I have hit a snag on my blower upgrade. How i once had my fuel line crossing between rails no longer fits due to the increased length of the blower. System is return with the section in question being -8 AN fittings. Images attached to help clarify.

Going from a 2.3 Whipple to a 2.9 Whipple. Line crossed with 2 -90° fittings and hose below the front of the housing before. Now they don't reach the rails on the driver side due to length increase(see images) the On3 coolant crossover delete fitting were barely clearing before but with the change in space they will surely not clear if I have to extend the connections. How are other routing this fuel line? Pictures and suggestions welcome.

I ran a 45 degree fitting and went along the coolant crossover pipe for a short span and then went back. Did this on both a 2.8L and a 3.6L with like a 8" line.

That's what i had before. I think the crossover delete takes up more space. It's a small problem causing me a big headache.

looks to me like the 90* fittings need to be further in front of the blower. basically a flexible exstension could come off the fuel rails. might also be able to get rid of the 90* fittings and just use a longer hose with two female AN fittings on it.

or (and i know you won't do this) route the fuel crossover over the top of the blower

or (not a great idea) use 180* fittings to route the crossover around the back of the blower.

those are my ideas from here. i usually have better solutions when i can put my hands on the problem.

Thanks for the feedback. I considered both going over the blower and the 180° fittings. Like you, I don't like either option and actually going over doesn't work because of overhead clearance. I'm trying an angled fitting but I'm not sure the clearance will be there. We shall see.

When you ran the 45 degree did you go towards the blower or away. The only way I could get it to work was the 45 had to go away from the blower and then loop back. Added an extra few inches but it worked. In the pictures it always looks like you are going towards the blower instead of away. I will find some pics.

I actually miquoted. I was running 90° fittings at the time, not 45°. I am looking at adding 45° fitting this time to see if that works.

Like I said I had to point them about 20 degrees away from blower then wrap back around to the other side. If I pointed straight up or towards the blower it would hit the coolant crossover.

*Edit* to add pics. The stainless braided is my fuel crossover.

I see what your saying. What size line is that? That could be an option if this first attempt doesn't work.
