NDP Posted October 16, 2019 Report Share Posted October 16, 2019 I recently had my original fuel pump for my 1972 Triumph GT6 MK3 replaced by a new pump, supplied by Rimmers. After fitting I tried to start the engine but it wouldn't do so. The mechanic who fitted the new pump said that it was flooding the carbs and fuel was spilling out of them. The Triumph has recently gone through a comprehensive rebuild and was running fine until the fuel pump went (According to the AA mechanic who towed me home). The carbs have been through a complete refurbishment and again were performing fine until the fuel pump issue. The mechanic said that although the fuel pumps looked very similar, the new one was bigger. I asked Rimmers about it and they said that the spec was a bit different to the original but that it was the correct replacement part for it (Part number 213577). Has anyone out there used this replacement part on a Triumph GT6 MK3 with any success, or otherwise? Also I now feel like getting my old pump refurbished but kits to do so are only available for the earlier types of pump fitted to GT6 MK1's. Does anybody know of someone who refurbishes MK3 pumps? Many thanks for all replies. Link to comment Share on other sites More sharing options...
Paul H Posted October 16, 2019 Report Share Posted October 16, 2019 Hi I had similar issues with my Vitesse mk2 so refurbished my old one . Easy diy job though if your valves need replacing this more difficult to do Paul Link to comment Share on other sites More sharing options...
Gary Flinn Posted October 16, 2019 Report Share Posted October 16, 2019 Some of the new Reproduction Fuel pumps provide too much pressure I'm afraid? A N.O.S. original or refurbishment of your your old one maybe the way to go, or a Fuel pressure regulator. Gary Link to comment Share on other sites More sharing options...

Pete Lewis Posted October 16, 2019 Report Share Posted October 16, 2019 the only thing to make the pressure is the coil spring under the diaphragm , wondr if they can be swapped over ??? Pete Link to comment Share on other sites More sharing options...
Paul H Posted November 1, 2019 Report Share Posted November 1, 2019 Ebay has a Glass topped fuel pump https://www.ebay.co.uk/itm/184016365139?ul_noapp=true and looks to be worth refurbing Paul Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 1, 2019 Report Share Posted November 1, 2019 you can at least replace the parts in a glass top, some later ones had the valves staked in place , which is a challenge they are a good pump, used on many makes in their day we swapped arms on a Vauxhall spec pump , its easy to make what you want from what you have on these pumps Pete Link to comment Share on other sites More sharing options...
johny Posted November 1, 2019 Report Share Posted November 1, 2019 There seems to be two models of replacement fuel pumps with this part number. These pictures are from Paddock and Rimmers respectively and I wonder if its one particular type thats giving these over pressure problems. Mine was the second type and has worked perfectly....

NDP Posted November 1, 2019 Author Report Share Posted November 1, 2019 Mine is the second type as well. Still trying to get it to work properly. Next step having a look in the bottom of the Stromberg carbs to see if any dirt has come from the old pump or fuel pipes. Fingers crossed. Link to comment Share on other sites More sharing options...
Adrian Posted November 1, 2019 Report Share Posted November 1, 2019 I replaced mine with the first type and has been working brilliantly. Maybe a bad batch? Link to comment Share on other sites More sharing options...
