im planning on running stainless steel braided fuel lines

the fuel pump im planning on using has 3/8 npt inlet and outlet.

im also going to add a 3 way valve that has 3/8 npt inlets and outlet.
and a -6an inlet to 3/8 male outlet for the inline fuel filter that i plan on attaching straight to the fuel pump.

from what i can tell my fuel/water separator is also 3/8's npt.

and from what i'v looked at online 3/8 is equivalent to -6 an hoses.

i have a grinder and a compressor for cutting and shooting air to clean up any debris left after the cut.

so im planning on ordering -6 an hoses and a wrench to put all the pieces together. but what other size wrench do i need to tighten my fittings?

i have a set of standard size and metric size wrench's so i was wondering if i could just use something i already have. any thoughts. and thanks


planning on using summitracing an fittings just cuz its in my budget.

what other tools might i need? if i order the -6 an wrench with my fittings.

do my sizes sound about right?

vise + correct size wrench.  mexi wrenches just destroy everything. 

wrap electrical tape around your cut, use grinder to cut it, spray liberally with WD40, slip on fitting.  spray wd40 inside hose, press fitting inside hose, start threads and then use vise + wrench to tighten all the way.
