Cost to replace fuel pump on 1990 Mercedes-Benz 300TE

My car is actually a 1988, but I wasn't given that choice

Fuel Pump, Electrical part# 0020918801 $264.00
The time is about 1.5 hours. So 1.5 x whatever the shop hourly rate is.
The fuel accumulator also suggested when you replace the fuel pump.

Thank you for your quick response.
Now, can you tell me if it's okay to use regular unleaded in the 1988 Mercedes? One mechanic says yes, the other says no.
You are very welcome.
MB recommends premium fuel. Lower grade will cause performance issues.

That's certainly a $500 job. You really need to use premium fuel in your MBZ. Good luck.
