Fødepumpefejl er en af top10 fejl på volvoerne. (Det er en tysk Bosch komponent, så det skal jo gå i stykker før resten )

Fuel System Pre Pump 1978-1993 240 Models
The pre pump is a low-pressure, high-volume pump that sits inside the gas tank and supplies fuel to the main high pressure pump under the car. When it fails, symptoms include poor idle quality, hesitation when accelerating, reduced fuel economy, loud humming noises emanating from the main pump and accelerated wear of the main pump. Faulty pre pumps can also lead to hi amperage loading of the fuel pump electrical circuit resulting in blown fuses and or failed relays as mentioned above.

200 series B20, B21, B21FT, B23, B27 1978-83 1276330
200 series B23, B230 1984-93 1389721

Den tidlige af de to pumper forsyner bla en 984 og 979 pumpe så vidt jeg husker(K-jet turbopumper), så mon ikke den er et godt udgangspunkt.

Citat:My experience tells me that once the cam with the lumpy idle is selected, the thinking mostly stops. Decisions then are based on lowest price, looks, ease of installation, coolness factor, the 'latest thing' syndrome, peer pressure, old wives tales, and bad advice.
Citat slut.
Hold kæft hvor er det sandt!
