Fuel line fitting, not the olive or nut

Hey guys,
So while I've been poking along with the tdi swap I've replaced the fuel line with gorilla hose by Goodyear. It's MSHA approved and works with bio. We use it on our equipment underground at the mine and currently run 50/50 bio no issues.

So I can find the compression fitting nut and olive just fine. But does anyone know what the male end is or if it is available. I wanted to get hoses made with that barb fitting to keep it all the same but can't seem to find it.

Hose clamps are the backup idea and will work fine. Just sounds cooler this way.

Thanks,
Pete

Personnally, I prefer hose clamps for the convenience of repairs while remote travel or in field. You can keep a spare section of hose for the unknown, and more easily source replacement in a pinch.

Just a thought.

Roger that. The guy at delta rubber wasn't sure what that fitting was and didn't think he could get it. It's one of those things that shouldn't be that hard to find but is.

What is the thread size?

You may have better luck with a UK vendor.

Size suggestion...

The standard size on most LR filters is 14mm X 1.5.
There are cases where some of the fuel pump fittings are 1/2" X 20 UNF thread which is close enough to a male flare fitting that they interchange.

The easiest way to check this is to get a 14mm X 1.5 bolt which is more common than the other size and if it screws into the female opening, you know what to order. You could also locate the less common 1/2" X 20 UNF thread bolt to double check when/if the 14mm X 1.5 bolt does not fit, but most likely it will be 14mm X 1.5.

How do you plan to handle the banjo fittings?
If they get am overcrimp and distort, you'll have a leak to contend with.

Hope this helps.

Robert thanks for the information. I will look into those and see what I got. Good to know what I'm dealing with though.

Haha yea that is a good point. Well this is the first step of getting rid of the rubber feed and return parts. I have the new stock plastic lines with the banjo fittings to go from the filter to the injection pump and lift pump to filter. And I thought I have heard those are holding up. I'm not really sure what to do for a replacement. Maybe some fancy SS braided ones that I can get the banjo fittings pressed into.

Thanks!
Pete

Generic filter head???

We use a universal filter head that looks like this picture (only larger haha).

They run about $40, but have an inlet and outlet on each side as well a top fitting.
We have the proper plugs with sealing washer that would let you get rid of the banjo fitting altogether if this will help.

It takes the 16mm X 1.5 spin-on so uses the stock OEM style filter, which BTW is still the most common spin-on fuel filter used worldwide.
I have about 3 or 4 pages of cross over numbers.

Interesting stuff

To follow through the fuel line.....what are the thread sizes for the banjo bolts in the injection pump and the inline flare connector to the return hose?

Cheers

Gorilla hose by Goodyear...

Hey Pete:
About that Gorilla hose by Goodyear... which I think is made of Buna-N (nitrile) rubber.
Am no expert, but supposedly compatibility depends on the kind of veg and the kind of rubber. Soy and peanut are OK with Buna-N (nitrile). Canola (rapeseed), biodiesel and corn are not OK. Here is a site I found where you can check many chemicals and many materials compatibility:

http://www.coleparmer.com/techinfo/chemcomp.asp

It will take a while for fuel line to dissolve, but when/if it does, it will go a long way to clog up the fuel system.
We had this happen years ago on a Mercedes 300TD wagon and it was a bitch to diagnose.
I only use Viton hose with veg which is very expensive and sometimes hard to locate in long contiguous runs, but a lot safer.

Hope this helps.

I went with nylon like the factory. McMaster has it in black and clear (I used clear). Pretty much immune to anything but heat.

Bronco, IF you end up hanging your filter head off thr edge of the edge of the front right fender, as is factory & typical, you need to run a 1/2" wide support bar down to the inside of the wheel fender well for support (very close to the filter). The diesel vibration requires it, other wise the flexing of the fender (from vibration) will cause the fender edge to fail and the filter & head will flop off. In my LR factory re-power kit this, "extra piece" drove me crazy trying to figure out where it went as there was no directions for it .... finally spotted it's location in one of the photos.

Hey guys thanks for all the responses! I am in Boulder/Golden this weekend for a mining competition. Yea that's a good point the gorilla hose. Maybe the hose guy doesn't know for sure. But I'm pretty sure we use it at the mine. But yea I will look more into it. I like that filter mount and make your own fittings. And that bracket is a smart idea. Thanks again and I will look at these more when I'm back and not operating on a crackberry phone.

So I ordered a couple brake line fittings with the above sizes and they both were a no go.
It appears they are about a 12mm and the thread pitches that fit ok were the 1.0, 24, and 27. But looking at the UK forums it sounds like m12x1.0 is not the size. But I might give it a shot anyways.

I had my doubts about that gorilla hose a bit. I might just go and get that viton and have them remake them.

But yea looking like hose clamps it may be. I wonder whoever is making those new SS hoses for suppliers and where they got he fittings.
