I wouldn't waste 34 bucks on fuel line. I am using regular half inch fuel line purchased at NAPA for just over a buck-a-foot. These higher pressure lines that are being mentioned are overkill for 15 to 20 pounds of pressure. I replaced my banjo's and bolts completely with the same items ROD at WILDCAT uses in their high flow system. I am using half inch regular fuel line all the way to the VP44. If you want some additional info, pm me.

Another good line in any size you want is Synflex air line for big trucks. It is a few cents a foot and is teflon lined, nylon outside, uses compresson fittings. Is SAE approved for 150 pounds. Trucks use to for fuel, air, water, whatever. A lot of big trucks, mine had it, use the teflon line for the gages right into the dash. The stuff is used for the roadranger shift lines also.

A compression fitting is a fitting that alows you to connect
the stainless steel braided line to the metal fuel line. They
are also called "hard line adapters" or "hard tube adapters".
On page 53 of the Jan.-Feb 04' Summit Catalog there is a
picture of one. Here is the part number if you don't have
a Summit Catalog: #RUS-639220 (-8AN female to 1/2"
line). They also make them for -6 line too.

I disagree with you on the fuel line; (rubber vs. stainless steel
braided). I have personally had trouble with that rubber fuel
line leaking on occasion and know other CTD owners who have
had the same problems. Those fuel lines are under the truck
and exposed to "all the elements" on a constant basis. The
stainless steel braided line is TOUGH and is not going to give
you any problems. Heck,.....that is all they use on fighter
aircraft as well as civilian airliners. I also go off-road" with my
truck on occasion so I don't want to worry about that either.
So,.....IMO, $34.00 is "not a waste" as you put it. Everyone
knows that even the stock fuel system on the 24 valve engines
is barely adequate and when it fails you are "down in the water";
I know because it has happened to me!!

I guess each DTR Member can decide what is best for them.

Personally, I would want to use all solid line. I am more experienced with it as compared to the braided. If I ever get to working on the fuel system that is what I will use.

How bout some 1/2" schedule 40 PVC? It's cheap. It's strong. It flows. It's very easy to fix. Solve's everyone's problem. Now, I wonder if it's rated for diesel? Maybe galvanized water pipe?

Perk,

be careful running all solid on the truck. You need at least a section of flexible line to absorb vibration and allow for engine movement.

I personally think the SS braid is the best way to go for peace of mind. The line and the fittings may be a little overkill, but you'll have no worries about a line rupture, tearing, or rotting. Aeroquip also makes a cheaper nylon braid if the SS braid is too expensive.

Are you trying to start trouble in here???

Banshee,

I hadn't thought of the effects of vibration. In light of that I might use a little SS braided.

Who? Me? Never.

Thats on an AN fitting for the FASS unit.

I personally will probably do some solid line myself unless the cost is similiar to the braid, which I am not sure of. I misunderstood you John about the kind of fuel line you were referring to. I thought you were talking about either the single or multi-strand hydrolic hose, which apparently you were not. I stand corrected. Can someone tell me what kind of fitting goes into the tank & is it removeable? How much is say a 10 ft piece of steel braid 1/2 inch line?

Hi all,
I think I get the theory here. Relay pumping so the injector pump has a positive feed and the injector pump doesn't work as hard (read longevity).
Why aren't we using stainless tubing inside the frame rails?
Do you have to drop the fuel tank to perform this upgrade.
Has anyone looked at the Mallory gas fuel pumps? 110gph. I've used them on other toys.

Thanks for your reply.

About your question on fittings to the tank. Both my son and
I did this and I can tell you without a doubt that it is a PITA!
We initially used the copper/brass -8 fuel tank pickup that
comes with the Van Haisley Auxiliary Fuel "Pusher" System.
We put the fitting in the exact same location as the stock
"pickup"; that being; inside the stock plastic "anti-slosh"
canister or "BOMB" as I call it!! Anyway, that pickup
was TOO SHORT and we had bad cavitation problems!!
So, my son (banshee) custom designed an aluminum -8
pickup with a "flared" end that was alot longer and we
ran this "pickup" down through the stock plastic Dodge
"anti-slosh" canister all the way to the bottom of the tank.
So far, I have had no problems with this system, but IMO,
unless you are WAY UP in H.P. etc, I personally think it
is "overkill" and a waste of your time and money!! We
have some friends that are just running the -8 line by
"tapping into the stock fuel line" at or near the fuel tank
and they hold pressures just as good as I do! Now, I have
seen a few Dodge CTD's that have drilled another complete
hole, away from the stock pickup and then use that instead
of the stock set-up or run that "parallel" with the stock system
to actually have two separate fuel systems. I think Jim Fulmer
has done this on his 12 valve truck and I know Van Haisley
has had good luck on his trucks with this too.

Hope this has helped you some.

Cyborrg:

I know that the Mallory 4140 and 4140M Fuel Pusher Pumps
have been tried by alot of Dodge CTD Diesels owners and they
have not held up very well. I know that Doug Smith (Jetpilot)
had one on his 2001 Dodge CTD "Black Rocket" and I don't
think it even lasted three months!! At $239.95 and $249.95
each that is alot of expense for something that won't last
very long! Also, FYI, both my son and I have both tried the
Product Engineering PE 4200 Pumps (270 GPH @ 18-22lbs.)
and neither of them lasted for more than four months either!!
They are about $300.00 too!!

FWIW,......I am going to stick with these Holley Fuel Pumps
for now!! Mine has been on the truck for almost five months
now with no problems so far!! I bought it on sale at "Advanced
Auto" for $88.00!! Heck, I figure I can buy almost four of them
for what I paid for the PE pump!!

Take care and good luck to you guys on these fuel systems!!
