I hope the brains in this group are going to provide me with a good (and relevant to my question!) answer here :-)
The diaphragm fuel pump on my Hyundai 2000 si petrol genny has split - after only seven months in service (which seems a bit cr*ppy to me) and I can't find a source of new diaphragms, only replacement pumps. Now, I do know that' replacement', rather than 'repair', is the order of the day but, if they only last seven months, then its going to end up being very - expletive deleted - expensive over a few years :-( Making a new diaphragm is well within my capabilities; when I learned my trade as an apprentice( all those years ago) we made most of our gaskets, joints (NOT 'spliffs'..lol..), seals - and even the occasional diaphragm for the old petrol pumps in our cars .. but in those days there were probably half a dozen local shops selling sheet material; so, I've just spent most of the afternoon on the telephone, talking to various guys who invariably said 'well, I remember when we used to hold that sort of stuff *but* .. either <there's no demand today> or <we can only stock the things that Head Office tell us to hold>' which was really not a lot of help for me. So, I'm stuck unless one of you guys, or gals, can suggest where I might be able to buy a square foot, or two, of reinforced nitrile rubber sheet (or anything else suitable, or better, for being immersed in unleaded fuel) - which is about 0.3mm thick; the actual diaphragm has a maximum diameter of 57mm - that's about 2ΒΌ inches in old money <g>. As I needed to get the genny sorted, asap, I've just got up from the barrel I'd been laid over and, very reluctantly, ordered a replacement fuel pump - I'll chase up the warranty argument once it is sorted! This is actually the second problem I've had in two weeks - the genny ran poorly and then wouldn't start at all; investigation showed that the spark plug cap, secured on the thread of the plug by a tiny spring clip, had been vibrating and the wire clip had worn away the thread on one side so that it no longer had anything to grip on to.. and eventually it just fell off! This necessitated the purchase of a new plug as well as a new cap. Whilst checking *that* out I then discovered where the oil was seeping from - it looks like the valve box cover gasket has failed as well (the oil loss is not great, just enough to make a mess in the baseplate, which then seeps out onto the deck through the openings). Its been like that for at least four months I reckon, so I guess that Hyundai won't be getting any 'highly recommended product' comments from *me* in the near future :-( Trevor [Non-text portions of this message have been removed]
