Hi all , How would i set up a fuel cell system in my boot. I will be removing the stock tank (as its rusty) , and will only need a small capacity cell (about 10 to 20 liters) , Just enough to prime my gas system on start up. Will i have to run the pump with a catch can or can i just run a Holly fuel pump straight off the fuel cell. Any advice would be great , Cheers.

Not that I know fuel cells very well, but many race cars use them. Often you can see the external pump on them. So long as the fuel cell has some kind of venting, a Holley Blue should do the job without any trouble. |

Thanks , i agree the holly blue would be the go. I can buy a 19 liter alloy tank for $300 but then I'm unsure of the fuel line. can i use the stock lines modded to fit or will i need new fuel lines all the way from the cell to the motor. There wont be much strain on the system as i will be changing over to gas straight away.
I have holes already in the floor where the towbar mounts and was thinking of putting rubber seals in there with the lines going through. would this be a safe idea or is there a better way. The plan is with the old tank removed im hoping to lower it a lot more at the rear and run twin pipes out the back. more noise the better lol. Cheers |

You could always have those fancy braided lines for the last length to the fuel cell. The only important thing to remember about fuel lines and tanks is 1. no leaks and 2. no heat sources nearby. So long as you have nothing that will cause or contribute to either of these, you can do what you want. However, licencing authorities are likely to have objections to running fuel lines "inside" the cabin; their reasoning is that if you put anything in the boot, it may sever the fuel line. Just make sure nothing is vulnerable to damage |

Thanks for the info , might run some fuel hose off the standard lines to the new tank and pump , going through the boot floor.
Given that this could take some time to organize funds and fit up , and plus the need for a mobile sparky to do the final wiring. I will keep you posted when time comes to complete the job and start up safely happens. I had better get started pronto. |

Actually, I'd simply rig up a connection from the existing fuel pump lead. all EFI Commodores have their fuel pump inside the tank, with the connectors being outside. If you can do some neat an tidy soldering, would be unnecessary to call the auto sparky for that one. By rights, there should only be 2-3 wires going into the tank; one for the sender, and one, possibly two for the fuel pump. All the fuses and relays are already done in the engine bay |

You're always better off at least finding out if you can do it yourself rather than pay someone a lot of cash to do it. Even though I've never seen a VN's sender setup, I know that Holden LIKE simplicity. Less stuff to go wrong lol |

Just contacted a holley pump supplier , and there red and blue models are not compatable with efi.
I will keep looking for a suitable external pump but its not looking like there is one. unless someone knows of a good brand for efi aplication.
Now its more likely i will replace the stock pump , and clean out the rust in the tank. |

Personally, I wouldn't try cleaning out the rust in the tank, but more replace the tank. Fuel tanks used to be made from a kind of sheetmetal they called terne plate; steel coated in a tin/lead alloy not unlike solder. If rust gets under the coating it's very hard to get rid of.
I would ask the likes of Repco and performance shops who makes a good EFI fuel pump. I know there would be many of them out there, as there are many race/drag/street cars running nonstandard fuel pumps. |

Thanks Mechkight73 great info mate , sounds terminal about the rust. I need to get rid of the tank anyway so that's fine. I'm half way through taking the tank out and might have found one , it's a Bosch external fuel pump that's efi only , $183 through a Mitsubishi performance parts store and its capable of up 350 hp which is more than enough for the V6. Plan is Tank first , then pump , then lines and Plenty of beer in between. lol |

Just so long as you don't fill your own "tank" to the brim with beer while you're replacing the tank lol |
