Engine swap done but problem with fuel lines
 

Hello to all.
I ve just finished my diy engine swap.
I am an owner of two miatas . One 99 1.8 turbo with forged internals, and one 01 1.6 NA.
So I swaped the engines between these 2 because i wanted to keep the clean uncrashed chassis of 01.

Everything went fine except one thing .
Euro spec 99s have 2 lines on fuel rail instead of 01s that have one.
It s obvious that 99s use a returnless fuel system but 01s dont.
What should I do with the fuel lines to make both miatas run smooth ?
Thank you.
