[Guest danny_samb]

Hi guys done a track day in the hood today was great fun. On a long right hand corner kept getting fuel starvation, what can I do to cure this

Thanks

Hi Danny

 

Just fit a swirl pot.

[steve in stockport]

Easiest thing is to just keep the tank full all the time, nowhere for the fuel to surge to if it's full

[Guest danny_samb]

Surely I would have to come in every few laps and top up then, what's involved with fitting a swirl pot

[Guest Alan_builder]

Swirl pot

Low pressure fuel pump.

High pressure fuel pump if injection.

Plumbing.

 

Take a feed from the fuel tank to the low pressure fuel pump towards the top of the swirl pot.

Take a feed from the swirl pot to the high pressure pump.

Take the out out of the high pressure pump to the fuel rail.

Take the return from the pressure regulator to the swirl pot again near the top.

Take an overflow from the top of the swirl pot to the return on the tank.

 

If you have carbs, substitute High pressure pump tor a 2nd low pressure pump and the injection rail for the carb return and overflow.

 

Just remember the swirl pot needs to be mounted like a sky scraper, small footprint and tall.

[Guest danny_samb]

Could I mount it in the boot above the tank. I'm running injection, so can I use the current pump for the low pressure, iv seen a 1litre swirl pot on demon tweeks

[Guest chris brown]

Yes the swirl pot can be mounted anywhere. If you allready have a low pressure pump feeding your high pressure injection pump then just plum the swirl pot between the two with the low pressure pump feeding into the top and the high pressure being fed from the bottom, the return from the fuel rail should return back to the swirl pot somewhere near the top.

What pumps should I use if not, what about the facet cube and the facet red top or silver top

Thanks

Running a dohc 8v with efi

[Snapperpaul]

Facet cube to swirl pot your original injection pump from swirl pot to injector rail

Return fuel from rail goes to swirl pot overflow to tank

just scroll down and there is a nice picture to show how it should look when done

[Guest danny_samb]

Thanks for the help guys, I'll get the bits ordered, how would I wire the low pressure fuel pump so that it works with the original pump

[Guest zerorace]

so it runs all the time with the ignition on make sure the feed has a fuse and it is easy to get to, also check the rating of the pump it will need to deliver more then the HP pump can use at full throttle.

[Guest danny_samb]

I have seen they do 3 versions, road, fast road and competition, which 1 would be best, engine is just standard 2litre dohc, fast road be suitable, I just need a good feed from ignition live then,

[Guest zerorace]

something like this i would think should do

 

the injection pump should be good for 130l/h to 165l/h dependent on the model if it is the sierra one
