Random questions, if you've recently bought a repro. tank may be able to answer some of them. Relates to a 1983 1.8, from end of production and more or less bog standard, it's likely even the original tank. Not in bad nick, but going to change it as it's stood in excess of 10 years and there's now a sticky tar like coating on the inside. Below is a copy of the 7zap schematic. I'm not finding much in the way of other useful images on-line to compare against. I understand there are dfferent tanks and that it's the K-Jet. / Diesel one I'm supposedly after. Have read there is (or was) a swirl pot in these, partly borne out by there being a lidded plastic box affair in mine that the filter (28) sits in. Unfortunately I couldn't get you a good image, but I'd describe it as visiually akin to the one on MK2's, less all the pump gubbins. The yellowed filter pictured is seated in it. This repro. tank is from a seller on eBay - I'm guessing it's a view of inside the tank through the fuel level float aperature? Hard to tell if that's a latter day alternative to a swirl pot, or it's instead just a cup for the filter and there is none. On those filters... There are replacements available (now blue if it matters) but any images I can find have 'For Diesel Only' molded on them. The mesh in the pics also seems to be much less fine a weave than the original - despite what the adverts say are they suitable? I've salvaged everything from the old tank, including the flap at (27)... it seems to be a sort of non-return for fuel that enters the tank via the filler pipe. Do modern repro's have this or do you re-use the original? It's got it's own part number and was relatively easily removed. Also, the bracket at (1D)... is it on all tanks whether GTI or not, I may be missing it?
