Milo500 Posted August 12, 2016 Share Posted August 12, 2016 Hi guys, got a bit of a big dilemma Just chaged the fuel pump to a walbro 255, turns out it had one in there before haha, but since that I have been getting horrendous mpg. As in I have a 10 minute drive and it goes down about 3-4 bars on the fuel gauge (without even going near the throttle, just pottering around. I can't smell any fuel, so I have no idea. Any help very appreciated Cheers, Tom Link to comment Share on other sites More sharing options...
Mike2JZ Posted August 12, 2016 Share Posted August 12, 2016 Take fuel hanger back out and check you didn't damage the fuel sender when you put it in whilst changing pump. It's pretty fragile Link to comment Share on other sites More sharing options...
j_jza80 Posted August 12, 2016 Share Posted August 12, 2016 As above. After Whifbitz fitted my new Walbro pump, the gauge was reading wrong. But it seemingly sorted itself out after a few days. Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 13, 2016 Share Posted August 13, 2016 The fuel level sender has probably come out of a little clip when you removed / refitted the pump and sender unit. Take it out again and have a very careful look and you may find this is what has occurred. Link to comment Share on other sites More sharing options...
