FFE PRIMARY RAIL FITMENT UPDATE

Ok. Pictures will have to wait until the next couple of days since my camera decided to go screwy on me, but here is the news a few of us have been waiting for.

The current primary rail DOES work on a 13B-RE. After talking to Aaron, I was the new guinea pig for verifying the fitment. I am currently running a stock secondary rail, so I bought the appropriate -6 O-ring to -6 fittings and two -6 to 90* barb fittings to allow me to connect everything.

At first, I pulled my diffusers out and cut off the lower section, intending to just use the upper half as a spacer. Then I simply swapped the lower O-rings on my Bosch injectors for the Denso cushons and installed the rail. When I fired the car up, I had a high idle that hadn't been there before. I pulled everything apart and also pulled my diffusers out to check them as well. It turns out that the grommets on the diffusers weren't in the best shape, and I guess that pulling them out in the first place made them worse.

Not wanting to have to source new grommets, I decided instead to put one extra Denso cushion in each primary injector port to take up the space left by leaving the diffuser out. I reassembled everything and tried again. SUCCESS! No leaks (fuel or vacuum) to be found. I'm pretty certain that leaving your diffuser in and using just the one cushion will work fine, but I would check the grommet while you have everything apart.

Cliff's Notes: The FFE primary rail DOES work on the 13B-RE.

Many thanks to Aaron for being prompt with getting the rail to me overnight as requested as well as having great customer service. Definitely continue to support a great vendor making incredible products!
