what is the best fuel system to use, i'm currently running around 500bhp on a 044 pump, standard saff fuel tank. iv'e just bought a summit racing fuel cell and another 044 pump. will i need a swirl pot ( the summit racing cell has a small sump built in to it) and another pump. thanks in advance.

 

Im shore mad ad is still on one 044 and normal saff tank with well over 600!

 

Twin 044's are surely a safe bet.

 

Why don't you ask the tuning God lol

Steve

 

Thats what i was going to say Steve LOL

 

trying to get my post count up.

 

that bloody man flue has gone quickly.

 

If its the same fuel cell i got from summit the sump is only good for drag racing, won't help when your hitting a long right hander for a long time, so depends on what you're going to be using the car for.

In my own setup I use a lift pump (Holley) from the fuel cell into a swirl pot, then to 2x 044's.

 

I feel rough as fuck John

 

if you go down the fuel swirl pot route i got a new one in the cosworth parts sale section

 

Yes wes, same as yours. Where did you get your extra foam from for your fuel cell.
Thanks john.

 

agreed

 

I'm defo going to use 2x 044's, looks like I'll need a swirl pot. Just need a lift pump. And some fuel cell foam.

 

why foam, they deteriorate over time too dont to forget, had loads of problems with my RWD built mk5 escort that turned out to be bad foam fucking the fuel up!

baffled medium size non foam tank, facet/holley/ lift pump or STD cossie pump to feed swirl pot, then twin 044/aeromotive 1000`s to filters to 12mm lines (my choice only mind)

done a few big power customers cars aswell as my own like this

 

Best system for what exactly ? And how much is 600+ ?

601 would still be fine on a single 044. 600+400 would not.

Whether you need a swirl pot or not depends on the car's usage, and you say you have a fuel cell. Is the design of this not enough to negate the need for a separate swirl tank ?

Outline your exact requirements and it's easier to plan the build. Then draw each item out on a piece of paper along with flow abilities and requirements of any items.

 

Solid advice there stevie !!!

 

I ordered it from summit at the same time that I got the fuel cell

I'm sure it is readily available over here

 

Has no one tried the new twin setup from ATL, 1 or 2 pumps located in an intank collector, less plumbing on both the feed and return...I made one for the new fuel cell I put in my car, we have to segregate the pumps from the cabin, so it saved making a box for the pumps, I made the collector the diameter and depth of the tank with one way valves and the return plumbed back in the collector..

The ATL Setup




My fuel cell with one pump mounted in the plate...

 

This is while, imo, its always good to ask, as there is stuff out there, that not everybody knows about.

 

Any more pics or details of the ATL setup ? Cant make any sense of what that's supposed to do ? There are no trap doors for fuel to get into that chamber ? Or is that just one part of something else ?

A well designed tank with internal sump/collector and the pumps mounted as you have is by far the best way to do it. Certainly the neatest. I assume the pump pickup is extended low in the tank ? What have you used as a seal around the pump ?

 

A single gravity fed 044 will not supply enough fuel for a genuine 600bhp on the dyno, proven many a time on the dyno.

Twin standard pumps would be more than enough but due to the standard push fitting being hard to come by we tend to use 2x 044 with a lift pump in tank or in standard 2wd cradle, escos 023 or a standard pump 2wd

It's a little overkill as that will supply more than enough fuel for 800bhp lol, but they're a good reliable pump you won't have any issues with what your going with it's what I'll be using on my car

 

how do you account for ad youngs car then?

 

Not sure but could prove it tomorrow in front of you if you wanted. ask martin hadland what happened with his afr's on his own engine with 1 gravity fed 044 on a -6 line

 

No need his made 677.4 on a dyno lol i very much doubt there making it up

 

On a single 044 wow! We're doi something very wrong

 

No idea your the tunner but the car has one 044

 

Pressurised through a swirl pot you can see a fair bit more, I don't beleive near 700bhp even pressurised so how that's being done I've no idea

 

I'd rather have too much fuel, than not enough

 

Too much fuel when designed badly will also give problems.

 

Very quick sketch of how I made mine, the ATL system is lovely but very expensive...the whole system is housed in the standard bag tank plate...

I made a cylindrical collector, same depth as the tank, fitted two non return valves in the bottom (to allow fuel in and attached the return from the rail back via a flexible into the collector internally...we only need a single pump on the car, the pump is sandwiched at the swage with an 'O' ring to seal it and a pickup attached to the inlet to the bottom of the tank/collector. I then bolted it all together underneath the plate to fix and bolted it all in the top of the bag tank as normal...

Quick but rubbish sketch...the middle bit is my poor attempt at a pump...lol



The product in demon thieves might explain it better...

So the ATL piece is actually an external item. Not something to go in tank ?

Wondered how the hell fuel from the tank would ever get into it with no openings if it was an in-tank piece !

The problem some run into by returning fuel directly into such a small collector, and one that seems to have little access to the main tank's fuel, is they just create a heating loop for the fuel. Unless it's absolutely essential, I wouldnt be returning all of the hot fuel from the engine bay back into the collector.

Most proper internal collectors have a trapdoor style arrangement on all of the sides to allow fuel in, but not out. These openings are usually quire large too, so the normal motion of the car will ensure fuel is always forced into the collector.

 

If you need a twin pump kit i have a brand new ATL going cheap

 

And a swirl pot
