Just logging my research here for anyone who may be doing a similar project.
My ’86 Vanagon fuel tank is leaky and I suspect has a bunch of goo on the bottom that’s causing the fuel pump to whine. So we’ll replace this winter before heading off on our trips in the spring.
I have already replaced some of the line going from the tank to the overflow tanks in the wheel wells and being a cheapskate I hate to buy the full reseal kit because some of the materials are redundant and I would probably save about $20 if I spec’d the pieces out individually.
So I may do that research as well. But in the meantime. Here’s the preliminary price findings.
On the kits, note that Rocky Mountain Westy is the only vendor that seems to include the grommets for the expansion tanks in their kit. Even with these additional parts, their kit is still one of the cheapest, so we’ll likely order from them.
I did the parts vs kit comparison, see chart below. Ordering from Rocky Mountain Westy (who seemed to have all the necessary parts in stock at this time I wrote this), it doesn’t make any sense to buy the individual parts because they come out to almost exactly the same price as the kit.
As far as choosing a tank goes, here is a great thread on thesamba.com reviewing different tanks/vendors.
The Spectra VW3C $148 at Amazon seems to be generally well-regarded on the samba forums and since I have Amazon prime I can have it delivered for free! I would typically prefer to support the smaller VW parts vendors and feel a bit guilty buying this from Amazon but I have dropped a lot $ at the smaller vendors this year, so much so that I have no extra money in my Vanagon budget. So, cheaper wins here.
