(Sorry, this is going to be a long post!)
After reading some posts about changing the Regina Fuel Pump I felt ready yesterday evening. Thought I'd share my experiences before I forget about it. I sure want to forget it because it was one hell of a job. I mean compared to what changing a fuel pump ought to be.
I bought a new fuelpump and the large round rubber ring at volvo. (1001 swedish krones!) Mistake number one. I should also have bought the sock-like filter that sits on the bottom of the pump. This is not included. So stupid...
So, off with the plate in the trunk and off with the left rear wheel. Started working with all of the hose clamps. They were not hose clamps anymore. They were rust! Remember, I'm from Sweden. We have winter 6 months a year and they put salt on the roads...
There were 4 hoses. One big that the fuel enters the tank from and one little smaller (for ventilation?). No problem. Then there were the 2 fuel lines. The return line was clamped. No problem. There were plenty of hose so i just cut it off as near as possible to get a new fresh end when later mounting. The other one (the pressure line to the filter under the car) sat on a strange rotating connection and there were no hose clamp. This hose was another type. A thin stiff inner hose inside with a normal looking softer rubber hose on the outside. What the hell should I do with this one i thought and finally I could not think of anything other than cutting this one off too.
The electrical connection could be traced to a connection way up by the left trunk lid. Pulled it and finally got the wires out and free.
Now the huge collar could be loosened to free the whole setup. Counterclockwise turning and wiggeling the unit finally got it out. Puh. The sweat was running. We have had a couple of days now with around 30 Celsius! Not used to that kind of heat! Looked at the watch. Holy shit, 2 hours wasted already.
Ok, on with the new pump on the funny looking gizmo. Had to solder the 2 electrical lines. (Why the hell couldn't they have some kind of intelligent connections instead.) Put the unit back in the tank. Remembered (thank god) a post saying "what ever you do, put the rubber ring into the tank first and not around the unit as first comes to mind!". Smeared vaseline to the unit and there it was! Put on all hoses with new clamps. The "pressure" line though was impossible to get on its weak looking plastic connection (nipple?). (Is it called nipple in english or has that to do with women only?) Warmed it up good (not with a lighter!) and put silicone spray on the connection. Pressed it on as long in as I could and clamped it too. Ready! Did it work? Connected the battery. Turned on ignition. Yes! a whirring sound! Hope and pray that this was the problem after all this work just for changing a fuelpump. It was sure better and simpler in the old days!
