so my 3.4 swap is nearing completion and i just wanted to know how people got fuel to their 3.4 pics would help ive read and researched a couple methods from making a hardline all the way from the fuel filter to the motor to just using the fuel line from the donor truck. i just want to know what worked best for people and to see examples.

 

I just spliced the old line to the one on the 3.4 with a high pressure coupler and have had zero problems.

Used one like this, with heavy duty clamps (not heater hose style clamps): http://www.fittingsandadapters.com/pushonunion.html

 

I am doing mine like RobD said. Here is what I did. The gold line on the left Is your return line I attached that to the intake plenum and to the right is your high pressure line to the fuel rail. Here is a close up of the return line. It ussually goes around the corner but now its routed back to the passenger side. Hope this comes in handy.
