    The Assembly Manual gives instructions on how to modify the gas tank so you can close the hood. I’ve cut the piece out and now will “attempt” to weld the top of the filler neck back onto the tank. I’ve purged the tank as best as I can and will fill er up with water before I weld. That should help prevent any lingering fumes from igniting. Oh! I’ll also be outside in the middle of the back yard with fire extinguisher and cell phone at the ready.

     

    Don’t try this at home kids!

     

    Pictures of the before and after to follow when completed.

    Allen,  I really don’t know how you are mounting your tank but let me tell you my latest turn in my wire wheel story.  After completing cleaning the wheels I went to put my spare in the “trunk” and (wouldn’t you know) it doesn’t fit.  The damn thing doesn’t fit!!  The center spindle on the wires is about 1″ too tall and it holds the hood up.  My spare is supposed to sit atop the gas tank which, in my MiGi, is mounted longitudinally up front.  At Carlisle, I admired the extra under hood room that those kits with the tanks that sat crosswise just forward of the “firewall” had.  Guess I’m gonna tear my tank out and investigate if I can mount it 2″ lower than it is.  Else I’m going to have to install my spare on the engine cover and do away with my somewhat slick continental cover and possibly my luggage rack.

    Roy,

    My tank mounts just in front of the front firewall. I sits in a box that drops into a cutout in the front portion of the body tub. But the 63 tank that I’m using has a 3-inch or so filler neck. I have to remove at least an inch and a half. I cut it down to the boss on the tank and kept the top inch with cap to weld back on. Should fit fine. I could have purchase a new tank but I would have to do the same with a new tank so figured I’d save myself the cash to purchase other necessitiesd.

    Allen,

    I have the CMC/fiberfab vw kit. It has the pre 68 tank with the shortened filler like you are doing. I am not sure how much they cut away, but when I tried to put a new gas cap on it the hood hit. I had to rob the gasket out of the new cap and put in the old. If they would have cut another 3/8 – 1/2″ off it wouldnt have hurt. Pretty close in there between the filler and hood.

    Well as I posted earlier, here’s a few photos of the gas tank after I welded the filler neck back on. The height now from the top of the tank to the top of the gas cap is 2 13/16-inches.

    Nice job, Allen.

    Roy: yeah, you’ll want to hang that spare out back. Going to take some fabrication though.

    Ed, I’ve been eyeballin’ it.  Need one splined wire wheel adapter to do my plan.  Either side will work since I have 2 extra spinners, one left and one right.  

    Allen.  You’re a lot better welder than I am.

    Roy…thanks for the nice words.

     

    Mike…the next time you fill up, could you measure the distance from the tank flange to the top of the gas cap? Hopefully I cut enough off of mine. The assembly manual really doesn’t give a measurement. Its jus tsays to shorten it.

    Allen,
    Nice job on the welding – I wish you were closer and I could have you help welding my new project.
    I am welding in pans right now and doing other chassis repairs and my welding is bad.
    I tried to get by on the cheap w/ a Harbor Freight 110 mig welder and it is not working to well.
    What type of welder are you using? I am thinking about sucking it up and getting a 220 
    Lincoln mig 180 from Home Depot but at at 700.00 to 800.00 it is a bit steep.
    Sorry to Hi-jack

    Allen,
    I agree the  cmc manual is not much help. It says “as short as possible”. I went out this A.M. and measured mine. With no cap on from top of tank to top of filler neck was 1″. When I needed a new gas cap gasket I ordered a new cap. I swear it was almost 3 times as thick as the OEM cap. It hit the underside of the hood. I had to just get the gasket for my old cap. This may have been something in the original build of the car causing the cap to hit, but there isnt much room between the cap and the hood.

    Schu,
    im not trying to hijack this thread, but I have the Harbor Freight Mig 151 that is a 220volt welder that will use gas or flux core and it does a decent job with either lincoln or hobart flux core wire. If you are using the Harbor freight wire that came with your welder, toss it and try a name brand wire. I also have a lincoln AC220 amp welder that if you are careful and use a 1/16  6013 rod will do a decent job on thin metal.

    Schu ??? I have a MIG welder from Sears. Its a straight wire feed welder. The one for the gas tank was borrowed from my buddy. 220V MIG with Argon Gas.

     

    Mike ??? Looking at my photo, the distance from the lip on the tank to the top of the gas cap is 2 13/16-inches. I guess I need to shorten it up some more. Dang!!!  Unhappy

    Allen, mine was taken with no cap on. I think you will need to shorten more. Maybe someone else with a CMC/Fiberfab can measure to verify.

    Schu, I have a Lincoln stick welder (220 volts) here if you want to borrow. I bought it to do stuff & have as yet done nothing with it. Come up for a cruise and I’ll beer ya. Or maybe I’ll bring it down to you at bugout. Thinking of flat-towing her down this time, though it pains me to say that.

    Looking at the assembly manual there is a small part of the illustration that shows the top of the filler neck down with 1/4-inch next to it. Looks like some more shortening is in order.  Oh well, like Ed says “TD Replicas: unmatched fun-per-$ ratio”.

    Okay…removed the filler neck and cut some more. From top of tank next to filler neck to the top of the gas cap is 3/4-inch. At least that’s the dry fit stack up. Will weld tomorrow, clean up the rest of the tank and paint it Sunday. New photos when completed.

    Okay. The 2nd filler neck shortening has been completed. I think 7/8-inch will be good. Here are the photos.
