Hey all, I'm looking to put a fuel system on my 2001 24-valve. I have been looking at both the F.A.S.S. 150/150 system and the GDP Fuel BOSS mechanical system. I don't really know what one is better for where I'm headed with this truck. It's fairly stock right now. But things are going to change. I have guages and a hypertech prgm. for now. Going to be running a Smarty stacked with an Edge Drag Comp or a TST, Not sure which one yet. But wanting to know what fuel system is better to go with for my application. Thanks heavy J

 

FASS is great, one of those "do it once" pieces real good quality too.

 

I've seen the FASS 150 - looks like something you'd use in an airplane... what's a GDP Fuel Boss?

 

It's a mimic of Opies MITUSA pump, mechanical belt driven of the crank

 

Go with a FASS they provide enough fuel and are very reliable. Easy to install too

 

I had a 150 FASS on my truck, worked great. Love the extra filtering, easier than the stock unit. Whats the fuel boss worth? You could also look into a cam with the fuel pump lobe on it and run a mech pump from a 12v. Might be in the same price range, although more labour intensive.

 

The only thing with the fuel boss is that there is no suck down at WOT because it's rpm dependant. I've heard with heavy fueling programers and an electric pump you can really suck them down at WOT. Is there any truth to this?

 

yes but the FASS 150, is ment for trucks over 600 hp. this thing is ment for preformance i got one and love it. ull need to get a new draw straw, that will be ur hardest part of the install.

 

I had the 150 running out of the stock draw straw for just about a year and a half, never a problem.

 

Yes its typical for fp to drop at wot. Bigger lines and fittings can help alleviate the problem even with a stock pump. Even at 490 hp a stock pump and a line kit from vulcan performance kept fp above 12. All the mechanical setups I'm familiar with increase fp with rpms thus eliminating the fp from being sucked down. Its not really going to be a performance issue, but I went mechanical for reliabilities sake.

 

I should be getting the fuel boss when UPS comes in today. When I ordered it last week, talked to Richard at GDP, essential advantages are that pressure increases as RPM increases, and with some later model trucks (mine) the molded in 'draw straw' sometimes keeps you from getting the last 1/4 to 1/8 th out of you tank (if you put another straw in-because you can't get as low as the stock one). So what the set up is going to be is another straw in the tank with another fuel line to the mech. pump, but when that starts to suck air, the origonal pump will still pump fuel into system, I'll be able to get all the fuel. (interestingly, Richard said that with electric pump with recycling excess fuel to tank, that the last 1/8th tank makes that fuel hot-I guess there is a lot of heat removed from CP3 and other parts from the fuel circulating). Anyway at the GDP site http://www.glacierdieselpower.com/
there are some illistrations and install instructions make probably better explanations than me!
There is a 2 yr. warranty for fuel boss, but the thing is supposed to practically last forever easily 200,000 miles, and it seems well made-I'll post about it when I get it.
It flows something like 110 gal/hour at the 'stock' setup, but replace a spring, and you'll get something like 130-140 if I remember right. That info is on the site too.
I'm getting twins soon (Nathan's twins) so I wanted something that would flow enough fuel for them, this is supposed to be able to do the trick

 

good deal guys thanx for the input it is really helping me out in what to look for.

 

got it yesterday. It DOES look well made and simple (simple is good in mind) It comes with big bag of fittings, lotta hose, a bypass valve and other stuff. The picts came out a little blurry, but you can see that the main body (blue) is cast iron, shaft is steel, and mounting pad is machined aluminum. Very pretty! I understand they have rebuild kits if it ever needs one. I like it so far.
