Ok, time to get rid of the stock rails, lines, and filter. It's severely restricting fuel flow.

I'm planning to do -8 feed and return. I plan to use the ebay truck fuel rails.

Is the Aeromotive A1000 regulator the one most people are using? A1000 Injected Bypass Regulator - Aeromotive

What's a good fuel filter that's E85 compatible?

What's the real word on crossing fuel from one rail to the other versus wying off the feed into both rails? The former should be okay under 1000 rwhp, right?

 

I used the holley rails and made custom brackets. Check out my build thread. There are some good pictures in there of them.

I would do a 10an feed and 8an return.

 

Michael, what are you planning on doing with the truck? If you are keeping it, are you going to try for 1000rwhp and a 9 second slip?

If that is your goals, I would probably also do -10 feed and run e85. If you are going to build a fuel system, might as well build it overkill once. When I was on E85, my plan was to run a -10 feed, wyed to dual -8's into the back of the rails, then -8 out of the rails to the regulator. Are you planning on a fuel cell or stock tank?

 

I have done my lines four different ways. From my experience keep the number of fittings to a minimum. Try to use as little 90*s as possible. Also try to use hose/tube bends not the drilled hard angle fittings.

I have used a couple of different filters. I am using the big fuelab one now, i like the internal design of it. My suggestion on which filter to buy comes down to replacement filter availability. Also make sure replacement orings are available or provided with the filter.

One last tip, buy a hose end tester and pressure test the lines prior to intall.



Ebay rails? Do you mean the professional products ones?

 

I'm just going for a 10 second run, but I want the reserve to turn the wick up to 20+ psi. Nothing is changing inside the fuel tank. It's just a stock tank with dual Walbro 450s. The stock fuel regulator cannot handle the 450. When I get off the gas the AFR goes into the 11s. Hell, doing the burnout at the strip I think my AFR was in the upper 9s or low 10s because both 450s were on at that point (in boost).

 

No, not professional products. Just go to ebay and type in "silverado fuel rails".

 

I searched for that. One set looks really nice. It had pictures mounted on the truck intake. The rails were black. Is that the set your gonna buy?

 

yes, that's the one. Looks to be a true bolt on kit and also comes with the crossover braided hose. That's what I was asking if it's acceptable to do the crossover like that. I've read on here that crossing over from rail to rail is fine if under 1k rwhp.

 

Yeah that kit looks nice and bolt on too.

I have done both. Currently I have the crossover method. Atomic uses the crossover method. He is at 1k.

 

Anyone have an estimate of how many feet of AN hose I will need for the feed and return for an extended cab?

Also, what's the best way to clean the lines out after I assemble them? I'm planning to use the Summit AN hose, same as what I have for the tranny lines.
