Pressure Tube Oil Pump for Volvo B18/B20 Engines
19.06.2026
When overhauling engines in cars like the Buckel, Amazon, P1800, or Volvo 140, problems sometimes arise from minor details that the mechanic hadn’t even considered beforehand. Take, for example, the oil pump pressure pipe, which—in its usual location in the oil pan—shouldn’t be exposed to any harm and is always well-lubricated and protected from corrosion.
But there are exceptions: If the car or the removed engine has been carelessly stored for a very long time in a somewhat damp environment, even an oil pump pressure pipe like this can sometimes become rusty. This, of course, poses a major risk, because if the pressure pipe has even the tiniest hole, the oil pressure drops dramatically. Not to mention that, of course, no engine likes to have rust particles in its oil pressure lines or bearing seats.
Of course, this isn’t the only possible reason for replacing the pressure pipe: The B18 had a different oil pump and a different pressure pipe. Neither is available anymore. Sometimes, however, the oil pump itself is worn out; if the permissible radial play is exceeded or there is too much tooth flank play, the pressure delivered drops significantly.
In that case, the B20 oil pump—which is still available—can be used in the B18 without any problems. However, this also requires replacing the pressure pipe with the one from the B20.
This part has been out of stock for quite some time; when needed, the only solution was to resort to used parts. Since these are becoming increasingly scarce, we have commissioned a reproduction of the pressure pipes for the still-available B20 oil pump.
To ensure that the oil pressure in your freshly overhauled engine is always good, the pressure pipes are now available in our shop under the part number 1018422.
