I am going to replace my fuel prepump in a 79 240. I am going to remove the
battery beofre doing the work. Any other saftey tips? Sure don't like working
right above all those potentially explosive gas vapors. Also, my local parts
store says there is a GM pump that works fine for old 240s but costs a lot
less. Anyone tried this? Unless I get confirms I will get the OE Volvo part.

Make sure the tank is at least 3/4 full...

Sounds strange but true as there is less space for vapours then and its the
vapour that is the problem. Apart from that the usual no smoking, no spark
producing jewellery etc etc....

And have a fire extinguisher nearby just in case.....

Good Luck!!!

Greetings,
I know your talking about the prepump which is just as important - but the
below was my experience with the main pump.

When I replaced the main pump on my '80 240gl a few years back I was scared
by the price and found repco could supply a much cheaper one that fitted.
Looked similar fitted but didn't have enough pressure for the car to run. I
returned it and got my money back and went to petroject in Brisbane they
supplied exactly the same part (number identical) for much less than volvo.
In Australia the '79 I think (which my sister had) had a different main pump
to the '80 model I had.
Do a search and save the money. Volvo have to source many of these parts
from somewhere.

I just changed a pump and prepump in a wagon a few months ago. I took the tank
out. Trying to do a good job. Disconnect the battery for sure. I also
disconnect the wires to the prepump which you would have to do anyway. The
hardest thing for me to do was taking the collar off the inlet tube/gas
tank(remove the gas). It was an awkward reach. After I got the tank down I
lcleaned around the bung hole very carefully and then using a brass rod tapped
the bung free. Getting the prepump out was like threading lights on a tree. The
prepump assembly looks like some sort of mech. alien spider. oh, and then put
everything back.Save the rubber gasget the new one may not exactly fit, and you
want it to.
