well if you have fuel system in your car ,, check the the Hoses ,, if they are big ,, for sure u will lose pressure
check the hoses ,, are they 4 an or 6 an or 8 an
i got a theory i use it myself ,,, if i use Welbro 255 inside the TANK ,,, + Bosch 430
with 8 AN Hose from the Bosch to the Fuel rail ,, i will lose pressure ,,, so i will use 2 Bosch
so check your hoses they might be to big ,,, i tried my Theory here in my country ,, and i guess i am right about it ,,,
hope that info will help u
