custom modified fuel rail

as some of you guys know, i tend to get things done on my own and luckily i've got one of the best fabricators in my own back yard. i'm tired of worrying about #8 and watching it (along with the rest of the left bank of cylinders) showing signs of going lean so i had chris at floored fab work his magic in between his other projects. simple fix but it should be effective...

the biggest concern is the low pressure spot near the rail inlet so moving the inlet away from any one cylinder was a priority for me, and moving it to the center with a "y" inlet should better insure equal pressure to both banks. we just felt this was a better solution.

Can you explain the benefits of your modified fuel rail design? Or, how is it better then the OEM?

Mine is not looped, I have due 8ANl inlets and a single 8AN return. The stock system is returnless and felt this was draw back in a All out set up. By no means should everyone do like me, TTM's setup works well and adress the issue in a less complex way.

I hope you don't plan on cooking those fuel rails. They are not edible.

Who made your rail for you Sneaky, dont you like the return style fuel system? Did you change out your fuel pump too during the build?

I need also to modify my rail in not expensive way. Can you guys explain why both of you have the ends with threads?

Both of you have two inputs for fuel at the beginning of the rail, one Mikey did the Y shape and Sneaky just did new in put in the middle close to the pressure regulator.

Please some help guys, what parts you used?

i can't comment on sneaky's but if you'll notice in my second pic, i removed the original inlet so mine is a single "y" inlet. also, the threaded end is not modified...it's just the stock fitting for a pressure gauge.

the only things you'll need if you want to do this are some an fittings, some fuel line, and the ability to weld.

VERY nice stuff bro. Great solution to a potential problem area. I've seen too many M113's go byebye becuase of #8.

Ok dumb question, but why does #8 get low fuel pressure when the inlet is right there close to it?
