Either a 1.6 Liter 2 barrel carburetor 4cylinder engine with single over head cam found in 76% of that years dodge colts. or it's a 2.0 Liter 2 barrel carburetor 4 cylinder engine with single overhead cam found in 24% of 1974 dodge colts

It all depends on what engine is in the car.

2.0 liter single overhead cam (SOHC) engine.

1600cc or a 2000cc engine, 1.3liter or a 2.5 liter i do believe.

If i'm understanding your question correctly, then you're referring to engine displacement. Engines are measured by displacement, usually expressed in liters(L) or cubic centimeters (cc). Displacement is the total volume of all the cylinders in an engine. An engine with four cylinders of 569cc each totals 2276cc, and will be rounder off and referred to as a 2.3 liter engine.

comment on any drive line work done recently as this problem has not occurred before so it is suspicious
drive axles are different lengths and if the wrong side axle is fitted , this problem will occur

TAKE THE CAR BACK TO THE SHOP THAT REPLACE FUEL PUMP

i would say yes, they probably listed the exact displacement in cc's which times 1000 gives you liters. it would come out to 2.74 liters and manufacturers usually round up to the next whole number so i would say that 2.8 sounds right.
