Not sure how you wold think beefy vu tank would fit let alone work with all the differences.
I think sender units are different although been too long since had tank out of vr or vs ute...do remember anoying twisty technique getting it back into swirlpot though.
Do know vp ute has return line on side of tank & feed only on sender unit like vl or early vn sedans & want to say vr & vs has feed & return on sender unit.
Could be wrong but don't recall them having silly return line hose to swirlpot like sedans whose swirlpot more centre of tank instead ute swirlpot more to left close to sender unit.
