1970 duster slant six stalling problem

[travism]

Hello I have a 1970 duster with a slant six and when I drive it starts to bog out and stall especially when going up hills, also I noticed that one of my exhaust pipes on my car is sputtering, any info would help Thanks!

Classic symptom of fuel starvation, fuel filter, pump, tank contaminated w/ rust/dirt etc., tank breather clogged........check the oil for gas smell/contamination, a leaky pump
diaphragm will trickle fuel into the crankcase before it gets bad enough to hose out the vent hole....................................

I'm not sure what carburetor you have, but if it has one, I would check the float adjustment. If the float is too low then the fuel will slosh away from the jets and starve the engine of gas.
