I'm currently attempting this install and having bit of trouble. I have the Walbro installed in the top portion of the white fuel assembly thingy. I removed the 5 tabs and two tabs on the pump itself but I'm still having fitment issues. I can only get 2 of the hanger clips to grab and the other 2 just wont reach. How essential is it to have these clipped? Can I rig something up that'll keep the assembly from opening even if the two clips aren't attached?
