Help me pick components for E85.
Help me pick components for E85. First off, my friend is welding in the rollbar and mini-tub kit this winter, so the fuel tank will have to come out. I figure it would be a good time to upgrade the fuel system to handle anything that I might want to throw at it. So, I want a fuel system that will easily handle an NA resleeved LS2 454. I'm not doing anything with the fuel rail or injectors yet, since I don't need to (correct me if I am wrong), and that is easily upgraded down the road. I am going with a Walbro 450 or 400. I have Mechman 370 alternator, so I can handle extra current draw.
I am assuming that I will need a pump, new lines, and an adjustable regulator. So, here is the plan. I will update the list as more information comes along.
Pump: CHRS1313 Dual Walbro 450 with plug and play kit.
Regulator: Holley 12-846
Filter: MagnaFuel 7010 25 micron stainless
Lines: -8 AN PTFE poly or kevlar braided feed and return. Fully assembled, I'm not trying to build them.

I am assuming that I will need a pump, new lines, and an adjustable regulator. So:
- Will the stock filter work? the filter info or info for aftermarket filters that cross reference should tell you if its ethanol friendly or not. most modern cars factory filters are ethanol suitable
- What is a good adjustable regulator? any quality non china brand. aeromotive, magna fuel, fuel labs etc
- What size fuel line do I need? 3/8" right? being NA you could likely use your factory OEM supply steel tube as the return and for N/A single -8 feed would be overkill
- What adapters do I get for the new fuel lines to connect to the tank and the filter (I know that the adapters at the regulator will depend on the regulator's connections)? 3/8" to -6AN seems to be pretty common.

My question about the filter is more in reference to the input and output sizes. I know that I need to verify that they are ethanol friendly.
Since the factory fuel line is 3/8", I assume that the filter and the bucket output are both 3/8?
So far, here is what I am thinking:
Pump - Walbro F90000267 (genuine Walbro, not a knockoff)
Regulator - Holley 12-846
Filter - Fuelab 848 with 6 Micron / Fiberglass element
-8 AN PTFE poly or kevlar braided feed line
-6 AN PTFE poly or kevlar braided return line (or just use the stock fuel line)

ideally you want the same size inlet and outlet as your supply line, with a filter that will not retard the flow too much. there are heaps of suitable aftermarket filters that will provide -6, -8, -10, -12 ports with a relative flow rate.
genuine walbros are great pumps and I haven't seen E85 kill one yet. the reg and filter you've suggested are both quality and suitable for your application.
-8 feed -6 return is plenty big enough for your application. just be aware some of the cheaper brand fittings are sold as -6, -8, -10 etc but have a significantly smaller internal diameter compared with the "brand" name fittings. for your application I don't think that will matter as -8 feed is overkill.
if you do a fuel system you're better off over doing it than doing it just to standard. provided your hoses are big enough to flow and your FRP isn't overflowed from too much pump then bigger to a degree is better.
a speedflow or aeroflow dealer catalogue will have all the fittings and adapters you need as well as hose and the relative part numbers

However, what is the size of the feed output from the stock fuel pump housing? Everything I have been able to find online just has pictures, and they look to be the same as the push-on connector on the stock filter, so I think it is 3/8". Might be no point in going -8 unless I get a whole new fuel pump assembly that has -8 or -10 connectors.
Thanks for the info on connectors. I will most likely be getting fully assembled lines, so I will keep that in mind.

I wonder if Squash Performance offers their kit with just one pump. That would be a perfect option for -8 feed, -6 return, and stock evap.
What is the difference in AN and ORB fittings?

So, Squash Performance does have a single pump kit, but the price of their plug and play kit makes the CHRS1313 dual setup and plug and play kit just about the same price. Is there any downside to running dual 450s, other than current draw?

Verdad Gallardo I plan on the regulator being in the engine bay. I won't create more heat than the motor, right?
I use an extremely knowledgeable tuner, and I will be using an adjustable regulator. Would those two things negate the issues?
I am going with -8AN feed and return connections, so I will have -8AN feed and return lines.
