I've honestly seen more issues with FASS and AD pumps than I have seen with OEM lift pumps. And the nice thing about an OEM pump is they're easy to find in a pinch.
If I needed more fuel than the OEM pump would provide, I would use a pump/pumps from somebody who has been specializing in high performance fuel pumps for more than a decade and who isn't only focused on removing air from diesel fuel
That's exactly why the stock low pressure 6.4 pump in between the tank and our stock 6.0 pump sounds so nice.
Is there a thread about this or a writeup?
There is, but it's on the ORG. Shoot me a PM and I'll get you the link. I hate linking other forums within forums, you know?
We've been having great success with the current FASS high pressure pumps, but when you compare the size of the electric motor on the FASS Titanium Series (125G+) to the one on the competitor, you will see why the current FASS isn't having all the problems making pressure. The motor doesn't have to work nearly as hard when it's larger in size. FASS also didn't screw up the regulator design and try to make an adjustable with more O-rings to fail and leak and cause pressure issues. They had their problems in the past, but the current stuff is working great for us.
I quit selling the other a while back, wouldn't take any more calls from stranded customers.
I've been using a FASS pump on my vegistroke system (one of the originals) and I can't believe the punishment it has withstood. It's pushed thick, heated WVO @ 160+ degrees, at upwards of 95psi at times and never missed a beat. It's even sat off of the truck for over a year, soaked in used WVO, threw it back on and it worked just like new again. Amazing. I'm not exactly expecting it to last forever, but it's far exceeded anything I expected.
yea I havent had really any problems with my airdog 165 on my 6.4. Only time I had a problem is when it was -7 degees out my truck completly died on me going up the road all I did was take the filter off and put it back on and it maggically runs good again plus the motor is not making a nice noise. Ive had a ok experence with airdog but I wouldn't recommend them hopefully switch to aeromotive sometime soon.
Two different setups no? Are they set up the same for the 6.0 and 6.4? On the 6.4 you really only need to supply what, like 10-15psi to your HPFP? We need at least 55psi out of ours, so the pump is basically running at full duty sitting at idle.
My fuel system build ideas are constantly changing the more I read, but I'm thinking now it's going to be a sump, to a stock 6.4 low pressure fuel pump, feeding the stock 6.0 HFCM. If the stock 6.0 pump ever craps out a fuelab will go in it's place, but I'm going to try and keep this relatively simple. :clapping:
