92 240 struggles to pick up fuel at 1/2 to 1/3 tank.
EDIT - TITLE IS SUPPOSED TO SAY 1/3 TANK, NOT 2/3!
My ‘92 240 surges and stutters, especially around left turns, when it’s burned 8 to 10 gallons of fuel out of the tank. The car has done this the whole time I’ve owned it, but since the fuel gage didn’t work at first, I wasn’t aware. It runs great on a full tank!
Since getting the car I’ve replaced the following fuel parts:
- The main fuel filter - just for maintenance
- The fuel sender, in tank sock filter, and in tank fuel pump (I used a Taiwanese sender and Airtex pump and made triply sure it was all wired right and working before it went in) was all done at once to get the fuel gage working again. The wiring had completely broken off the sender.
- The fuel pressure regulator, because the old one was leaking fuel into the vacuum line.
None of those made any difference. What’s the most likely culprit here? Main pump? Evap system?
