Extreme Fuel System.. Need Some Quick Pointers

[Tocchi]

im going to be ordering some more parts (another MP-4703 fuel pump, filters and fittings) to my fuel system now the aussie dollar is good against the USD.

already have:

Magnafuel ProStar EFI 750 Fuel Pump (665-MP-4703) - Magnafuel MP-4703 MagnaFuel ProStar EFI Fuel Pumps

Magnafuel ProStar EFI 4-Port Regulator (665-MP-9940) - Magnafuel MP-9940 MagnaFuel EFI Regulators & Fittings

Siemens Deka 2433cc injectors

running methanol

but this is where I need some help now...

the MP-4703 fuel pumps have: inlet/outlets of Dash-10 fittings.

the MP-9940 fuel reg has: inlet/outlets of Dash-8 fittings

my Nitto fuel rail has: inlet/outlets of Dash-8 fittings

should I run:

1) Dash-10 lines, with Dash-8 -> 10 adaptors onto fuel reg & fuel rail

or

2) run Dash-8 fuel lines, with Dash-10 -> 8 reducers on the fuel pumps?

and regarding fuel filters...

-- fuel filter links --

what's the difference between PRE-filters and AFTER-filters (apart from the micron count?)

because I can get a 74 micron PRE filter, but 25 micron after filter (as seen in the link)

cheers

Id run the -8 fuel line with the reduces on the fuel pump from -10 to -8. My reasons being is for cost. -8 fuel line will be cheaper and easier and neater to work with and you will only need reduces on the fuel pump which would be cheaper than buying reduces for the fuel reg and fuel rail. Cant help with the fuel filters though.

I talked to my tuner (Ovaboost), and they told me -8 is fine. they use that on their drag cars.

so here is a rough example of how the fuel system will be done. should work a treat
