Before installing the new hardline, we had to cut the plastic holder in the mount to fit the larger line.
The new -8AN hardline fit very nicely along side the factory hardlines.
We installed the factory black plastic fuel line cover and the larger line is hidden and protected compared to running a braided line the entire length of the car.
We used the Earls -8AN Male to ½” Tubing Adapter to attach the -8AN hose to the ½” hardline. This fitting is rated to 25opsi and uses a brass compression adapter that squeezes onto the hardline when tightened to provide a leak-free, solid attachment without the need of flaring the line.
Out in the back of the car, the hard lines terminate just before the subframe.

I am still here, consuming every FD update. This thing gets more awesome with every post!
Thank you 🙂
Great series. What’s the story with aluminium fuel hardline and ethanol-based fuel? My (limited) understanding is that aluminium needs to be anodised at minimum to protect it from the jungle juice.
Yes, ethanol can corrode aluminum, particularly when it contains water or in high-concentration blends The alcohol reacts with the metal to form aluminum alcoholate, causing white, chalky corrosion, pitting, and potential, severe damage to fuel systems.
Thank you. E85 is hygroscopic and will absorb water which can lead to aluminum corrosion only if it sits for long periods of time. Raw ethanol is generally safe for aluminum. Since we will not store or let the car sit with E85, running the aluminum hard lines will not be a problem. We will also be running drums of Ignite ethanol, so that further reduces this concern.
Very cool updates.
As part of the testing you’re doing for the single pump setup, how does the cost of making the larger aluminum fuel feed line compare to adding a 2nd fuel pump and using the stock feed line?
There are many solutions to a given problem. We wanted to find the maximum power the 415 LPH DW400 fuel pump can support on a rotary without fuel line restrictions. Once we reach that point, we will turn to a brushless single pump solution based on the layout of our fuel starvation solution in the previous article.
