I was wondering if I can make my own kit and how to make this kit. I already have a 4 gallon fuel cell that I can literally mount in the trunk area. I also have a msd boost a pump, so I can use that to flow the nitrous to the engine bay. But I have no idea how to run the lines and/or if I can even do this correctly with the parts I have. All of the ports on the fuel cell are -8, but how do I keep that as a direct fuel line to the engine bay. Any help is greatly appreciated.

This is the fuel cell I have....

Please help, can this be done?
Thanks,Tom

edit: This is a lt1 car and still using its factory fuel rail pressure if that matters?

I suspect you want to run a nitrous kit with race gas in the stand alone??
If that is the case you will have to mount another fuel pump and regulator somewhere. Run the fuel line under the car up to the nitrous kit fuel solonoid.. If you are not running race fuel pr a huge nitrous kit, it is kinda a waste of time. You can upgrade your factory fuel pump to handle it.

Does the fuel pump have to be a high PSI fuel injection pump or can you use a carb pump like a holley black? Im thinkin about pieceing together my own stand alone also...

Yes I have the msd boost a pump laying around that I can tie into the fuel side to make the stand alone kit work. I also have a racetronix pump in my tank, But id rather run race gas in my stand alone and run seperate kit for this. This pump I have is high pressure, I believe its a 255 pump as well. Will that work I believe it will and if I run a regulator I can bring the pressure down to 5-6 psi to the solenoid or NOT?

First of all if you put a fuel cell in the trunk, you will be legally required to use a rear bulkhead like this one from Wolfe: http://www.wolferacecraft.com/detail.aspx?ID=783.

A boost-a- pump is designed to assist an existing pump. Not as a primary pump.

If your making a stand alone system you can go with either a low pressure or high pressure pump. I have a 1 gal cell mounted up front in my car but I had to do a little trimming. A low pressure system and a holley 803 regulator is what I'm using. I would personally want at least a holley black pump. The problem with a high pressure stand alone is the larger bypass regulators take a little longer for the pressure to stabilize after the solenoid opens. I don't think you need that big of a fuel cell.

There are plenty of options to do this yourself if you are capable. If not make it easy on your self and buy a pre-made kit from Harris Speedworks.

Now if you want to build it yourself, are you gonna run it on low or high pressure? Id also go to a 1 gallon cell or so if you are just using it for the nitrous.

What would you guys suggest? high or low pressure system? I'm new to nitrious so dont know which one i would need...

As for being in the trunk I dont mind and to have the hatch cover thats cool with me too. But why wouldnt that pump work although it can be used to pull fuel from the cell and carry it to the front, cant it? Is it better to have a low pressure system or a hight pressure system? I thought carbs were low pressure?

The advantages I have heard with a low pressure system are:

1. There are a lot more nitrous people who use low pressure systems so more people will be able to help you with a tune.

2. You can use bigger fuel jets and they are less likely to get clogged.

So if i were to do a low pressure system on my fuel injected 5.3 swapped s10, i could use a holley black pump with a holley regulator and a small one gallon cell under the hood? That set up pieced together plus some fittings and lines of course would be way cheaper than the HSW stand alone kit... Looking to stay on a budget here...

Low pressure... with a fogger it's the only way. High pressure with a fogger the jets will be so small they'll clog constantly.

I'd put a smaller cell in too.... that way the fuel that's in there will be fresher. 4 gallon will be so much for a standalone that you'll end up filling it up, not having to add any for a long time... long enough so that with a street car unless you're out runnign 10 to 15 races a weekend you'll have issues with the race fuel going bad from being in the tank so long.

You need the bulkhead also like mentioned, another reason to put a small cell under the hood so you don't have to deal with that. Alot shorter fuel and return line too.

Is a stand alone worth it if your not going to run race gas?

JL ws-6

iTrader: (50)

Yes, it will give you the ability to tune your fuel pressure for your nitrous systems seperately from the EFI, and it also allows you to run low pressure, which will help alot with a directport system. Jet sizes due to the fuel being a lower pressure will help prevent clogged jets.

Low psi you will run a 4 to 6 jet spread, with say 5.5 to 6.5 psi of fuel pressure, a high pressure you'd have to run a 12 jet spread or more, so a 30 nitrous jet (which is a good sized hit, about 275 worth give or take) would need a really small fuel jet... which would be very prone to clogging, and that would give you a really good recipe for disaster.

Is it not true if your nitrous system is high pressured you want to match your standalone accordingly as high pressured?

JL ws-6

iTrader: (50)

Nope. Nitrous will be running 950 to 110 psi depending on what you want to run it at, fuel needs to be low enough so a decent sized jet is usable, to prevent clogging as I stated earlier.

I don't think anyone's gonna try to run 1100 psi of fuel pressure LOL, what jet spread would that take, like a .028 nitrous .007 fuel That would clog about instantly.

(sorry) So let me ask you this say if a person has a high pressured nitrous system from NitroDave and wants a standalone. Then has his eye on a low pressured standalone system such as the one that Cold fusion offers. Cold fusion tells the guy that if he gets their standalone which is offered only in low pressured they would give him low pressured jets for free. Lastly the shop that this guy deals with tells him they can build him a high pressured standalone for a decent price. What do you think about this situation? Thanks

I believe the plates for these cars work on high or low with the associated fuel jet. You would need to talk to dave or hsw to make sure.

as far as low or high pressure standalones the only difference is the pump and regulator.

JL ws-6

Suck it up and relocate the battery. No reason not to do that, the weight in the back of the car will help it leave better.

Only other option is the harris setup that shifts the fuse boxes around, unless you go with a burkhart type bumper support and mount a 1 gallon up in the nose of the car, ditch the washer bottle and all that nonsense that's up in the nose. That would work too.

we also have a dedicated that does not require anything to be relocated...including the fuse box in most applications.
