So, I ordered the piper 481-666 fuel pump, its also listed as a FACET 478360 The threads on it are 1/8" NTP threads, the fuel pump I removed is the exact same pump but with 1/4" NTP threads? I can find no mention of this ever being a piper blessed pump. So... My fuel lines are 1/4" NTP so I either need an adapter or new T fittings what's the correct way to do this 1/4"NTP to 1/8" NTP or just get new T fittings that re 1/4-1/4-1/8 ? I look at the salvage pumps for sale and they seem to be mixed and matched as to what is installed on them. can these fittings be purchased from auto zone or do i need some sort of aviation fittings?
