Default A couple questions for those using WRX gas tanks in their swaps…

I have a couple questions for those who used WRX gas tanks (or maybe any newer tank) for their swap projects (ours specially involves mostly 02 WRX parts into a 96 Brighton).

First, what fuel filler neck did you use? I have the one from the WRX and I would assume that I need to use it but I was not sure. I say this because we swapped the emission stuff along with the tank, and the type and number of hoses coming off the fuel neck is different than in the Brighton. The fuel necks look to be similar in shape but before we pull the old one (the screws holing it on have seized and it will require drilling to get them off) and replace it, I wanted to make sure it would work.

The second question is how people have gone about connecting the fuel supply lines. The one from the WRX tank utilizes a quick disconnect fitting while the lines from the Brighton are the standard hose and barb style. A quick search has not turned up any quick disconnect to standard hose adapters and I have a few other ideas for a solution to this problem but none of them seem quite perfect. I was hoping someone might have come up with an easier and better solution to this already.

Thanks in advance.

Is the use of WRX gas tanks not as common as I thought or are these just not problems others have had when doing tank swaps?

No, I had an issue with my tank swap as well, a very similar one in fact.

However, my swap is all 05wrx equipment, so I'm unsure whether the 02-03 emissions stuff is the same.

We had trouble with the filler necks and the charcoal cannister system, we tried deleting it and the way the hoses hooked up without it created some problem where the tank would not fill correctly. We ended up using the complete 05wrx emissions system, you just have to get creative with placement of the charcoal cannister and stuff. Also, we used the 93 filler neck, the wrx one won't fit. I can't remember off the top of my head what we did with the discrepancy in the number of hoses on the filler neck.

As to the hose connectors, a trip to the hardware store, and several adaptors connected together, solved that problem.

Email James at East Coast Swappers, they did my swap and can tell you in greater detail the issues we had and how they got around them. Reference the zebra, they will know which car you are talking about haha.

Today I installed a 06 STi tank into a 95 coupe. The tank and charcoal canister all bolt right in to the coupe. Nothing different between the two cars.
The filler neck will fit too.
What you need to do is take the outer metal ring (closest to the filler cap) from the 02 car. Place it up to the project car and line it up with the 3 round holes(like you were putting it together).Now use the 3 square holes. Mark them and drill em out. Mount the filler neck to the new drilled holes. Now everything will fit perfectly.
Good luck with it!

hmm, maybe theres some difference between the 93 and 95, or the coupe and the 4 door. Don knows more than I though, take his advice over mine haha.

Thanks for the responses and information. I guess I will go ahead and try to fit the WRX filler neck as it will certainly make routing the rest of the emissions system easier (due to the already mentioned differences in the hoses coming off of the fuel necks). As a bonus, the integrity of the Brighton fuel neck is somewhat subject where as the 02 neck looks to be in perfect condition. We had a small fuel leak prior to starting the project so this should ensure we get that taken care of.

I took your advice today sheepdog and just headed over to NAPA. It looks like by combining some parts, we can probably put something together that will get the job done. Also, there must be something different between your 93 and my 96 (or alternatively between the 02 and 05) because the entire emissions system from our 02 fit perfectly into the 96.
