cliff.b Posted May 6, 2021 Report Share Posted May 6, 2021 Changing my air filters with standard Spitfire 1500 airbox and it only had gaskets between the box and the carbs. Just wondered if it should it also have gaskets between the filters and the box and are they supposed to be fitted dry or with some gasket sealant?

Pete Lewis Posted May 6, 2021 Report Share Posted May 6, 2021 no gasket on the outer face https://www.canleyclassics.com/?catalogue=triumph-spitfire-mkiv/1500&diagram=triumph-spitfire-mkiv/1500-air-cleaner-twin-carb-engine pete Link to comment Share on other sites More sharing options...
Bob Horner Posted May 6, 2021 Report Share Posted May 6, 2021 I thought both, not just outer face - the diagram that Pete posted shows that doesn't it? Or perhaps I misunderstand what Pete wrote. With no seal between the inside of the box and the filter, it would draw air from the box, not through the filter. Just dry seal in my opinion.

Colin Lindsay Posted May 6, 2021 Report Share Posted May 6, 2021 On my GT6 there are gaskets between the filter box and carbs only; I'd assume that the filters should seal adequately against the inside faces of the metal box - which is compressed around them by the mounting bolts - so it doesn't require any internal filters. I reckon it wouldn't cause any problems if you wanted to fit them inside the box too. Link to comment Share on other sites More sharing options...
johny Posted May 6, 2021 Report Share Posted May 6, 2021 just replaced mine (see other thread) and they each came with two gaskets for installation in the box. I suppose you have to buy the box to carb ones separately but mine were good enough for reuse... Link to comment Share on other sites More sharing options...

Pete Lewis Posted May 6, 2021 Report Share Posted May 6, 2021 the 1500 filters shown only have a opening on one side the stromberg filters have opening both sides hence from whats shown ( without a filter to look at) the 1500 is sealed on the outer face so no gasket , if its both sides are mimiced then you would need to seal the outer against the airbox face or you may suck unfiltered air through the gap below 1500 filter ...one hole one gasket Pete Link to comment Share on other sites More sharing options...
cliff.b Posted May 6, 2021 Author Report Share Posted May 6, 2021 Many thanks for all opinions. As it turned out the gaskets were the least of my worries. One of the mounting bolts wouldn't tighten down on reassembly as the carb thread was stripped, sorted with a longer bolt & nut for now. After re-assembly I had a petrol leak from one of the short flexible pipes that takes fuel to the front carb. It looked ok superficially but on removing the covering the rubber was completely perished and obviously moving the connecting pipe had split it. Replaced with new hose and then found that there was petrol dripping from the front carb now. Replaced that one as well but still dripping which I found was due to the connection from the float chamber to the jet being loose. Obviously that issue was already there and I hadn't noticed which probably explains the slight whiff of petrol. In hindsight, probably a good thing the first obvious leak led me to find it. Other fuel hoses look fine but will now be replaced ASAP. As with various other things I have found on this car, I struggle to understand why so much attention to detail has been applied in some areas of its restoration but so little in others. I have come to the conclusion that it was completed by a different person, but irrelevant really as I bought it expecting work to be required.

Pete Lewis Posted May 6, 2021 Report Share Posted May 6, 2021 when you've torn all your hair out you will get to like the car ha ! there has been some rubbish fuel hoses on open market places the gold std is gates barricade and thats had some supply hic ups club shop sell it when its available much sold behind the counters of some factors is just short life junk hopefully you have read on here the problems of rubber slivers these get cut off the inside of junk hose when pushed onto the metal pipework these little sods can play havoc with the float needle valves by blocking the small inlet or jamming the needle to ake more floods Pete Link to comment Share on other sites More sharing options...
Badwolf Posted May 6, 2021 Report Share Posted May 6, 2021 is Barricade as prone to slivers as other stuff, and is there a practical way to avoid them...apart from don't fiddle with the pipes (I know, leaving myself open to more ridicule!!)

Just cut the hose properly; if you saw with a hacksaw or repeated cuts with a knife you'll end up with slivers. A very sharp long bladed knife which will cut through in one pass makes for a much cleaner cut. Lubricate the ends of the metal pipes with Vaseline or the like before pushing the pipes on - this prevents damage when being pushed onto a dry pipe which agai shaves small parts of the pipe off.

Pete Lewis Posted May 6, 2021 Report Share Posted May 6, 2021 we never had them in the past i put it all down to the state of the rubber barricade is a tough hose material and i think is better but Colins clues should eradicate the little sods dont let Doug know about the vaseline he gets all excited Pete Link to comment Share on other sites More sharing options...
dougbgt6 Posted May 7, 2021 Report Share Posted May 7, 2021 It’s pushing the pipes into the rubber that cause the slivers. So the less sections of pipe and rubber the less chance of slivers. I’ve replaced the entire run between pump and carbs with one section of rubber. Uncle Pete told me that, I think he wanted me to try it to see if it worked. It seems to, although I did have some backfires recently which I’m investigating today. Is KY jelly as good as Vaseline?

Pete Lewis Posted May 7, 2021 Report Share Posted May 7, 2021 yes less connections equates to better reliability even with KY ingress and rubber does not take on as much heat as metal pipework , dont like braided hoses you cant tell when its stuffed and most fuelling snags come from crap rubber hoses stick to professional quality hoses not chink rubber marked as R9 or other nasties the stuff in a blister pack at the local parts centre is generally ........rubbish Pete Link to comment Share on other sites More sharing options...

Ok, so buying certain that can be difficult to find of very expensive on the bay is fine but with the poor reputation for lots of stuff I try to use it as little as possible. I know some items from the big suppliers may not be any better either . . Link to comment Share on other sites More sharing options...

Same here; my local guys know it needs to be ethanol-proof and sell me the modern stuff off the roll. I had a work colleague totally wound up one day when he asked why the petroleum-type stuff was called K Y Jelly; I told him it was an anagram of J Y Kelly who was the Irishman who invented it. He probably still believes that. Link to comment Share on other sites More sharing options...
Badwolf Posted May 7, 2021 Report Share Posted May 7, 2021 Ok. Stupid question of the week coming up, following Colin's post about his local motor factors. If modern fuel pipe is ethanol proof. Up to E10, then why are we all obsessed with using Gates fuel pipe. Surely any modern fuel pipe of the correct diameter should be ok. Even pipe lifted from a modem scrappy, should be ok for us. I am missing something here, sorry, long morning grocery shopping so please forgive...but please put my sad brain out of it's misery.

I would agree with you, most modern fuel pipe would be superior to our needs ( low pressure). From the numerous problems people have reported having I guess the pipe they have been sold isn't ethanol proof despite the sellers claims.

PeteH Posted May 7, 2021 Report Share Posted May 7, 2021 I can see where B-W is coming from. Halfords, one would assume, supply for "modern" cars. All of which must run on E5 or E10?. Therefore one could reasonably expect the product to be "fit for purpose". ? Almost the reverse of the situation where an O/E product would be Better?.

johny Posted May 7, 2021 Report Share Posted May 7, 2021 I think a lot of issues come from urban myths that are based on something that happens initially or occasionally and there ever after gets spread as being a major problem... Maybe even foreign powers are involved😵 Link to comment Share on other sites More sharing options...
