Thanks in advance, I’ve had issues with the car stuttering, especially at freeway speeds recently. I have to admit the fuel tank did run quite low prior to, even though another car has had the same issue. Wondering if the fuel is contaminated from point of purchase which was the same for both cars or if the fuel pump is on the way out. I had a look at the current setup which has the return line blocked. Do I order one with or without the return line? Ive read several posts have used a Bosch pump ending in 070 with success.
