I'm turning 40. My mid life crisis is here. I have my ls414..I wanna go procharger and e85. Car is a gbody 1978. Can someone point me in the direction for a fuel system? What is needed? Pumps? Lines? New tank? I've searched but kinda confused. Flex fuel?? Thx in advance.

Are you wanting to do the fuel setup yourself, or just buy a kit? As you are probably already aware, e85 takes a lot of fuel volume. I would recommend to start out in the right direction, and look into running either twin Walbro 450s, or a large external pump like a Magnafuel. Might want to get in contact with Nasty Performance. They could probably set you up nice.

What procharger are you going after? How much power do you want? Big difference between a mid level D1SC setup (600-700rwhp) and say a F1X setup which is north of 1100hp easy.

Thanks for repling guys. Im shooting for 750 to the wheels. The car is a driver, but im not apposed to a completely new fuel system. I just don't know how to run it. 2 pumps? 1 pump? D1sc is the blower. I want whats best for the motor. But its not a race car at all. THanks again

Well, E85 needs a lot more fuel than gas does to make the same power... granted, you can make more power with e85 thanks to being able to add more timing due to it's extra octane effect.

So you will need at least a set of pumps, larger than the walbro 255s I have, since they won't be enough for your targeted power level on e85. I'd run a hobbs switch on one of them, and you will need to make sure the pumps, lines, and injectors are all e85 compatible.

Thanks for replying. How about my 36yo gas tank? Use 2 separate gas lines to a regulator? #6 or #8? I'm totally green to this. I don't mind cutting up the tank, but I don't want a fuel cell. I was reading to use stainless metal lines. I guess it's too corrosive ? Thx again

Also, what is the top of the line fuel pumps? I can get a new tank for my car that has number 6 or 8 outlets. Just kinda confused

Your best bet is have Lonnie's, or nasty set you up with a complete kit. I can tell you from experience go way overboard with what you get because at some point your going to want more power than that d1 can make and you'll have to do it again. If your going e85 go -8/-10 lines, twin 465lph pumps or a big external, Hobbs switch, boost reference regulator, big filter, and a nice wiring kit.

Thanks bro! I'll get ahold of them.

I agree, I always send people to Lonnie's for the fuel system, and I recommend the PTFE/teflon line upgrade. Bob

You can get the Walbro 450lph E85 pump kits off Amazon for about $100 each. Racetronix offers very nice drop-in pump hanger assemblies and dual pump parts for G-bodies. Get submersible fuel line from Gates. As well you are going to need either a dual hotwire kit or a Boost-A-Pump to ensure the correct voltage gets out back to the pump.

Buy a new tank from Rockauto or the like. Chances are good that old tank is full of crap you don't want going through the fuel system.

I'd run a -10AN feed and -6 return line; Teflon-lined is a good measure. But, ethanol isn't methanol.

You are also going to need good injectors - 100+lb/hr.

As for the blower that is up to you. I'd go for at least a D1SC.

thanks mike...do you think I need a grand national tank? different baffles? I think im gonna go with a f1a super charger. I would rather have more than enough. I also like racetronix stuff too.

It's funny how quickly things grow and escalate. You started at wanting around 700, and now you're going F1A. I'd go bigger than you think on the fuel system because that F1A may end up growing into something even bigger down the road.

When I first ventured into forced induction, I got a D1SC, and Lonnies twin in tank 255 kit. I figured making 700-800 would be all I'd ever make. Well, I'm now at the limits of the twin 255s with an F1A feeding a 416ci motor, and making close to 900 at the wheel without even spinning the f1a to it's max.

The GN tank won't fit a Malibu without modifications to at least the filler neck. But, you should check to see if the TBI tank from an 86/87/88 Monte Carlo works - it is internally baffled. My recommendation would be those new socks from Holley, or building a bucket that fits into the tank. Of course the extreme would be cutting open the new tank and welding in baffles. Personally, I just keep at least a 1/2 tank of fuel at all times to deal with slosh/starvation.

Also, you will need a boost referenced adjustable fuel pressure regulator for a return style system; and should consider a fuel composition (flex fuel) sensor to compensate for any odd blends of fuel.

Thanks again guys. I will bit the bullet on the procharger HOPEFULLY next week.

Dual 450s will not fit in a MonteCarlo EFI tank. I'm running dual 340s from Lonnies and had to slightly notch the opening to get them through. Rickstanks.com has a GBody stainless steel tank (part# 032510) that comes with dual 450s. It won't be cheap thou. I may make the switch to E85 over the winter.

This is going to be a good running G Body. Bob

Thanks Bob. Little by little. I have the fuel system almost bought. Driveshaft today. Gonna swap the clutch soon. Then add the procharger. That's the biggest $$ item. Hopefully in a month. I'll get it from you. Thx
