mk5 petrol smell

[Wheelspin]

in my mk 5 it isn't all the time and only seems to be in the car I smell it, usually when I stop, not when driving..
It will go days without any smell and there seems to be no puddles under the car or smell under the bonnet...it is driving me nuts...
are there easy places things to check ?

How about sharing what you found out for the benefit of the forum??

iv'e got no further with it, the smell stopped until today, I went over a speed bump and it came back for 5 minutes, I am getting the cvs done next week, while it is up on the hoist I'll have a look at fuel lines..

Pop the bench seat out of the back and check the seal on the lpfp. It could be allowing fuel to splash up and out giving you the gas smell until it evaporates. Willing to bet money there will be dried up fuel stains all around the lpfp.

I hate it when that smell under the bonnet drives me nuts too!

I've looked at a couple of posts around here and that pump looks like a easy swap if I do replace it, or is it just a seal o ring that needs replacing...
if I do replace it is there a better option for the pump that will either work better or is a fuel pump there up grade really make no difference..

It is very easy, takes 5 min to pop the rear seat out to gain access to the pump. The hardest part is getting the lock ring off the pump to actually pull it and yes it's just an o ring that needs to be replaced. As far as upgrading goes, unless your going bigger than a K04 there is no need to upgrade, the OEM pump is fine up to those power levels.
