fuel pump?
 

I have a 88 240dl and I recently replaced the on frame fuel pump but whats the pump part number for the in fuel tank one and is it high or low pressure

the in tank pump is a booster or transfer pump, low pressure, it just serves to deliver fuel to the main pump, which develops the pressure for the fuel injection.

the main pump is 9142044 (and the non-return valve which should probably be replaced with it is 1326899).

the tank pump is 3507436, and the pickup strainer/filter which should probably be replaced with it is 1274817

thank you very much I'm super new to Volvos more of a 4runner guy
