Just ordered my regulated return and was looking at the pre pump/intake kit... Who has done it? Whats the difference between the brass fittings and stainless steel fittings? Pros Cons?

Re: Pre pump/in take modifitcation... who's done it
I've done both mods to both powerstrokes. /ubbthreads/images/graemlins/smokin.gif
Which fittings are offered with the option of stainless or brass?

I'm assumeing you mean In-Tank.. Not In'take ??? I've done both. The only difference between Brass & Stanless is.. Corrosion issues. I went with Brass 100K ago and NO probs.

Re: Pre pump/in take modifitcation... who's done it
The brass fitting shown is a double compression fitting. You use it to connect a short section of steel tubing to the OEM pickup tube. This short section is then used to bypass the check valve (duck bill) in the stem of the black rubber pickup foot. I don't think it matters a whole heck of a lot which material you use. Brass and steel together form a galvanic circuit, but should outlast the rest of the truck. Stainless should last even longer. If you plan on keeping a lot of water in your tank, go with the stainless. /ubbthreads/images/graemlins/rolleyes.gif
I used the ITP in-tank kit, which I don't believe is available any longer. I think it uses stainless tubing and brass fittings. /ubbthreads/images/graemlins/shrug.gif

Re: Pre pump/in take modifitcation... who's done it
Lots of people have done it, the in tank mod. If you do that mod in combination with the regulated return you really do need a good, very good pre-pump filter and water separator. Putting the regulated return on the system routes almost all the fuel through the heads instead of almost all of the fuel going to the return before it goes to the heads. Two things happen, the fuel overall is heated up and the fuel flow through the stock 2 micron fuel filter is much greater. The stock fuel filter is still a good filter at that flow rate, but I don't think that it is a good water separator. It is a crappy water separator in the first place almost useless as a water seperator at those higher flow rates. I have a Dahl 100 pre-pump filter with a 2 micron element that is an excellent water separator at that flow rate also. These mods were the forum major topic in 2001 & 2002 so most of those with those early models have already done the mods. IMO the mods are good ones, just need to do all of them. Or, just the tank mods with a pre-pump filter. I went with the in-tank mods, or "Hutch" mod, then the Dahl, then the regulated return, then a cooler for my return fuel line. Brass vs stainless, well that also was a topic of disagreement a few years ago, mostly about the brass ferrule not gripping on the stainless tubing. Bunk, I have both. Stainless on the suction side and brass on the return extension, both are tight four years later, I dropped my tank to clean it recently, so I don't think it really makes any difference on the fittings. One thing that you should not do, IMO, if you fabricated your own return extension in tank is use a brake line. They are ususlly a galvanized coated tube, diesel fuel releases the zinc into solution and that is not good for injectors, some made that mistake when these mods were the new thing a few years ago. Me since I was bypassing my SS fuel line to the pump for the Dahl line I just used a section of the stock exterior fuel line inside my tank for an extension. Sounds like you will be having some fun with it. Good luck, 106

Only one, when you install the pre-pump filter and get rid of the pushlock fittings on the suction side of the tank and fuel pump I would use 30R9 hose if you intend to use any bio-diesel fuel. Other wise if you intend on using straight diesel fuel 30R7 fuel hose. Price difference is 30R7 is around 1.25 per foot and 30R9 is 4.25 per foot and harder to get. I mix it up, I have 30R9 3/8" hose from the tank to the Dahl pre-pump filter, then use 5/16" 30R7 hose, it's only about 3 feet long, from the Dahl to the fuel pump. I change my Dahl filter element every 20K or 1 year so I just replace the 3" piece of 30R7 hose when I do that. The tank to Dahl section is much harder to work with so I have only replaced that section once, when I went to the 30R9 hose to run bio occasionally. 106

Actually, the AIRDOG would be a good choice for you. When you use an AIRDOG, you don't need to do the in-tank and pre-pump mods.
Also, I thought I had seen that the airdogs were back in the $700 range again. I just checked ITP's site and couldn't find them, so I'm not sure. /ubbthreads/images/graemlins/shrug.gif Perhaps one of our courteous and helpful sponsors will chime in to announce their decision to vend AIRDOGS, and hint at the new, low, low price! /ubbthreads/images/graemlins/smile.gif /ubbthreads/images/graemlins/confused.gif /ubbthreads/images/graemlins/rolleyes.gif
/ubbthreads/images/graemlins/wink.gif
I did the in-tank mods in addition to the AIRDOG for a belt-and-suspenders approach. I was going to drop my tank anyhow to do the harpoon mod, so why not spend a little time and $40 to do the in-tank mods too? I figured I'd rather let the airdog handle the entrained air, and avoid the huge gulps of air altogether via the in-tank stuff, even though the airdog is supposed to be capable of handling both.

I spoke with Dennis recently and he is working on his in-tank and prepump kit, making a few changes to it with some new components... hopefully it will be available again soon. When I spoke with him a few weeks back he said hopefully a month or so. /ubbthreads/images/graemlins/warmsmile.gif
