sorry. i was thinking that non-return valves were responsible for maintaining pressure on one side, regardless of the pressure on the other. god knows why! that's absolute crap. they just keep fuel running smoothly in the same direction. pressure is related to flow. this is a dynamic system, non a static one. i feel like i've been thinking in 2D, when i should have been thinking in 3D.
I haven't read all this but FSE do two different rated fuel pressure gauges. At least they did when I bought mine.
GTI: good advice from mr.brown, but why not look at it HERE for free It's a lot more precise than the link you posted.
i didn't think i'd offended anybody? i posted the thread because i wanted to make sure that what i thought was correct about the way the fuel pressure is routed around the system was correct. it turns out it wasn't. my bad, as they say. i'm sorry if you did take offence. i was a little offended myself by your assumption that i didn't have enough sense to get high pressure hoses and fittings. perhaps that was the falling out issue? again, sorry if i caused offence. as i've said many times on this forum, i'm just trying to learn and get things right. should i be lambasted for occasionally drawing the wrong conclusions? maybe i sound overly officious sometimes - or a little arrogant. whatever, i don't mean to be. i'm a nice guy really.
Yeah, I was a bit confused myself as to what all your talk of non-return valves was about. Glad you've figured it out.
Top link dude - shame I'd already spent $35 on the real thing! Got the KE-Jetronic one coming soon too
I don't know you at all, you could be a complete spaz for all I know I was trying to help and make sure your car was safe, there aren't many jubilee clip based fittings that can take 90psi. I was slightly offened that you ask for help, even put my name in the thread heading and then disagree with what I said. Then again you did admit that you'd been a bit of a spaker, which puts you way above other forum members who will never admit they're wrong So go on then, give us a , but no funny stuff
thanks. i was advised by the guys at fse glencoe (www.fuelsystems.co.uk) that a good jubilee clip connection over the correct hose was good for up to 11 bar. was he talking pooe? the annodised ends i've been sold as the correct fittings for the 'high pressure' hose seem to be little more than standard jubilee clips on the inside, and i had intended to use standard jubilee clips over high pressure hose in a couple of other places in the very high pressure part of the system. should i be worried about this? i talked through what i intened to do with the guys at fse and they all seemed to think this was fairly standard practice. obviously i'll not be driving around without being sure it isn't leaking anywhere, but do you think it will?
come to think of it, the old lines had a number of jubilee clips holding rubber hose to copper pipe, and a friend of mine did a very similar job with his mk1 16v a few years ago and didn't have any problems.
Mines all be done with hose and jubilee clips, i'm hoping this is okay too. I don't appear to have an accumulator or a filter either
no accumulator or filter? you have a mk1 don't you? (think i remember that from seeing other posts you've made) if so, the the accumulator should be behind the offside rear wheel, just behind the pump. the filter is under the bonnet, bolted to the side of the metering head. not sure how you could have missed either! i'd be a little worried if you have!
I personally wouldnt use jubilee clips for permanent fittings on K-Jet, especially on the fuel pump - dont think they are strong enough for sustained use.
