Richard Crawley Posted April 21, 2004 Report Share Posted April 21, 2004 No longer having access to my previous source, I would like to get hold of my own fuel line pressure test guage & 'T' piece adaptor. Can anyone advise where I can get one? Quote Link to post Share on other sites
tim_trinda Posted April 21, 2004 Report Share Posted April 21, 2004 Try Revington RTR4007 Tim Quote Link to post Share on other sites
Richard Crawley Posted April 21, 2004 Author Report Share Posted April 21, 2004 Try Revington RTR4007 Tim; Thanks for the response but that’s a rather rich price for a pressure gauge & a brass ‘T’ adaptor aint it? Anyone got any other sourcing ideas or a good second-hand one they want to sell. Quote Link to post Share on other sites
jemgee Posted April 21, 2004 Report Share Posted April 21, 2004 There is one on ebay at the moment http://cgi.ebay.co.uk/ws....y=27383 sorry I don't know how to hyperlink (?) Quote Link to post Share on other sites
jemgee Posted April 21, 2004 Report Share Posted April 21, 2004 Apparently I do! Quote Link to post Share on other sites
Richard Crawley Posted April 21, 2004 Author Report Share Posted April 21, 2004 Mike, thanks for the lead but what's on offer here is not a fuel test guage, it's a vacuum guage. Although this was also an important (less so) part of the PI test kit, the vendor is missrepresenting it's function & use. Quote Link to post Share on other sites

JohnC Posted April 22, 2004 Report Share Posted April 22, 2004 I have a Stauff gauge which I use for checking the overdrive pressure (400psi ish); With the correct adapter I'm sure it would do the job on the fuel line as well. I had my (overdrive) adapter, and a short hose, made up at my local hydraulic specialist - the kind of place you'd go to get Aeroquip hoses made up etc.. They also sourced the gauge. From memory, the whole kit cost something in the region of A$100-120 (£40-50), but that was 8 or so years ago. Hope this helps. John Quote Link to post Share on other sites
tim_trinda Posted April 22, 2004 Report Share Posted April 22, 2004 that’s a rather rich price for a pressure gauge The problem with cheap gauges is that they are cheap, and probably have an accuracy of +/-10%. If such a gauge was used to set the pressure to say 110psi the actual system pressure may be 99 - 121psi. You could however use a cheap gauge and calibrate it against a known good pressure. I suspect the Revington test kit uses a high quality gauge and while it may not be calibrated it is probably very accurate. I've asked Revington what accuracy they are quoting for their gauge, I'll post the answer when I get it. As a matter of interest a £30 0-160psi gauge costs £85 to have the calibration checked! ========= Tim Quote Link to post Share on other sites
tim_trinda Posted April 22, 2004 Report Share Posted April 22, 2004 The Revington gauge has an Accuracy Class of 1.6 per DIN16005, which in plain speak means the full scale accuracy is 1.6%. Full scale is 220psi so at 110psi the accuracy should be 0.8% (I'm guessing here) or less than 1psi. RS do gauges, t-pieces, etc they also do Stauff components mentioned by JohnC. ========== Tim Quote Link to post Share on other sites
tim_trinda Posted April 22, 2004 Report Share Posted April 22, 2004 the vendor is missrepresenting it's function & use. On eBay -- I can't believe it! ??? Quote Link to post Share on other sites
Richard Crawley Posted April 22, 2004 Author Report Share Posted April 22, 2004 Tim Thanks again for the info, the Revington gauge is obviously quite accurate (as it should be for that price) but I will have a look at RS to see what standards their stuff conforms to (almost like being back at work!) before I decide what to do, although I really would like to have my own test kit. On the basis that my car would not respond to throttle at all, I guess the pressure was maybe as low as 90 psi or even less. To get me out of trouble & at least make the car driveable, I tweaked the pressure relief valve blind. A full half turn (good for approx 10psi) made a huge difference & then I gave it a further 1/5 of a turn just to clear some slight hesitancy. It now responds very well & pulls like a train - down my 200ft drive at least! I have the insurance so at least I can now take the last major step & risk a run out to my local MOT station, maybe tomorrow! If all goes well, free tax is the next thing & then, after some cautious local mileage, my first “run out” will be to TRGB, who supplied the bloody PRV in the first place! Hopefully they will check & set the fuel line pressure FOC. Moral of story is don’t trust even a new PRV (or any PI kit for that matter) is set up correctly, you need to check the fuel line pressure once it’s installed. Quote Link to post Share on other sites
Richard Crawley Posted April 22, 2004 Author Report Share Posted April 22, 2004 On eBay -- I can't believe it! ??? Tim I'm a "E" bay virgin; is this par for the course then? There is certainly a "play on words" there in the add but if you read it carefully, it does state what is actually on offer! Quote Link to post Share on other sites
jonlar Posted April 22, 2004 Report Share Posted April 22, 2004 If having bought something on Ebay the description is incorrect/untrue/inaccurate the deal is void. Feedback is posted and the vendor's can be checked by clicking on the number in brackets after the handle http://cgi.ebay.co.uk/ws....3755205 Click on the 120 after my cgjon handle Always try to resolve any dispute before posting negative/neutral feedback. I've just been contacted by a vendor who overcharged postage and is refunding £2. Generally, Ebayers are a good, honesty and trustworthy bunch. I've only had one bad deal.

Richard Crawley Posted April 22, 2004 Author Report Share Posted April 22, 2004 Generally, Ebayers are a good, honesty and trustworthy bunch. I've only had one bad deal. So there are still people around you can trust then! I would like to think so as I am firm believer in &, for at least 3 years, have been a frequent user of Internet trading; like it or not, it's the future & I guess most people don't know the ammount of money you can save on electrical & white goods (sometimes 20%+); Why on earth would anyone go to Dixons or Comet! To date, I have not had any real problems & in some ways, it’s better than the high street when you need to return. But, I have not yet plucked up enough courage to use "E" Bay – if it had been a PI pressure gauge on offer then, needs must, I would have gone for it! Quote Link to post Share on other sites
tim_trinda Posted April 23, 2004 Report Share Posted April 23, 2004 Richard I use eBay both as a buyer and seller with getting on for 400 transactions in total. As a buyer almost everything I've bought has been as described with no problems, the biggest problem is trying to assess the condition of used items. There is a facility to 'Ask the Seller a Question', I use this to get more info and/or pictures, if a seller doesn't repond to these requests there is probably a good reason so I usually don't bother to bid. As a seller, again no problems really, in the last 2 years I've had just a couple of people who haven't paid. Give it a go with a cheap item, its quite painless really - but a word of warning it can be quite addictive!! Anyway back onto the main topic, RS sell pressure gauges with 1% and 1.6% FSD accuracy, for example they list a 63mm 0-220psi, glycerine damped, 1.6% accurracy gauge for £17 (RS number 243-5925). This is the same spec as the Revington gauge, maybe even the same gauge! To buy from RS you will have to set up an account through their Joe public company Electromail (01536 20455) ========= Tim Quote Link to post Share on other sites
Richard Crawley Posted April 23, 2004 Author Report Share Posted April 23, 2004 Tim, thanks, that's a bit more like it. I will give RS a look. Quote Link to post Share on other sites
Roger H Posted April 25, 2004 Report Share Posted April 25, 2004 Tim - that's a great link and you've done the hard work - thanks. As I'm not too technically oriented, why would you suggest the 16 bar gauge in preference to the 10 bar? I just thought the 10 bar may be read more accurately on the dial. - I'd like to get one also and permanently mount it in line. Quote Link to post Share on other sites
tim_trinda Posted April 26, 2004 Report Share Posted April 26, 2004 16 bar gauge in preference to the 10 bar Roger These gauges are rated for continuous operation at 66-75% (pulsed/steady pressure) of full scale deflection (FSD ), which for a 0-10bar(0-145psi) gauge is (95-108psi). Therefore for a permanent fitment it might be prudent to go for a gauge with an FSD greater than 10 bar. Revington use a 16 bar gauge in their fuel pressure kit, hence the reference to a 16 bar gauge. You are right about accuracy, the 10 bar gauge would be more accurate than the 16 bar gauge at a given pressure. ======== Tim Quote Link to post Share on other sites
