| Post subject: | Making a fuel tank |
Any tips on making a fuel tank? What matirial? Thichness? Design tips? Thinking about a sub tank for the LWB Sierra, and maybe a couple of sill tanks for the Rangie. I have access to a gulitone and folder at work so may as well make some use of it Cheers Rick |

Most factory tanks are about 0.8mm thick black steel which is then zinced but they have allsorts of corrugations for extra strength. Aftermarket tanks are just flat sheet so need to be a bit thicker EG 1.6 - 1.8mm. Work hard on the design so you can have as many folds and as few welded seams as possible. I'd be incorporating a swirl pot and baffles if making a tank from scratch, but a sub tank doesn't really need them. Not sure where you'd get the fittings for sender unit etc.. Maybe chop up an old tank... CAREFULLY. |

Most of the boat shops like Bias Boating, Whitworth etc. sell neat looking fuel gauges want the senders are designed for varying depth aftermarket application |

I have this on my to-do list as my factory one is all beat up now. I was going to combine a bash guard and larger tank into one. ie, make the bottom plate thicker so it is dent-resistant. I have a 2" body lift so was going to make the tank higher aswell to extend the capacity. Be my guest on stealing my ideas so I can copy you

Baffles in the Rangie sill tanks maybe, as they will be long and skinny. Sierra..... don't know. Subs would feed into the main with lecky fuel pumps, so wasn't going for swirl pots or guages. Make the subs smaller than the main tank. As for design, was thinking two 'U' shaped halves welded together, is you get what i meen. |

U shaped halves sounds the goods best would be if you could press all four sides from the base this would be ideal but u would need a specific press or folder.. as for material stainless is best don't need any coatings that will eventually deteriorate as for thickness go for 2mm plus would be plenty strong and easier to weld |

I bought a VS commodore tank off ebay and took the mounting flange, swirl pot, in tank pump, sender etc and fitted to my long ranger. The VT ones look to have a good top mount one where the pump, sender and swirl pot unbolt as one. The top mount idea is a bit of a pain though. The mounting flange came out after drilling just 4 spot welds. |
