yeah i got power so im gonna go ahead and replace the pump.

more dumb questions, if my truck has evap, where do they hide it?

all the parts stores are asking if i have evap, i guess there is a variation in the pump if i do or dont.

 

Yes, the evap canister is under the bed next to the gas tank. If you do have it, It will have a pressure sensor on the pump for the evap system. Thats the difference.
Good luck with the swap.

 

That's funny, I've never heard of a 96 or newer North American vehicle without EVAP, I thought it was a federal regulation?

 

found out i do have evap.

it was to dark to see under the truck, so i ran the vin on one of the gm websites.

pump is in, working perfectly, thanks for the help guys.
