whats the easiest way of making a reliable fuel system....
ive been looking at running a swirl pot and braided lines ect with 044 for lift and and another for main pumps and a symtec billet filter but works out like £600+....
is the standard fuel system any good and what are other options...
it needs to flow enough fuel for 2bar boost on greys.... and be reliable

lol Yeah I think your going a bit over the top Mark, standard fuel system runs 6 bar and when your EFI that is fucking loads as you only need 3.5bar at the rail, so plenty of overhead.
I would just stick a new pump on and check (or renew) your fuel pump wiring so it has a good reliable battery voltage and maybe leave the MFI accumulator in line if your worried about surge.

standard cossie fuel pump is all you need ,thats what richie runs with 2.1bar boost on a t34 and greys.
and im on the same pump too but i may have to change mine to a 044 soon.

Just remember achieving a high fuel pressure is not the same as achieving a high flow rate which is what you want.
You could achieve 10 bar of pressure by putting a pin prick sized restrictor in the fuel line doesn't mean to say it can flow enough fuel for a 300bhp engine.

You are very correct sir. A good standard pump with first class wiring will go some before running out of juice. 2wd cossie I believe is better but if a new pump is being purchased I would go 044 just never run them dry or they pop real quick.
I was just commenting on peoples obsession with fuel pressure achievable not flow rates.

cheers guys well ive been looking into this now and matt lewis motorsport do a standard size upgrade for a rst for £95 and i can keep all my standard carrier ect...
my main concern is the return fuel pipe realy as its a shitty thin plastic one for mfi then cut down to fit to the fuel regulator and will a fiesta turbo fuel reg be upto the job

If I doubt use your standard pump to run a swirl pot and a .44 to run from there. You need to ensure around 4psi min at the swirl pot. For mine I run a pressure switch in the swirl pot mounted to a big light on the dashboard. If the swirl ppt runs below 4psi the light comes on telling me to shut down. With 1.5 Litres in the swirl pot this gives you plenty of time and warns of a failing lift pump. Obviously doesn't warn if the .44 goes, but every little helps.

There is also a lot of argument about where the returns should dump their fuel. I chose the tank to alleviate heat build up as much as possible.

yes mate, two pumps required, although the lift pump has no real load and will flow enough fuel at zero pressure, the main pump has to be man enough for the high pressure side, a new k-jet pump will be well up to the job.
