I got mine off rockauto.com , i order alot of parts from here and in terms of customer service and ease of exchange/refund etc on parts they are awesome, like amazon of carparts..
Mine was the spectra one in this list,

Hope the link works doing it off my phone.
I also got a MANN fuel filter that im going to install once it warms up a bit, even with the propane heater in garage is still chilly at the temps we are getting this week.
