Phase one - manifold fuel rail modification completed.

Props for Franco for all the help!!

 

Looks nice and clean!

 

sooo.. what did you do to the fuel rail? I don't catch on to subtle changes well.

 

before on the stock fuel rail it's entirely made of hardline from the right to left side of the fuel rail.
Hard line connects both side under the manifold.
I cut of a small section on the left and right side and replace with flex fuel line for easier access to pull the fuel rail up when unbolted.
Before (Picture from scoobymod) but bascially the same thing

 

yeah, I think only the people who have actually messed around with their motors actually know what you did at first glance. That looks like a good idea, I know I have a hell of a time trying to take out the intake manifold without bending any of the hard lines. I think I'll do this mod when I go to put it back in. Thanks for the idea....

 

i've messed around with motors, but not with these new-fangled motors post 1971. hahahaha

Even if I did, i still don't catch on to changes well. My dad changed carb needles on his 240Z and i didn't even realize they were "speed-shop" needles until I drove it.


as for the hard-lines, i think subaru did it for safety reasons since they are carrying fuel over surfaces that are pretty hot. The idea is good for ease of installation/removal, but on the other hand, you should periodically inspect those rubber hoses to make sure that they aren't deteriorating. Hate to have a fuel leak over a hot engine.

 

manifoldddddddd

 

looking at the overall fuel lines, I would say stock its roughly 70% hard lines, 30% rubber hoses. What we did was change the ratio to now 50/50.

I don't think heat should be a problem since this is not a race car, its a street car.

 

i made everything with enough slack so i don't think it should bind to anything or touch the hot surfaces.

 

vapor lock?

i havent heard of a new car getting that

 

true true. I still say inspect the lines once in a while tho to make sure they aren't cracking.

 

you should see Eddie's Pot exhaust heat shield

 

why not upgrade the rubber to stainless?

 

Eddie is Taiwanese how much are stainless lines and fittings

 

yes i'm cheap. earl fitting cost too much
