hi guys

hope you can help

i have had the tank and swirl pot fitted with -6 fittings

along with the 044 pumps and filters

i have set up the tank and swirl pot and placed the pumps and filters to where i think i will have them

what do you guys think before i final fit??????

Hmm, i'd be tempted to have the pumps lower than the swirl pot/tank as they are gravity fed, but I dont think where you have them will cause a problem.

sorry mate if i am being silly, you have 2 outlets on the tank, are you using one 044 to feed the swirl pot or are you running 2 red tops to feed it aswell?

fostersice

iTrader: (1)

Lower outlet on tank to filter
filter to 044 pump
044 pump to swirl pot upper inlet
swirl pot lower outlet to 044 pump
044 pump to filter
filter to fuel rail
fuel rail to swirl pot upper inlet
swirl pot top fitting to tank top fitting

Leaving tank upper outlet to blank off???

i was being silly lol..........would it not be better to run the pump's parallel, from tank have a 90 straight into filter,straight connector into pump,then into swirl pot and the same the other side.
think it would look better imo..................

really need to stop working on the car this late at night still if im going to have it running by feb and mot'd in april i need to get a push on,,,, may be begging for help soon

Your going to get a lot of noise with them sat directly on the metal brackets,might be worth insulating them with something

I've put dudble sided tape between the pump/filters and the alloy

Give Alex a call at Pro Alloy. he'll give you every solution you need.

stevieturbo

you are feeding that pump on the right from the top of the swirl tank ???? WTF ???


And looking at that tank design, no way would I ever run an efi pump directly off it. EFI pumps do NOT like trying to suck air.

Use a proper low pressure pump that can handle such things. With the pickup on the tank at one side like that, it will see air.

That's funny as it looks to me that that tank feeds the filter
the filter feeds the pump the pump feeds at the top of the swirl pot
the lower outlet on the swirl feeds the 2nd pump that feeds the filter
that feeds the fuel rail that returns the the 2nd upper inlet

stevieturbo

Your swirl tank feeds no filter.

The main tank feeds a filter and goes nowhere.

Either you dont know which is in or out on the fuel pumps, or something is fucked up.


You do NOT supply a fuel pump from the top of any tank ! Ever...well, unless you were upside down.

Sorry mate have you even looked at the pics or read the post.
I'm still making the hoses
the line between filter and pump is missing as like the post said I'm working on the hoses

right just for you
tank lower out let has I hose that go's to the first filter
the filter will then go into the first pump
that will feed the swirl pot going into the top side inlet
swirl pot lower outlet will feed the 2nd pump
2nd pump will feed the 2nd filter
2filter will feed the fuel rail
fuel rail will return back to the other top side inlet
then the top fitting will join with the top fitting of the tank as I overflow
so where am I feeding anything from the top of the tanks ????

stevieturbo

DUH. do you know which is in and out on the pumps ???

NEVER EVER supply a fuel pump from the top of a tank.

stevieturbo

To make it a little easier for the simple to understand.

fostersice

iTrader: (1)

Pumps are only in place to get hose sizes
what you have pointed out it the pump to swirl pot feed
that pump is round the wrong way in the pic

So it's feeding the swirl pot not the swirl pot feeding the pump

stevieturbo

Clearly it would make a lot more sense to have them the right way round.

And unless that fuel tank has some serious baffling inside, using an efi pump as a lift pump, is not a good decision.

If for whatever reason you encounter a lot of cornering that will throw fuel to the left side of the tank, it will cause problems. EFI pumps should never be allowed to see air.

I see why it looks fucked up now lol
in the pics the pumps are round the wrong way lol

Thanks stevie

I'd say the -6 line from tank to pump, filter and all those 90's wont be doing the pump any favours.

Ideally a min of -8 supply line, with as little bends as possible, and if using bends, nice full flow ones.

Is using an efi pump off that right hand fuel supply a tried and tested format ? I still dont see how that pickup could be safe for an efi pump ?

Aside from that its a very neat and tidy setup.

Micky

As most UK tracks are clockwise,the petrol in youre tank will flow away from the outlet to the 1st pump.When youre fuel tank gets low on fuel it will end up sucking air,no problem if the swirlpot doesnt empty before the fuel runs back to the outlet.But a bit risky if you ask me. Micky

They only make the mk2 tank with out let's on that side and have done for ever and still making them on that side so can't be that bad

it's not a track car it's a road car and only for weekend
so tank will alway be full.

And as for the pump if the 044 motorsport pump are that bad no one would be using them

fostersice

iTrader: (1)

Ps it's a baffled tank aswell

Micky

the 044 pump is gravity feed,so is normally placed below the tank.

fostersice

iTrader: (1)

every mk2 ive ever seen is done the same apart from i have done it with it set up in the middle

stevieturbo

The 044 is a superb pump, when used correctly.

stevieturbo

Perhaps there is some form of centrally located internal collector inside those tanks ? and the outlets we see, arent as functionally crap as they look.

Any details of the internals of the tank ?

fostersice

iTrader: (1)

All I know is it's I race tank and it had baffle panels inside

the guys at ford who raced mk2 escort cosworth did the drawing on how to set up
tank,swirl pot ie what size.and what pumps and filters and where to place them

Keeping everything central on the car

the guys work for fords and raced escort mk2 cosworths I'm sure they know what they are talking about?????

If I didn't I wouldn't have spent Ł1020 on the fuel system
tank Ł200
swirl pot Ł90
044 pumps Ł280 inc fittings
motorsport filters Ł50 inc fittings
10 meters of braided PTFE Teflon fuel hose Inc fittings Ł400

Micky

Keep the petrol tank 1/2 full or more and you'll have no problems with fuel surge.Also means you wont need the swirl pot and can sell it on ebay with one off the pumps and filters too. Micky

How about I leave as is as it's just right,

Lol

your tank is different to mine though ,as in my mk2 where your fuel outlets are mine has a lower baffle directly underneath so it has an extra 3 to 4 inch lower than the base of yours and the pipes go to the bottom so even with a gallon of fuel you shouldnt get any surge,
yours will work but as others have said just keep plenty of fuel in,and i thought 044 was a bit powerfull for a lift pump but proofs in the pudding,looking good anyway good luck

chameleon

iTrader: (1)

have you run the return into the top of the tank???????? i thought that was the breather for the tank to let in air.

Micky

Unless your fuel tank outlet is picking up fuel from the center off the tank its not "just right".

The only reason a twin pump/swirl pot system is fitted is so when the fuel level goes low and the car corners hard causing fuel surge the engine will still get fuel.With youre set up,when the car takes hard right handers the fuel will surge away from the pickup,causing air to enter the fuel line.Hopefully the remaining fuel in the swirlpot will last long enough to continue fueling the engine.But as you say,its only a road car and will be always full of fuel.That kind of makes it a waste of money buying a swirl pot,lift pump and filter in the 1st place.
You should read this thread,will help you understand the main principals.

If youre fuel tank outlet picks up in the center you'll be grand.

what he meant by saying the 044 pump may be bad on your set up is that because its such a high pressure pump, IF you were to do a track day for example or lots of right hand cornering and there is no internal collector in the tank etc keeping a constant supply of fuel to the pump no matter how low the amount of fuel in there, then the pump taking fuel from the tank could draw in intermitant burst of air instead of fuel which will kill such a high pressure pump extremely quickly

Thanks guys for the input.

Turnover your tank has I built in swirl pot that's why u have the small tank at the button

I wanted to have the external swirl pot.

i dont get it, you ask for tank,swirl pot,pump and filter help and when people give thier opinions you dismiss them and tell them your right??
