Try searching the forum for keywords such as bogging, fuel, pump, filter and such. In short you should do a volume test, change the high pressure filter if it's below spec and probably reinstall the OEM pump as it's likely of much higher quality than the replacement part. As for the fuel level gauge, try doing the test described in the service manual (page 9-33). The resistance seems to go as low as 4Ω, so either you didn't measure yours properly, or something's the matter.
