Engine/Transmission (1994 - 1998) What's the altimate answer on fuel hose?

[CumminsPower98]

I have yet to find the best avaiable fuel hose for gas or diesel. I'm soooo tired of the JUNK sold at the parts houses. Gates for example is doing good to last a year in many cases (I used to mechanic for a rafting company and still do now and then when not on the road). I have tried the Gates transmission cooler hose that is high pressure and looks much better and it too cracks up pretty fast. I'm talking about gas applications mostly here but would also like to find what's the best for my truck. So far I have some Goodyear on my truck that seems to be doing pretty good. The OE hose on fuel injected cars seems to last forever. So where does a person get good hose that will last for many years with no worries of cracking and fire.



I see all this talk about the marine hose. Is this the answer? My local Napa sells some marine stuff, maybe I will see what they can get for hose.

I used marine grade fuel line on my truck when I replaced it a couple years ago.



IIRC there are two grades, A and B or something like that. The "A" looked like it was about twice as thick as the "B" and looked like it had a woven outer jacket.



The boat mechanic recommended I go with the "A", but unfortunatley he didn't have the size I needed in stock. I went with the "B" instead. Hasn't been long enough to tell if it is going to hold up for the duration.

My return line cracked with little notice. I didn't have time to order Larry's repair kit. I would have.



Used Gates Fuel Injection hose. It's Viton so it's good w/ biodiesel.

They stock the "A" grade hose, which is what I have on my truck. Very thick stuff with a special inner liner so the fuel doesnt touch any rubber parts. Still very pliable tho and makes great bends. #365 is the part number you want.

I read somewhere on 94's both the feed and return is 5/16ths, so that would make getting the kit from Larry's half pointless wouldn't it? Unless thats not true, anybody know for sure? I'd like to replace mine soon.

No, feed is 3/8" & return is 5/16" on a '94.

Thats good news! Thanks!

Sorry for kinda stealing the thread but I figured the question was already answered and I didn't want to make a new thread just for that.

 

[CumminsPower98]

Thanks guys, I guess I will try some of this Trident hose, looks like good stuff.

Is the Steel portion of the Return line 5/16? The part coming off of the pump that is.



I'll have mine run in Eaton/Aeroquip by the end of summer. -8 supply and -6 return.



So far my supply line is functioning nicely. I used -6 though and the oriphices in the fittings are too small. So that will be -8 and i'll reuse the -6 I have as my return line.

I'll also be installing a bulkhead in the tank for the return as the return currently comes into the pickup and aerates the supply fuel.

Kyle,



Please explain that to me. There is no air in the fuel system when it is working properly. So where is air coming from to aerate the supply fuel? If you don't use the stock fuel pick up basket you may have a problem caused by fuel sloshing. The basket restrains fuel at the pickup in order to avoid fuel sloshing from exposing the pickup to air when the fuel level is low and runs to one end of the tank or the other.

 

[biggy238]

The bulkhead will be for the return only. The current pickup will remain. Is that what you wanted? The reason I'll actually be doing this is the fact that the hole in my return line is in the last 6 inches or so of my return line. I don't have enough room to put an -AN adapter on the pickup quick connect lines. That is unless someone has another Idea.



Otherwise you are quite correct (as you already knew) if it functions correctly it won't cause problems. But then again, if the system functioned correctly, people wouldn't be replacing lines in the first place I suppose.



Happen to know the size of that steel return line on the pump?

 

[Joe G.]

If you need a place to connect the return line use the aux fuel tank line connection. You will still have to block the old return line connection or fuel will slosh out of it. I think some people have replaced the steel lines from the tank with good fuel hose. I will do that if my plastic lines to the fuel module go bad. I'm not sure where a bulkhead would go or what it would do to help the situation. The stock fuel module works ok. The problem is usually involved with the hoses. There is no fuel pressure there to amount to anything so clamp on hose connections will work fine.



Actually, I would like to know what you are doing because it may be something I would like to use. Thus the question because it is not obvious to me what you mean.

 

[biggy238]

It will be a short while before I can show you exactly what I mean. I have to get on top of this head gasket problem and then when the bed comes off to paint, I will show you what I have in mind.



It's been since the last discussion you and I had about my problem that I had actually thought all of it through and had it planned out.



One of my reasons for the bulkhead through the side/end of the tank was for cooling purposes. I had looked at the aux fuel tank fitting and there was a concern I had but I can't remember now what it was.



My return line had a considerable amount of pressure on it. I let go of it while it was disconnected and the truck was running and it got away from me easily.

 

[Joe G.]

There is a high rate of fuel flow in the return line, but I don't think there is much pressure. Has to be less than the pressure before the overflow valve. If there is then there may be a blockage somewhere. Kind of like a garden hose if you let go of it with the faucet on high. Flops around a lot.



The aux tank fitting just goes thru a hose to the bottom of the tank. If I remember correctly it exits outside the fuel pickup basket. There is not much room under the bed there so a hose connected to it rubs a little on a bed stiffener cross member. Not much pressure against the cross member so I don't think it will hurt anything. I have my bed tank hose hooked to it. So far from what I can see the contact does not amount to much.



I'll have to see the pictures or drawings of what you are doing, because I don't think a bulkhead/baffle will be affective for cooling at all. Anyway, I'm interested in your plan. The best way to replace the stock fuel lines setup that I have seen so far is just to replace the whole mess from the tank to the fuel heater and from the overflow valve to the tank. Mine is still good, but I don't expect that to last forever.

That's what i'm Working On
