Thinking of buying 2003 chevy 2500hd with quantum cng system , have trucks with impco systems that i like, could someone tell me if these quantums are good systems and can i find parts for them thanks

Quantum, Impco same system just a different name. '03 should be a 6.0 litre which is fuel injected. Good system that should provide troublefree operation. Parts are around but starting to run low on some items. Shouldn't be too hard to keep it running.

I've enjoyed my '03 Silverado.
