Give me fuel! give me .... anything but fire.

I was moving on to complete the fuel system. There were a few tasks remaining. One was to complete the filling neck. The second was to run the supply and evap lines to the engine. The strange thing is that I did not take any pictures making the filler neck. Therefore, I am not going to spend much time on it. It was basically cut at the right spot. Insert the hose between the two cut off parts. And have a cold one.


Of course, it was a bit more involved but really nothing to write home about.

The fuel lines were a bit more interesting. First of all, I did some planing. I am quite proud. I rarely do planning. Due to the location of the lines, the fuel filter could not be easily mounted. That was one of the reasons for the battery relocation box. That box will also act as a fuel filter support bracket.


I replaced the old mustang filter with the fresh one. I got this thing from Part Source and, unlike the old filter, it did not have the flow direction arrows. I had to put them on myself to avoid placing the filter on backwards.This location worked out really well. The hoses were not forced into place but maintained their original bends for most of the time. The hard fuel line was bent to work with this location of the filter and therefore worked perfectly.






Taking pictures from under the car with the light above does not work well.





Here you can see the thicker metal line routed along the brake lines. The hose is the evaporation line that I got from NAPA. Both, the supply fuel line and the evap line are running along with the brake lines. In fact, I used some of the funky mustang plastic mounts that hold all the lines together.

In order to know the required position of the fuel lines at the front I had to put the motor in to see where the lines should be.





At this time, it was just a dry run the motor would have to be pulled out later.


It was a good exercise and as you can see the perfect location for the fuel line was found. The supply line come up from under passenger foot box and goes up along the bend. This location actually moves the fuel line far enough from the exhaust manifold and the associated heat.

The evap line ends into some control valve. I did not want to expose the evap system unnecessarily and chose to hide it here.


It's actually right by the bottom of the passenger foot box, near the 4" frame tubing. Here you can see the fuel supply line come up too. The location for this purge valve looked good. I used some nutserts to mount the valve to the sheet aluminum.

From here on things went a bit sour. Too start, the picture above does not show starter motor. Once the starter motor was in placed the purge valve was awfully close to it. I haven't looked into that problem yet. My attention was concentrated on the fuel leak that was happening at the only custom made flare between the hard line and the hose that links to the engine.


My attempt to repair the flare only ruined the line further. The above pic clearly shows how the flaring tool slipped stripping the top level of metal. This resulted in a purchase of a 30" fuel line with the flares done on both ends at the factory. The new line was a bit too long. I would love to have something around 24-26".


The new line above is a bit long and had to curve to the front a bit. The tissue on the junctions is there to see if there are any new leaks. And there were sadly. I was not out of the woods yet. This time I could only blame the barb fitting. I was using the Factory Five supplied Edelmann fitting. Till now I have two theories, either the fitting was defective or it was damaged during my first installation against my hand made flare. I found it a bit challenging to find the fitting. I could easily order it form Summit racing but the shipping would cost me dearly. Luckly, I found out that WrenchMonkey had the fitting and would not cost me too too much for shipping. They are actually located very close and were able to deliver my part next business day. Once the fitting was replaced I was back on track with no more fuel leaks. However, all these fuel leaks had ruined my black rubber coating on the foot box. I'll have to fix that up one day. On the bright side, nothing caught fire. I have a video of the car cranking with fuel dripping and sparks flying but that's material for next posts. For now, I have bought one of these
