Still looking for anyone else with the “tank empty at 1/4 Guage mark” but looks to be a rare problem that I’m assuming was done from improper installation with the O-Rings. |
The fuel pump and level sending unit are two parts of an assembly inside your fuel tank so I don’t think the fuel pump is causing your fuel level issue. My guess is that your sending unit was either damaged or the float arm was bent during the installation of the new pump.
First question I want to ask is: Did you or someone else install the aftermarket fuel pump. And just so you know, I have the same year car and same aftermarket fuel pump installed and did it myself, and noted that there was a discrepancy in the instructions that went with the new pump.
Second question I want to ask is: Did you end up stacking the O-rings that came with the new pump or did you use the OEM plastic spacer from your OEM pump along with one O-ring?
Last question, which involves the discrepancy that I mentioned above: Did you use the lubricant that came with the new pump to lube the pump O-ring(s)?
