I think I need to replace my electric pump in my 90 v10. is there any tricks or tips anyone has before I go bench press this 1/2 full tank of gas. looking to get an ac delco pump. I have power at connector by tank during "on for 2 sec" and while cranking but no sweet hum of the pump. So I assume its toast. Was thinking I might do the cut a hole in floor to access the sending unit but trying to figure out the correct location for the hole could end up being a cluster f. and it would be better to drop the tank. Luckily my truck has no rust so it should be a clean drop but looks like it could be a p.i.t.a.
