Initially, I was only going to upgrade the secondary injectors and retain the stock primaries. Planning out the fuel system required a good deal of thought and effort, and I eventually succumbed to upgrading the primaries as well. Namely, it didn’t feel right mixing new and 2-decade old technologies together. <\/p>\n

I went with Full Function Engineering<\/a> CNC’d and anodized rails with flow-matched Injector Dynamics 2000’s for the secondaries and Injector Dynamics 725’s for the primaries. This set up should be able to support past 500HP, although I won’t be pushing anywhere close to that. I was eventually able to amass this collection of goodies: <\/p>\n

I bought more push lock fittings than necessary to have spares, and it’s a good thing I did, because 3 of them were sacrificed in the process of the install. I first measured out and cut the lengths out of a Fragola 8000 hose, but when I tried to push on the fittings, it just wasn’t happening. The tolerances between the Fragola hose and the Red Horse Performance fittings I had were slightly off, and that was enough to make it impossible. So I switched over to an Earl’s Super Stock fuel hose, and that was a good match – but still by no means easy. <\/p>\n

I wasted enough effort with the first setup and it was getting late by the time I finally got one fitting installed. So the next morning, I decided to enlist the help of someone I thought would be better suited for the job. I wanted to hedge against uncertainty and make sure all the fittings would be pushed on all the way, there were no more second tries – supplies were dwindling. By the design of the push lock barbs, if you stop pushing while half-way on, it becomes very difficult to fully seat the hose.<\/p>\n

To help further guarantee a successful outcome, I took all possible preparations: the fittings were left in the freezer to contract the metal, the barbs were lubricated with oil, and the hose was boiled in water to expand the rubber. Mr. Freshlove<\/a> (check out his blog) made the job look like easy money. <\/p>\n

Fuel lines complete. I used Oetiker stainless clamps over the barbs as added security. <\/p>\n

Here’s a look at the fuel rails installed on the car. Impeccable machine work, everything fit together flawlessly. <\/p>\n

And with the lines plumbed. <\/p>\n

I’m maintaining the stock Series routing, but I chose to feed the secondary rail first to help with the transition to the big 2000cc injectors. The factory setup feeds the primary first and then the secondary. I didn’t feel that it was necessary to add in clutter and run a Parallel setup (where both the secondary and primary rails are fed simultaneously via a Y-block). <\/p>\n

I’ll need to finish it off by hooking up the Fuel Pressure Regulator, but I will get to that when the UIM goes back on.<\/p>\n","protected":false},"excerpt":{"rendered":"
