So i'm wanting to get a radium engineering surge tank when the time comes to upgrade my fuel system and the only problem i see, is that the surge tank only comes with -6an fittings. The only hoses i've found that mate to a -6an fitting are 3/8's.

Further more, the stock hard lines are only 5/16's.

What i was wondering, is, will it be a problem converting the hard lines using 5/16 to -6an fittings? In other words will having both 3/8's (ss braided lines) and 5/16 (hardlines) cause issues?

Was thinking about getting these

I would assume i would need 6? Two at the fuel hat on the hanger (one for feed, one for return). Two where the stock rubber hoses from the tank first meet the hardlines. And finally two more at the hardline ends in the engine bay. (feed that goes to fuel filter, and return that comes from pressure ragulator.

I'm probably thinking too much in to it than i should, but any advice is appreciated.
