Have a look here .. https://www.driven2automotive.com/blog/ ... uel-pumps/
The copy I have seen didnt have the helicoil insert on the inlet. It worked ok still, was in a bosch box and looked legit from all the packaging.
Personally I am a fan of in tank pumps. So much quieter than the old '044, but they are a tried and tested design. Have used a proflow 340LPH but ran out of pump (pressure dropping around 5PSI from target under full load and 250LPH) and now using a Walbro 450 high output (part number is F9000274). These are newish to the market so maybe not copied so much yet. Got it from MTQ. You also need to calculate the flow requirement of pumps under boost, as fuel pressure increases the advertised LPH of a pump drops.
