before I went for a remap I made a few changes to the car and this included swapping the standard fuel pump for a Walbro 255 which I swapped over myself.
I managed to spill a bit due to forgetting to take off the fuel cap and thus causing the tank to self purge and this caused a fuel smell in the car for a week or two.
now, 2 months on, I still get the occasional whiff of fuel and the thing that concerns me is that with the old pump when I was getting low on fuel and took of the fuel cap to fill up, there would be a 'woof' noise as the vacuum in the tank released but now there seems to be no vacuum and no noise.
is this normal or have I not sealed the pump mounting plate back into the tank correctly giving me a bad seal?
any advice would be welcome as I am now a bit confused.
