| Stop Censorship |
| The Music and Movie industries attempt to disable the internet and truncate your freedom of speech using US legislation nicknamed SOPA, PIPA and as of April 2012, CISPA. |
| ACTA is just as bad (perhaps worse) and and an attempt is in progress to get it approved by governments all over the world. |
| The DMCA law in the US is equally bad and was written by the same industries but I don't document the law or its bad effects on the world's people here. |
| See my censorship web page with its links to more information on how vital it is to stop PIPA, SOPA, and ACTA. |

David A's Europa |
The main concern about a modern fuel system is that it is high pressure. So if something goes wrong one is spraying fuel all over. Lots of it. So be very careful.
The fuel system here is pretty standard, though specific to the spaces in a Europa. The main components are the right-hand fuel tank, a high pressure fuel pump mounted very low, a fuel-rail (for the injectors), and a fuel-pressure regulator for the fuel-return (on the fuel-rail). There is a small fuel filter in the pump inlet (these pumps are not meant to pump any grit at all) and a larger fuel filter (Canton) on the pump output (the high pressure side). The fuel-pressure valve is set to about 3 bar.
It probably does not matter much which fuel pump you use as long as it develops at least 3 bar (42PSI) of pressure. I bought a Bosch fuel pump which was pretty expensive ($230). In retrospect that was probably overkill, and in fact it was the replacement for the part number I ordered at NAPA, not the original part number. It has worked fine so far.
I have a fuel-on-off switch on the dash so I can have the ignition on yet no fuel pump running. Very handy for doing wiring work. The switch controls a relay, the switch does not have to handle full fuel pump amperage.
All the high pressure lines have stainless steel coverings and use AN-6 fittings.
As a separate circuit the right hand tank has a thin line leading to the left hand tank so both tanks empty simultaneously. Do not join the balance line with the fuel inlet of the pump! If you do that both tanks feed the inlet and only one the release, so you will quickly fill and then overfill one of the tanks...
I did have to remove the right hand tank and weld on two new steel AN-6 fittings. The original tank outlet became the pump inlet. A new fitting near the bottom became the inlet/outlet for the tank-balancing. A new fitting near the top became the fuel-return tank-inlet.
I made an aluminum plate to mount the fuel pump and then mounted the plate to the very thin fiberglass. I thought that was a bit more secure than bolting the pump to the thin fiberglass.
The fuel pump picture shows the lower tank connections too.
