350SL not staying started

[VickMorrow64]

it starts right up with turn of key then just dies before I apply gas
Had a fuel hose leak and mechanic said about 5 gallons spilled out
I saw the puddle it was huge
Put 5 gallons back in car and now cant figure why it stalls
Have had this car for years and it always started right up and stayed running
had mech change bushings on throttle linkage
only thing I can think of - is perhaps a fuel screen coming out of gas tank - does this model have one and do they plug up easily?

perhaps a vacuum line?

any help is appreciated
