i am finishing up puting an lt1 from a 94 caprice into my 86 z28 and and was wondering what the best solution for putting lines and a fuel pump in. i am planning on buying a decent external electric pump which i was planning on mounting in the area where the filter goes. the problem i have is the lt1 came with the "plastic" lines and i am not sure what i am supposed to do about it, seeing as how the part where they come off the fuel rails has the attached plastic lines. i do have the whole line setup from the caprice so i suppose i could try and use that but i dont know how to splice the hardline from the tank into the plastic line.

 

does anyone want to share what they did to install the fuel lines?

 

There is an LTx swap subforum (along with LSx - sorry, co-mingled) that has the answers. Moving there now.

Also check out the sticky, in the top section of the Engine Swap and the subforum.

 

i used efi rubber hose to replace the plastic lines, and where it had to connect to the hard line i used 3/8" pipe thread hard line adapters that can be picked up at your local auto store. I'm pretty sure mine came from a transmission line fitting (lol). To go to the tank and fuel filter i used dorman replacement quick connect fittings. they sell them in 5/16" and 3/8" and were about 8 bucks each. I double g-clamped every line that involved rubber and connected up to the stock stuff no problem. No leaks, no empty wallet, no problems after a month of daily driving
