So, do all the high flow pumps (walbro etc etc) get the s#its with low fuel levels? I took my stock one out which was doing pretty well on 14psi and would only 'surge' with really low fuel levels 5% etc. First, I put in a second hand walbro GSS340 def genuine, and was getting bad surge at 15% and pinging on boost, so I decided that was shot. A good deal came up for an AEM E85 340lph, so I have put that in but I'm getting surge from about 15% again, no pinging on boost, seems very smooth, slightly less noise than walbro which is good. Is this everyones experience?
Happy Birthday Puff.
