Title: 5.0 vs. 3.8 fuel lines
Post by: MeanLX on April 03, 2014, 11:12:50 PM
Can anyone tell me if the hard lines for the 3.8 Birds are the same size or different from it's 5 liter brethren?

I dunno always walked a wide path around the 3.8, but if it helps, the 5.0 lines run up the RF corner of engine to the fuel rail... The 2.3 come up the driver side toward rear of engine, wouldn't surprise me if 3.8 was different as well...

The Turbo coupe and '88 5.0 cars are routed differently in the rear due to dual lers...

87-88 5.0 fuel lines are routed the same. Odd when the 87 5.0s had single exhaust.

The '88 3.8 lines come up on the passenger side, near the air intake plumbing They come through the inner fender, at least on my two '88 cars they did. They're not a direct "plug and play" with a 5.0 fuel rail, but they are close. A few folks here have adapted TC fuel lines to work with an f150 v8 fuel rail. I don't know what's involved with creating a section of line to connect the two. Might ask about the "how" part of it.. ;)

I have no clue if the older V6 cars were like the '88 or not. Probably not, as the '88 was the first year of the SEFI 3.8 and not the CFI version.
