[willyslover]

as I understan it there are two systems , a lower HP unit and a High Horse Power unit. . who is using what



and what line sizes does the High HP unit use, and does it use steel braided lines and AN fittings ?



the site is a little weak as to descriptions.



Thanks Gary

I was not aware that there were 2 different ratings for HP with the FASS. The unit I have can push 125 gph of fuel and the supply line is a bright blue rubber line with 3/8 inch inside diameter. I drilled out the VP flair fitting that came with my unit to get rid of the restriction of 1/8 inch and allow it to have a 3/8 inch inlet at the VP. The fuel line is protected with a covering of the black wire loom cable cover and is tucked up out of the way against the top of the frame.

But if you look at the FASS's ability to be hooked up either an oil line, to use the oil as a heat source or the engine coolant line as a heat source, then the answer would be yes it does have a heating element.

I was under the impression that there was an electronic heating element built into the unit. Perhaps I misunderstood the conversation.



I also was not aware that there was two different systems.

With the ability of being able to push 125 gph, why would there be two HP levels offered. The most fuel (gallons per hour) that I have ever seen on my Road Relay at WOT is 4. 8 gph. I can put 400 hp to the ground. I know that the FASS was designed for heavy duty mining equipment, we are talking big dumps and earth movers that have engines that dwarf our 5. 9's. The FASS I have provides me with all the volume and pressure that the VP can handle, and thats the secret, it is a low pressure hi-volume supply pump that gets rid of air in the fuel and is a heck of allot more robust than the original lift pump ever thought about being. The VP is where your horse power originates. Keep the VP supplied with good stable fuel pressure and volume of flow and you end the worry of loosing it due to starvation. This was my primary reason for getting the FASS. The mileage improvement to 22. 78 is a nice side benefit for me.

Mundgyver thanks



does it use AN fittings ?



line size is relavent if you have very high HP and sudden demand [total volumne and pressure is fine, but sudden demand needs higher availability = line size]... and keeping low pressure and high volumne.



on a site that I looked at a while back they showed two size units , but no specs were listed.

There is a FASS available that requires replacing the stand pipe in the tank and also has bigger lines that is refered to as the high hp FASS.

This must be relatively new then. I spoke with Brad back in September and asked him about larger lines and replacing the stand pipe in the tank. At that time he said it was unnecessary.

 

[mcoleman]

It's also higher. I think it sells for 649. 00 but don't quote me on that.

 

[Mundgyver]

You could use an AN fitting but it come with barb fitting for everything but the VP fitting. The VP fitting is a restricted flair fitting which I drilled out to the inlet size of the flair fitting. The fitting that goes to this flair fitting from the hose is a barb to flair fitting. The kit come with the bigger hose clamp for the return lines but nothing for the fuel delivery lines. You will need to pick up 1/2 dozen 1/2 inch hose clamps. It is a very well though out system. I am very happy with it. I hope to get some pictures posted this week by Friday.

FASS website??

I am VERY interested in the Fass system. One problem though. If the pump goes out - where do you get a replacement? I have asked Piers and they did not know. Does anyone have a contact with "Brad" to see if their is a replacement or aftermarket pump that would work. I would hate to buy this near $600 system with no options for parts replacement. Who makes this system and will they be around in the future for replacement parts. . ?? Anybody have any information.



Thanks.

clw1100,

I have asked the same question with out an answer as of yet. Although it is stated that the FASS system should last for 500,000 miles plus, that does not help if you break somethimg while off road or even if something on the road was to hit the system and damage it. Where can you get replacement parts and filters, with out having to order via the mail, and wait for days or weeks without a truck. Any thing made by man and put into my hands can be broken.

Even though I have these concerns on my mind, I will be ordering one this week and hope to be finished with the lift pump problems I've had in the past.

Replacement parts can be purcahsed through Brad. When I asked about replacing the pump the cost was around $300 or maybe just a touch less.

 

[clw1100]

Great, BUT...

Who is Brad? What is the company name or phone #? Website?



Thanks for your reply. Please dont think I am being a butt about this, but $600 is a lot on $$ for me.



clw1100.

Sorry Brad is gentleman from Diesel Performance Products that is selling the FASS. He is also a TDR member. As far as a website they do have one, but I cannot find it right now.

Go to www.Google.com search on "fass fuel system", then take your pick.

I couldn't find the manufactures site while searching through Google. Here is the link:

Is there a specific part # FASS pump that I need to order, I'm running about 360 RW/HP max, I think, or there abouts With present mods. I dont run around on level 5 much but I do like level 3 sub level 5 as a daily driver. Edge Comp & DD stage 1's and other stuff.

Of course there are a set of DD stage 3's waiting to get in there as soon as I find the money.

Thanks, TJ

The FASS Model that I bought was a FASS-150-DO-98-02. If you have a short bed there is a different mounting bracket than for the long bed. As far as your mods and concerns with the pump being able to keep up, I would not worry. This thing could supply 1000 hp easy.

Okay, I've seen all the "entrained water theory" explanations. I want dyno numbers from one of our trucks to back that up.



Now the other question is what makes this electric pump so special?



Have we (as a group) not since 1998. 5 been searching high and low for an electric pump that would last longer in our application? Forget the other features, why is this electric pump going to outlast the Carters and whatnot that we have been trying to make work?
