Not really sure, as I only got 1 bill for the whole lot!
Maybe slightly more than I expected, TBH. :-/ Perhaps the exchange rate has made it so. Worth giving Teilo a call to see what he can do IMHO.
Also be aware that 4 hole tanks have a fabricated filler hose a bit like a hydraulic hose with ends crimped on - so you need to know where everything is going to end up before you know how long it needs to be!
Multivalve tanks you can cut filler pipe to length as it's just copper / polyflex tube. In fact for a 4 pot I would probably go for a multivalve. I went 4 hole because it looked marginal on power with a V6.
They can fill quicker too, on the right pump!
You will also need rubber hose for the vapour and vacuum connections.
Best to see what turns up and we'll sort out what else you need.
