor normally ran 75 psi with a high volume pump she dropped about 10-15 psi and at an idle it runs at about 15 psi but will go up with the revs, as far as the fuel pump i just changed my oil and it did smell alot like fuel but i think it was from being flooded, and wasnt drastic like yours,
i just swapped oil in her, and shes still doing the same thing just not as drastic as far as the holley the secondairy side of the cab is leaking fuel through the venturi's so i threw a clamp on the second hose and it seemed to stop the excess fuel, but it still wants to die??
as far as motor its an oldie and has a burnt out exhaust valve which im replacing the heads in a couple weeks with good compression minus the one cylinder, and has always run like a top until now, no smoking, ticking ect, i didnt touch the plug wires and they haven't been messed with for a while now...and its been in the car for five or soo years now give or take, ive had to swap out ignition modules a couple times before for no reason though

im going to throw on the eddy, if that dont work then the carter avs... and ill let you guys know whats up
