Fuel system time

Heres my plan:
Fuel Lab 41401 Pump

http://thmb.inkfrog.com/thumbn/importblowoutsales/41401-2-large.jpg=500

2 Racor Fuel Filters/water Seperators of Different Microns (what microns?)

Stainless braid lines and Russel Connectors where possible.

Areomotive 13109 Regulator w/ Guage
http://www.aeromotiveinc.com/prod_imgs/img-10-1-large.jpg

Sounds good?

Also

For the Y piece that splits the fuel lines to goto the head. What Do you guys use? Theres plently of metal T's But is there something in the shape of a "Y"? And what Fittings screw into the head?

Get a hold of Dave at DI about his head fittings. The Y block I used a "Earls performance" block. Dont use one of their Aeromotive mechanical gauges.... mine screwed up on my 3000 mile trip and almost cost me the trip.

And if you use that pump you may need to modify your lines as I dont think the stock lines are going to feed that pump very well. Maybe someone who knows more about that will chime in. I would go to your local Parker store. They can help you with any fittings and lines you need. They got to know me by name by the time my system got done.

What you want is already on my truck, lol.

There are some pics in my webshots and hopefully soon I will start a thread about my system.

So modify the Tank to Pump lines???

I would Like to run a Fuel Pressure guage in cab.

Might have to add a larger pickup tube and install new larger lines from the tank pickup to pump, then from pump to heads heads to tank.... I know you need them for the comp setups, but not where the line is drawn. That pump flows alot.

-Matt

Im in the process of building my fuel system also. Im going to be using a fuel tank sump instead of a pickup tube. My filters are 25 micron pre pump, 2 micron post pump. I ordered most of my fittings online from Jegs and Summit Racing. No one around here seems to carry AN fittings in stock. Im replacing all the fuel lines including the return w/ -6an size lines.

Yes, to use a pump the size of a fuelab you'll need at least 5/8" to the pump inlet, and 1/2" out from there. Those are the minimum size lines Fuelab says are needed for the pump.

You'll be replacing all the lines in the truck to run a fuel system this big, with the kind of flow to the engine and returning to the tank when you're not at WOT, you can't use stock lines.

Or you can run the stock setup from the tanks to the switching valve, and run new line from there up and use a Bosch 044 or the other SD look-alike pump(can't remember the name).

Oh yeah, it isn't going to be cheap, I've got 1500 in mine, plus or minus 100, prolly plus 100. :D

:whs:

I havnt tallied up my setup yet, but I would not be surprised if it was VERY similar. All those little fittings and pieces of hose add up quick. However you can shave off a few hundred if you dont use SS up in the valley like Dave and I did.

If you dont like the idea of spending that alot of guys here use setups that dont require so many money consuming modifications.


-Matt

I did the Walbro style pump and filters and love them. It was based off of TomS fuel system. I did Aeromotive SS line and fittings at the engine and spent way less than 1500 on mine. I think i was around 500 for my whole project.

My pump alone was 350. LOL And there is not a single piece of my system that wasn't replaced, including the tank. Front to rear, entirely new, lol.

I wanted to do a Walbro or Bosch pump, but it wouldn't have gotten the job done. If I do a fuel system on my other OBS it will for sure be getting a budget system, and yes it will be plenty under 500, already got it spec'ed out. :D

Dave

Is there any downside to running a -10 pickup, -8 feed, -6 an to heads and a stock return side with a walboro pump? It flows pretty close to the fuel lab at 14V...

that is my current setup..

Your Walbro flows close to a Fuelab? Have any links to info on that by chance? :confused:

I would consider using the stock feed as the return if that is the case, but there is not alot of difference between a 5/16 and 3/8 line.

Pull the return off underneath and see what the return pressure looks like going into a bucket.

Dave

tom S had a flow chart in his for sale ad...let me see if i can find it.

And as far as flow, i'm going off the 70 GPH that dennis sets his to...i know they are capable of more but...

New sealed Walbro 392 and install kit - Powerstroke Nation (http://powerstrokenation.com/forums/showthread.php?t=32802)

about 70 GPH @ 14 V @ 60 psi.

Dave

I didn't touch any lines except the ones at the engine, but it wouldn't be that big of a deal if I had to. I need to get a gauge in cab and see if my fuel psi moves when under WOT. I am betting it doesn't move much............or at least I hope not!LOL:doh:

I thought the reason for going to a Fuelab pump is to get rid of the brushless motor and the fact that you don't have to run them at full potential the time? I am impressed with my Walbro pump to say the least. It has been on for about a year and a half with no issues other than the fact that my relay crapped on me.

Yes it is, much easier on the pump.

I just looked on Fuelab's site and 70% speed is ~82GPH @60psi @13.5 volts for my pump. Not that it really matters, because that's more than we'll need.

I built my system for competition, I have 275's right now and may go bigger, so I wanted to do it one time. I hate having to re-do stuff. :D

Dave

DO you think the fuel Lab pump is over kill for 230's??? I like the fact that there brush less.

I don't think so.

I don't think so. Better to have overkill than to be pushing the limit.

Dave

At what size injector do I need to start worrying about my fuel system? I'm running II's now and I'm not worried about them but I want to go to ~250cc hybrids, maybe this winter. Thanks

Only way to know if you're OK right now is to put a gauge on it and go run it, watching to see if and how bad the fuel pressure drops.

I would do at minimum an electric pump and filters underneath with 250's, and that may be barely enough.

IMO, the SD style pumps can flow enough for injectors smaller than 250's if they have a better pickup than the stocker, and bigger lines up to the engine.

Dave

I did a 1/2" pickup with a 1/2" feed to a 12 micron pre filter head. from there I used 3/8" to and from each oem sd pump to the 2 micron post filter head. from there a 1/2" feed up to the y spliter in the valley of the engine. from the y spliter 3/8" to the rear of each head with 3/8" out the front of each head to the regulator. then 3/8" return to the tank.

with this setup I have had absolutely no fuel delievery issues.
I can't get the pics to load the file is to big and i'm no computer wizzard.

That sounds like a fairly good cost-effective solution.

Do you have a larger picture??

my 'eye' dont work on ths key board at ths school m at n houston today. ll try to post one up for you as soon as eye can.

I did a racor 10 micron filter/water sep. before the pumps, then from there pumps are Bosch in S/D holders After the pumps I ran -6 to a tee then 1/8 to -6 fittings in the back of the heads. Used 1/8 to -4 for returns to the aeromotive regulator.Then returned thru the stock lines.

Im all ears

whats the benefit from changing to the elect. setup?

More constant fuel pressure...(in my opinion) better fuel filtration...eliminate the factory filter bowl...clean up the engine valley, smoother and more quiet engine...the list goes on and on...

:whs: ALOT quieter running engine, sounds smoother too versus my other truck with stock junk.

:rockwoot:o ok

Question for the Y part fuel splitter.

What size should I go. I pan on using 6an for the start, But for the 2 other ends (heads) what size? 6an? 4an?

I Plan on using these nitrous pluming fittings.

Are you still gunna use the fuelab pump? If so why are you doing 3/8 supply line?

As for your question its up to you. There are different ways to feed to fuel to the heads. The rear supply that the stock system uses is 1/8 pipe into the heads, which you can get adapted for use with either -4 or -6 line. Or you could install some DI high flow fittings right into the fuel gallies from the rear of the head (between head and firewall) that are -6.

For my Y fitting I used a Earl's Performance Plumbing y block. It looks good and you can install whatever size fittings you need into it and it has holes to mount. Just an idea.

Yeah im planning on the fuel lab. or 2 sd's. but probaly the fuel lab... I plan running the feed lines to the back of the heads.

I like the sound of those DI high flow fittings.

Would -8an feed then split to 6an lines be better?

or would even 1 sd pump be enough to keep up with 238 hybrids?

Im not sure if my nozzles are upgraded on them... there .0085".

If your going fuelab your not doing it to go small. A -8 supply to -6 feed lines would be a better option. I did that and fed them into Davids fittings, works great.

I went with a -8 return but I dont think you need it that big if you dont want.


Just curious. How are you modding your tanks for pre pump flow?

Well 1 tank is brand new, the other leaks... havent used it for 2 years and Im thinking of replacing it with a bronco tank... If im doing that Ill probaly Mod that tank some how, and use that one mainly, and keep the other tank for a reserve tank

This is what im using. Actually im making mine. Its a Fuel Sump that mounts at the bottom of your tank. Get em from Hellmann Performance for $175 I think.

What did you guys do for the return line??

I used a 1/2 line that went back to the tank thru a bulkhead fitting.

I got all my fittings and the pipe from the parker store. Had to borrow a tubing bender from work to bend those tho.

If you need I have a few more pictures in the thread I started a few weeks ago about my engine and fuel system build.

Good Luck, hope it works out.
