I just got a '91 740 wagon after my '92 240 was involved in an accident. I'm still getting accustomed to the wagon and the Regina system I suppose. The owners manual states that the fuel tank holds 15.9 gallons. I have yet to add more than 11.5 even when I thought I was almost empty. And when the gauge gets almost to the empty mark it starts hesitating when I let off accelerator and then accelerate...my 240 with Bosch system never did this. I have even run out of gas because the needle was close to empty but the warning light was not yet on. My question : Is there a problem with the sending unit in the tank or what? It does not seem to be keeping accurate readings especially on the full end and empty end. Surely it does not have a smaller gas tank than listed in manual. Input about this matter will be appreciated. I certainly do not want to run out of gas again. James B.
fuel gauge or sending unit in '91 w/Regina?

You will need to take the pump & sender unit out of the tank to check the fuel pick-up strainer and the pipe coupling from pump to main fuel feed. Your car has only one pump which is in-tank and more powerful than the in-tank pump on the two pump system (LH). The tank should hold 60 Litres which is about 13.2 gallons (imperial) or 15.85 gallons (US). I suggest that the low-fuel warning switch or the indicator lamp in the gauge is not working. It should show when approx 6 Litres (1.5 US gallons) of fuel remain in the tank. The sender probably has a contact problem which causes the wavering symptom.
All the best, Peter.
