Swirl pot install caution

Good evening all,

About to do a 2.3L swirl pot install on a R33 Gtst, already have the hardwear, running a single Bosch 044 pump with a Bosh 040 lift pump.

Now the install itself if got down to a T, however upon further reasearch on the UK GTR forum's, it's been mentioned about using a larger return line from the swirl to the main tank, in order to prevent the swirl pot from cracking. Any substance to this claim as I'd assure that even by going on something like a -8 that the size of the connection on the fuel sender would still restrict it anyway. 

Essentally my goal is to do this install without the need to modify the existing sender. All other aspects seem straightforward enough but this is the only thing that has me hesitating. If anyones fitted a swirl to a 33 and modified the sender any info would be appreciated 

*for the record the same forums said that mine line from lift to swirl and swirl to fuel rails would be fine on the current diameter.

will be fine with -6 line. there isnt any pressure (well minimal) in swirl pot as it is returning fuel back to tank when its full.
