At what point is a FASS Fuel system benificial?

Just as the title reads, at what point is it beneficial to run a fass fuel or airdog system on your truck? How do you know how many gph you need?

I would say that it is always beneficial to run an upgraded fuel system...no matter where it comes from. As long as it is god quality.

Re: At what point is a FASS Fuel system benificial?

does FASS even make a fuel pump that can maintain 60-70psi?

Re: At what point is a FASS Fuel system benificial?

I beleive so.. I met the gentleman that owns the company a fuel weeks ago and he told me this.. (told me, didn't prove this)

On a related note.. the Fass has ports so you can put a heating element on the filters for cold weather conditions.

Does the Air Dog offer this? They don't answer e-mail very well

Fass do not seem to hold up well on power strokes. I would go a different route.

Re: At what point is a FASS Fuel system benificial?

The fass seem to be noisy and most of the ones on that I have seen have died at least once.
Maybe 6 or so, so I am sure there are plenty that are ok. But I only know of six and all have had pump failures.

You will also want to have some sort of under 5 micron filter beteen the pumps and inj...as close to the inj as possible.

I know fass have a stand alone pump that you can add iff needed, but no idea of durability.

Having said that they do a good job of getting the air out but personally I am looking at an airdog2, once there is more feedback on them.

Never, Fass does not make a complete system for a psd, They do have a few pumps /filter setups that could be used it assembling a complete fuel system

I always recomend a regulated return on all trucks, Superduty fuel pumps seem to hold up well to 400-450 hp

Mine didn't! Reaked havoc with my fueling.....
It was the worst pump that I have ever owned in all my year playing in the auto industry.

Might be great on a Dodge or a D-Max, but with a RR on a 7.3 they go to S&^% over time......it was the weakest link in my truck package.
