I have had a fun adventure with the fuel pumps on my ’88 Volvo 760 Turbo Wagon. First I had problems with no fuel pressure when the temperature has in the 90F range and the humidity was rather low. The main in-line pump quit and I installed a good used OE style main pump. The pump worked good until it got hot again with low humidity.”
Number one tip: You don’t need to remove the tank to replace the in-tank pump. There is a access cover that can be removed to get to the tank sending unit. Now that the tank is out it may be easier to get it back in if you remove the access cover and remove the fill tube hose before trying to install the tank. Also attach the hoses from the access hole. The access cover is found in the trunk on 7xx/9xx sedans and under a floor panel behind the rear seat on 7xx/9xx wagons.
