| What are people using for fuel cells in their Gremlins? Preferably something that is a fairly direct replacement for the stock tank and can use the stick filler. This is for a stock body. |

Years ago when using a stock tank I put in a weld in drop with two AN fittings for fuel pick up...https://www.summitracing.com/parts/cee-4041 You will have to copy and paste the above link in a search bar like google. ------------- AKA(AMC BOYS)Rob |

| Haven't had a good look at the tank yet, but already has a patch soldered on the bottom and it looks like it might be leaking elsewhere. Would prefer not to blow myself up trying to weld it, so if there is an easy off the shelf replacement, that might be a better option than trying to find someone who can repair it for me. |

| No off the shelf option that I'm aware of.I put a sump on mine, fixed all the holes then lined it with red kote. Soak it in soapy water for a couple of days and the gas fumes will go away. Any good radiator shop can do all of this for you if you don't have the tools. |

Let's hope I can make one of these work: https://www.summitracing.com/int/parts/jzp-260-008-01" rel="nofollow - https://www.summitracing.com/int/parts/jzp-260-008-01  Radiator shop wanted $400 to clean the tank plus another $135 to coat it if needed (Australian prices) and then I would still need a new pickup and sender. |

Trying to work out the best way to install this thing. I didn't really want to have any fuel lines in the passenger compartment, but by the time you put a 90 degree fitting on top of this fuel cell for the fuel outlet and vent line, you would need to space the tank about 75mm down from the floor in the back and you still end up with the filler line running through the cabin.  The plan is to use something like this in the stick filler location to fill the tank:  The question is really if there are any issues with running the fuel line through the cabin for a short distance? |

Mount the tank under the trunk area. Figure out where to mount it where the filler neck will line up with the hole in the rear panel. The only thing that will come up into the pass. compartment will be the vent and the filler neck. You can enclose one or both as the fuel line will be under the car. ------------- former NHRA #1945 former IHRA #1945 T/SA |

| I have pretty much come to the conclusion that the fuel outlet will need to be moved from the top of the tank. |

You can enclose the fuel outlet by taking up minimal space in the package area.Use two 90 degree fittings out of the cell.That would be the easiest and most economical route. I'll see if I can find pictures of my old gremlin to show how it worked for me. Ed F. ------------- former NHRA #1945 former IHRA #1945 T/SA |

| I did think of boxing the line in, but figured that buying an extra bulkhead fitting and moving the outlet to the side of the tank would be a better solution. |

So, I've made it this far, another trip to CMP to get an extra bulkhead fitting and blanking cap. Outlet is now on the lower left hand side of the tank with the pickup tube running to the rear centre of the tank. Also made some mounting straps and spacers for installation: As usual I did some more research after the initial purchase and discovered the following, which won't necessarily affect me now but could come into play in the future. 1) This brand of tank is not US DOT approved, so not legal for road use over there, I'm assuming that would also apply here. 2) The safety foam inside is not compatible with E85, I'm not planning to run E85 anytime soon, but had assumed that the plastic tank would have less issues in that area. 3) This type of tank is not FIA approved, because they mandate a tank with an internal bladder, I don't think this is likely to affect me, not sure at what level you need a FIA approved tank. Also not approved for some other forms of largely irrelevant motorsport, on the other hand it is also approved for some other forms of largely irrelevant motorsport. 4) These tanks are made to comply with SFI requirements for drag racing, however individual tanks need to be certified, which is an additional step should a certified tank be required, which I assume is the case at some advanced levels of drag racing. Regardless of this, I'm sure it will be just fine for my immediate needs. |

Done the final install, hopefully this will do the job:  Just working on the filler now. I will have to build a bigger motor to make use of the 1/2" fuel lines. |

Final piece of the fuel system puzzle, one of the guys at work was kind enough to make this filler for me: Did have to sacrifice a non-pristine factory cap in its production, but it certainly finishes off the back of the car, well except for the pre-existing panel damage that is:
