I got the engine today and the fuel system looks like it's the return style but it's an 05... is that right??

 

does anyone have pics of the differences in the fuel systems, the fuel lines look the same.. also will my cable throttle body bolt up to the intake of the 05, my truck is an 02

 

It should be an electronic pedal control with 4 bolt style throtle body intake. A return style is black and usually had 2 fuel lines and a regulator. A returnless is usually silver and only has 1 input line no regulator on the rail.

 

An 05' truck motor should have a 3 bolt throttle body. The 4 bolt didn't come until the 07' NNBS trucks with the exception of the LS2 in the Trailblazer and SSR. The 05' if it's from a truck should only have one fuel line going to it. Is this a 6.0L?

 

Like Zippy said if it's from a truck it should have one fuel line being an '05. The only exceptions to the rule I've seen are some of the Flex-Fuel SUV's.

 

Thanks Zippy!

I dont deal much with the electronic TB set ups. I had thought they were 4 bolt and didn't relize they were a 3 bolt like the cable style.
