Mark Ayling Posted June 25, 2003 Share Posted June 25, 2003 If anyone can help with this it would be much appreciated! Previously I've had trouble with my FSE Valve leaking petrol from the blanking nut on the bottom - I tried threadlocking it once which didn't seem to work, but managed to go for about a year without any problems by using Plastic Padding Leak Fix. After Leon worked on my car, he obviously didn't know about the leak so didn't put anything back on to seal the nut. It started leaking again pretty soon so I got the magic Leak Fix out again and its got me to Le Mans and back and I've also done quite a few miles since, some of which has been quite hard driving. This morning though, I could smell petrol again when I started it up - I looked under the bonnet and there wasn't the slow dripping leak which was there before - it was bloody spraying petrol everywhere! It looked like it was coming out of the top as well, but I didn't get a proper look as I was in a rush so I took the Golf to work. What I want to know is, having just had my fuelling perfectly set up by Leon, if the FSE valve is removed or replaced then presumably it will screw the fuelling up completely and I'll have to get it sorted again? I need to get it sorted asap as I really need the car, not sure what I should do next...? Thanks in advance! Link to comment Share on other sites More sharing options...
mos Posted June 25, 2003 Share Posted June 25, 2003 Yes if its removed it will bugger up the pressure but only if the top nut (adjuster) is altered. You could try some plumbers tape on the thread of the bolts. My fse has just had a new diaghphram fitted as i ruptured my old one. If you decide to take it apart then they are very easy to refurbish its all straight forward. I used an electrical oil pressure gauge before and after refurb to ensure it was set at the same pressure. If you do set the pressure its better done with the vacumn line removed (ie no vacumn) Link to comment Share on other sites More sharing options...
Mark Ayling Posted June 25, 2003 Author Share Posted June 25, 2003 Thanks - but that's beyond my abilities! (apart from the plumbers' tape bit ) I guess I need to establish whether it is just a leaky bolt or whether mine is knackered as well - how did you determine that your diaphragm was ruptured?

mos Posted June 25, 2003 Share Posted June 25, 2003 I was getting some strange noises every now and again and my wideband showed some strange readings on occasion. It really is easy, clamp the fuel supply line, remove the fse and undo 4 bolts. the fse is then apart and you can see the diaphram. All you can do is look at it to check as mine had a tiny rupture. The replacement kit just goes in the same way the old one comes out then tighten the 4 bolts and reconnect the hoses. Link to comment Share on other sites More sharing options...
Mark Ayling Posted June 25, 2003 Author Share Posted June 25, 2003 Nice one, cheers. As the car's not going to be driven until its fixed I might just give it a go! (having a look that is) How much is the replacement kit and where did you get it from? Link to comment Share on other sites More sharing options...
Adam W Posted June 25, 2003 Share Posted June 25, 2003 It's not a good idea to use plumbers tape on fuel fittings, as one tiny shredded piece of it in the wrong place coud easily block an injector I've been told to use Loctite Hydraulic Sealant, I believe you can also get liquid PTFE that you use like Loctite and blob onto the threads before assembly.

mos Posted June 25, 2003 Share Posted June 25, 2003 Good point yeah dont use the tape. Link to comment Share on other sites More sharing options...
Mark Ayling Posted June 25, 2003 Author Share Posted June 25, 2003 Many thanks chaps I've got this stuff called "Chemical Metal" - very similar to LeakFix and made by the same people - which claims it can seal any type of metal and is also resistant against fuel amongst other things. Would that do the job OK? Link to comment Share on other sites More sharing options...
Adam W Posted June 25, 2003 Share Posted June 25, 2003 Errr, I'm not sure you want to use that as a thread sealant, that's more of a filler really. It'll probably do the job but you might never be able to unscrew the fitting again! Link to comment Share on other sites More sharing options...
Mark Ayling Posted June 25, 2003 Author Share Posted June 25, 2003 ISWYM, but its only a blanking nut anyway so shouldn't matter?? Link to comment Share on other sites More sharing options...
Mark Ayling Posted June 26, 2003 Author Share Posted June 26, 2003 OK now I'm really confused! Can anyone give me any more help with this? I've just been out to remove my FSE so I could have a proper look at it. Before doing so I thought I'd start the engine briefly so I can confirm where the leak is coming from. Trouble is, the leak's now not there at all! WTF? Can anyone shed any light on this? How can there be an intermittant leak? If its intermittant then its even more worrying than before - as said in my initial post yesterday the petrol was literally spraying all over the place - I dread to think of that happening whilst I'm driving along blissfully unaware Any help would be most appreciated!

Guest Terry S Posted June 26, 2003 Share Posted June 26, 2003 TBH Mark I would just order a new FSE. Link to comment Share on other sites More sharing options...
Mark Ayling Posted June 26, 2003 Author Share Posted June 26, 2003 Yep, I agree - but I need to be able to use the car in the meantime, if possible! Link to comment Share on other sites More sharing options...
Guest Terry S Posted June 26, 2003 Share Posted June 26, 2003 Look up a company called Glencoe. They supply the FSE's & should be able to next day a replacement. The ting is with thread selant, you must ensure that it is not broken down by fuel. This would leave you pretty limited IMHO. Link to comment Share on other sites More sharing options...
Mark Ayling Posted June 26, 2003 Author Share Posted June 26, 2003 Thanks for the help chaps - I spoke to FSE/Glencoe earlier who pointed me in the direction of one of their distributors, and I have a new valve arriving tomorrow. Link to comment Share on other sites More sharing options...
mos Posted June 26, 2003 Share Posted June 26, 2003 After you have swopped them over strip the old one down and take a look, its worth seeing how they work Link to comment Share on other sites More sharing options...
Mark Ayling Posted June 26, 2003 Author Share Posted June 26, 2003 Originally posted by mos After you have swopped them over strip the old one down and take a look, its worth seeing how they work Yeah was probably going to do that - if it can be repaired would it be worth anything to anyone? The new one just cost me £75 + shipping. Link to comment Share on other sites More sharing options...
