[QUOTE="TARM, post: 39818, member: 578"] Point well taken on the gasser comparison and yes I agree reasons are completely different. Refill time was the other part in my post. It is also something I do not know what is the exact answer and depending on mods like Matt speaks of. I simply do not have the hands on or knowledge of the answer. I am speaking of what is the min amount of pressure needed to fully refill a well worked over 400/400% running max usable pulse width @ 2500, 2700, 3000, 3200, 3400 etc RPMS as an example? That is the other reason I can see for boost ref combined with pump life. I believe Dave or someone else from Swamps had posted on this subject recently here on PSA. Further would not a one way check valve that works with air and fluid completely address the dangers of runaway scenario? Maybe there is a reason this woudl not work. But I have found a number of small valves rated for both air, water, and oils. Any reason this would not work as the failsafe to prevent the rupture diaphragm leak back created runaway event? I know the answer seems to be just run a Fuelab pump @ whatever reasonable psi you wish 60-75 whatever as its brushless and running @ reduced speed. I also know you have had great luck with them. The one I have has failed twice now in I think a year. Stuck on the side of the road is still stuck brushless or not. It is also the loudest damn pump I have ever heard of this size. So its going back soon to be fixed again. I think the answer for me as I am not wanting to deal with the fragility of these electric pumps in general is to work on setting up a gear driven pump. They have nothing to burn up, electronics to fry, pressure issues, heat problems etc. The shaft turns and it pumps. The flow climbs with rpms and needed flow. For whatever reason this damn fuel system has been fighting me on the most simple crap. After messing with trying to set fuel pressure I found the gauge sent with the regulator is a POS and simple light twist or tap changes the pressure reading dramatically. Just another stupid issue that's my fault for using what is now clearly a cheap gauge. [/QUOTE]
