The original fuel lines were old, deteriorated and needed to be replaced. I decided it best to install nylon fuel lines. I had several feet here and, of course, I had to drop the fuel tank. Ugh.
As you can see, this is the original pressure, return and vent lines on the 88 tank.
I will have to modify two of these. I'll leave the vent line as is.
I removed these 90° fittings from the donor car but you can get these at your local auto parts place.
The item on the left is the pressure line that I cut off the tank.
I used a 3/8" compression fitting and adapted the newer line as seen.
The same procedure was used for the return line with the exception of using a 5/16" compression fitting. Voila!
Here, the fuel tank was reinstalled and the new nylon lines were clicked into place.
I'll secure and tidy the wiring up later in the day.
I decided to use a fuel filter from a 95 Cadillac DeVille with the Northstar engine.
I liked the fact that it had both ends made for the quick release nylon lines.
A view showing the filter and line routing. I still need to make brackets to hold the filter and lines.
Here's a view showing the fuel lines where they connect to the engine. In time, I might relocate them to the other side of the engine for a cleaner look. Until then, this is where they'll stay.
I kept the original stainless lines because of the schrader valve. This way, I can verify and relieve the fuel pressure.
After putting in $20 worth of fuel and cycling the ignition a few times, I can verify the following:
-The Walbro fuel pump works as intended.
-The Frankenstein fuel sending unit works perfectly.
-All fuel line connections are leak-free.
