Friday I had a track day cut short; mid day the car acted like it was out of fuel. Upon further inspection it appears that the transfer pumps within the fuel cell stopped working. They are getting 12v of power, none are turning on. So that leaves me with a question:
I wonder how many have been working, potentially the car had been working with only 1 or 2 pumps filling the reservoir, or maybe just 1? found it odd they are all dead, but certainly explains the issue encountered. I have a receipt from the purchase of the car that shows the Fuel Cell and Lift Pumps all being replaced in 2022; things fail I suppose.
Well, I got the fuel cell open and took out all 4 transfer pumps, the fuel cells foam is perfect, and the cell is clear of any debris, low pressure pump filters were clean of any debris. Connected each pump to 12v's and couldn't get any of the pumps to turn on. I think they are dead. (The cars main pump and reserve pump work as expected, however with no pumps filling the reservoir the car runs out of gas).
Does anyone have a place to get these low pressure pumps? I'd like drop in replacements to utilize the AN lines and Electrical Connectors. I will start making phone calls tomorrow but if anyone has a starting point for me i'll go from there.
If anyone was wondering the above pumps were discontinued 4 years ago.
With the help of a distributor for Premier they were able to source 4 new pumps that will be plug and play with the 6an, and Bosch connector on the pump.
