My dilemma is that I have an AE86 Corolla which is in the final phases of installing a new (and much more potent) 4A-GE. I am running aftermarket management and individual throttles, so most of the stock plumbing and wiring is long since gone.
I am running out of room on the intake side of the engine bay and the stock fuel filter sits right on top of the end of the fuel supply line from the back of the car. The filter is right where my plenum needs to go. The stock flex line is also too short to reach around the quad throttles. I have already tweaked and extended lines to successfully relocate the charcoal canister, but the supply line will be seeing higher pressures. My thought was to remove the stock filter, cut off the upward bend in the line, and re-flare the hard line to take a new fitting. I will use custom flex line from the hard line to the fuel rail and fit a filter inline somewhere where I have room. Basically I will end up with two flex lines, one from the modified hard line to the filter, and a second one from the filter up to the rail.
Here's the engine in place, trumpets fitted, and the charcoal canister and filter aren't giving me much room.
Here's after the canister relocation, doing a plenum mockup, not the final design obviously, but just a representation of the dimensions and space required.
Here is also post canister relocation with the filter no longer tied to the inner fender and bent a little bit out of the way, but now the flex line really doesn't fit!
View from above looking at the space I have available. I would plan on cutting the line after the bends, say just below the lower bolt sticking out of the inner fender.
I haven't done this type of procedure before, but I am reasonably skilled and generally careful.
What is there to know besides don't waste my money on a cheap flaring tool? Am I foolish to go with a 37-degree flare, and use AN for everything custom, and then just one adapter fitting back to the metric thread on the fuel rail? The hard line is 8mm, FWIW. I would also check carefully for leaks, and I have room to play with, so I could probably try again once or twice. I also have a second set of stock lines if it comes down to it. I am guessing that the stock setup uses a 45 degree double flare with some sort of metric threads on the fitting, but I haven't measured to be sure. Should I just pay someone to do it? Am I screwed before I start and should go back to the tank and bend a new line?
