ablister 31 Posted January 20, 2006 (edited) side top bottom Is this a fuel prerssure regulator or non return valve? I bought it from ebay for like £3 (only reason i bought it!) and was advertised as a fuel pressure regulator but after looking at burton power catalouge, it looks like a non return valve. It has the markings 'FSE97' on it cheers, ali sorry for crap photos, was taken on my phone Edited January 20, 2006 by ablister Share this post Link to post Share on other sites
mfield 20 Posted January 20, 2006 Not 100% but i would say non return valve because it dosn't look like it has the adjustment screw for pressure. Share this post Link to post Share on other sites
Beastie 1 Posted January 20, 2006 If I'm not very much mistaken it's an Apple Pro Keyboard manufactured around 2000 - the other thing looks more like a regulator. I agree that it's unusual not to have an adjuster screw. I haven't seen a non return valve that shape before. Share this post Link to post Share on other sites
Anthony 1,000 Posted January 20, 2006 I reckon it's a fuel pressure regulator from Fuel Systems Enterprises Share this post Link to post Share on other sites
pug_ham 242 3 Cars Posted January 21, 2006 I agree with Anthony, fuel pressure regulator. Usually used when running carbs afaik. Graham. Share this post Link to post Share on other sites
ablister 31 Posted January 21, 2006 https://www.burtonpower.com/pic_viewer.aspx...Way%20Valve.jpg after a quick look on their website, this looks very similar to what i have all confused now! btw, that picture is of a one way valve Share this post Link to post Share on other sites
pug_ham 242 3 Cars Posted January 21, 2006 all confused now!And now, so am I. After a second look I wouldn't like to say which it is, I'm leaning no more towards the one way valve as it hasn't got any means of adjustment for it to be an FPR. Test it & see, if you can only blow through one way, maybe it is a one way valve. (Not that I know if you can blow both ways through an FPR). Graham. Share this post Link to post Share on other sites
ablister 31 Posted January 22, 2006 right, i can only blow through it one way so it must be a non-return valve but i contacted the seller again on ebay and he swears it's a fuel regulator. Anyone with carbs use one of these and are they needed for carb conversions? (a one way valve, not a regulator) Share this post Link to post Share on other sites
mfield 20 Posted January 22, 2006 Carbs have fuel bowls so there is no need to hold the pressure in the line i would have thought ? i might be wrong Share this post Link to post Share on other sites
Guest smokinslim Posted January 30, 2006 My first car, a 1.1 Mk1 fiesta with a small webber carb, kept pressure in the fuel line with the ignition off. Had to take the top off the carb once, got a face full of petrol lol Share this post Link to post Share on other sites
