611 Posted March 11, 2022 Share Posted March 11, 2022 So now the Opel is back up and running! one issue i need to sort if fuel tank venting. So im after some thoughts and advice from any of you injection experts out there! My setup is this: In tank fuel pump, outlet and inlet go in the top of the pump and the original A inlet is blanked off. On the A they have two vent pipes at the top of the tank that on the original loop up and connect to a fitting on the filler neck, with one them then coming down with a tube that vents to the air at the back of the tank. I have looped the two vents at the top of the tank together so that is effectively blanked off and then took the filler neck outlet down to the original vent to air location on the back of the tank and added a small motorbike breather fitting which is supposed to let air in/out to stop any build up. I don't know if the fuel filler cap is vented? The issue i seem to have is that i get quite a bad fuel smell from the area of the vent and it seems worse if i have been doing a fair bit of cornering. I have checked and everything seems leak free and the filler hose is new. Im going to be doing some more investigating but thought while i was there it would be best to make sure i have the right setup. Also if the car is just sat in the garage you do get quite a smell of fuel when you fist open the garage if its been a few days? Again, no leaks that i can see. I have attached the diagram from the manual of the original tank setup and the late A's in Germany had the injection so a pic of that setup and the breather fiting. Any thoughts and help would be great. Andy Quote Link to comment Share on other sites More sharing options...
