Mine either. The braided lines are connected to the tank hoses , inside the wheel well. I tried to keep the fuel lines away from any heat source or and from the pulleys.

I am doing just this. I've used two front 94 cast deville exhaust manifold to route the piping under the engine. I don't like the look of the over the trans crossover pipe and think it will clean up the engine bay quite abit. It is difficult but doable. Not sure how it will hold up over the long haul. I'll be posting pics soon, almost done with the exhaust!

Not that difficult - that is the way I ran mine. Front pipe ran in the stock location and joined the rear manifold near the right rear side of the engine bay with a custom y-pipe and out to a bottle muffler (was going to use a Flowmaster 80 Single in dual out - but got cheap ) into another 'Y' after the muffler to split it out both sides of the car. In hind site, the Flowmaster 80 would have been a better choice.

BTW, the fuel lines on mine were covered along the trunk wall by the heat shield - and yes I still hate them running on top of the engine and adding to the clutter. But if a person was to rework them so that they ran off the engine to the left and down along the transmission that would be the best.

I guess its tough decison to make between a cleaner look or a hot place for locating the fuel lines. With the lines under the heat shield that has to keep them a bit cooler but even with the shield, being next to the exhaust manifold, my trunk wall gets so hot you can hardly touch it. I can understand your approach but a pyrometer test should give the best indication. Maybe I am splitting hairs. None the less your swap is looking outstanding. That's what I call quality fabricating.

You haven't seen cheap till you see my current exhaust system! I'll be posting pics on my install thread soon. I just want to get the car moving. I'll make the REAL exhaust system another time!

I agree.

BTW - just to mention, I ran the fuels line to the left side as the car was oringally a 4 cylinder, so I really avoided most of the exhaust heat...

I just seen an 85 4cyl in the wreckers and noticed the fuel line coming up the driver side of the engine bay to the throttle body. On my 88 4cyl, the fuel lines run up the passenger side from the fuel filter to steel lines on the engine to the throttle body. this is somewhat close to the stock 4cyl exhaust pipe. I believe the fuel filter and return line assembly is the same on 88 4 and 88 6cyl fieros.

Yes, the 88 chassis fuel lines for both engines are pretty much the same.

On all my swaps, I move the filter to the center tank area and then run new hard lines in the engine bay and try to keep any lengths of hose to under 12" and keep the hose as far away from exhaust manifolds as possible.

The fuel lines are kinda hard to see in this picture because they were painted to match. They are steel from the center fuel tank tunnel, and wrap around to the side where they have rubber ends along the passenger frame rail.
