Through-Front-Hood fuel fill, need some ideas on how to Options

[naro914]

Hi all
this may be a better topic for the Paddock, but thought I would start here. Many of you have cut a hole in your front hood to allow for fueling without opening the hood. I REALLY need this on Papa Smurf for racing.

So...can you show me pictures and tell me what you used/bought and where you got it to do this conversion?

TIA!

I used a fuel door with a deus(sp) 1/4 turn to open... Kits are out there at lots of racing sites... But I have stock tank.... You may have to but a neck extender on a fuel cell depending how its mounted..





bad pic,, I was moving the car.. the only one I can find with the fuel door..

This is not a hard thing to do for a cell. Never did it for a stock 914 tank.

Bought everything from FuelSafe when I ordered the cell.

Did this on a 356A outlaw with a custom fuel cell. When I ordered the filler-plate, I also ordered a neck extension and a rain/overflow collar with a drain hose. My pix are at home and not available for several days... I'll post the fabrication/installation pix when I get there.

1. Measure where to cut the hole.
2. Measure it again and cut the hole.
3. Measure the angle to weld on the cap socket, taking into account the cap handle if it has one.
4. Weld it onto the extension.
5. Cut the filler-plate hole and mock up the extension with the cap on. I held mine in place (in the filler-plate) with BIG magnets after cutting the hole.
6. Weld or braze the extension into place and mount the overflow collar/drain.
7. Prime and paint the assembly and bolt it on.
8. Go racing.

I had the cell built with a valved purge tank just in case he ever wanted to run with FI and gave him the valves to keep with the car.

Took a day

Frankly I want to do this for my car too, but the extension will be about 12-14in long and has to be integrated into the hood outlet for support at the top. It'll be more complicated if I want to install a locking cap... tempting on a street car but a PITA. I'd like to just modify a cap and weld it to the bottom of the extension, then put another cap on the top. That would almost be trivial.

I have no idea what would be allowed on the track, but here is how I did mine using the stock tank.

New 100mm Blau repro caps are available from VW parts dealers. Check Bughaus. The filler neck will need to be extended slightly. Go to a local diesel mechanic and ask them for a scrap piece of 4" exhaust tubing. I used a v-band exhaust flange to get the 4" pipe set on the tank. I soldered some stainless mesh from McMaster to bottom of the 4" pipe to keep random debris out of the tank. For the overflow catch can, I used a $3 pet food bowl.

The hardest part to source is the Blau filler neck. Dave at TRE has them. He can actually sell you a soup-to-nuts through the hood filler kit if you don't want to figure all of this out on your own. If I had to do this again I would just buy his kit.

Here are a couple of pics that were taken as I was test fitting and cutting everything up on mine.

I used a 2000-2006 Audi TT fuel door.

Here is one Fuel door

should have mentioned - stock tank
Might have to call TRE...

iamchappy did a really nice job on his. Here's the link:

You can see it on page 13...he probably details the build in prior pages.

the light weight version:

Here is a 110mm Blau stainless steel cap with a GT handle. The cap came with the matching base. Then I had an extension welded on and the Factory EO flange so I can bolt it to the stock tank

Here is mine. Simple hole dimpled into hood.
