Fuel Pressure Reg. hose keeps bursting on OVS Tial RG

[flatlandsledder]

I purchased my friends 07 M8 OVS Tial. Last year the fuel regulator line leading up to the gauge on the handle bars kept bursting about 5 inches after leaving the fuel rail. I'm assuming the heat was the cause, but why didn't he have a problem with the other hoses that were right next to it ie.(boost line)? I am a newby and need to learn alot. Please bear with my ignorance.

Its the line that goes to the fuel pressure gauge? right use high pressure fuel line and it should be fine. That line doesn't even look like fuel line.

I have to agree with this. The line doesn't need to be large diameter, but needs to be able to hold up to a high amount of pressure. Looks like you are using a boost line for the reference on the fuel pressure. Boost is usually under 20psi. Fuel pressure is 30+

I did a search on the hose- Clippard urh1-0804

It said it was good up to 105 psig with a max temperture of 120F. But it doesn't feel like it should be used with gas. Seems like gas may eat at it. I think you guys just solved the mystery. Thanks

But just to be clear, the line should run from the fuel rail to the gauge, right?

For the fuel pressure gauge, yes as long as its reading the pressure after the pump and regulator thats what you want. make sure its capable of holding up to fuel and it will be fine. (Notice how fuel line is stiffer and usually has string inside of it.)

Correct, but don't confuse fuel injector line with normal fuel line. Normal fuel line cannot handle the pressures of the injection system. May cause to premature wear and ending up leaving you stranded. There's a few ways to tell the difference between the lines. Normal fuel line is soft, and has barely any strands for strength. It usually looks rough and is extremely black, when fuel is spilled on the line you can tell that it is "rough" . Fuel injection line has a lot more stranding and is hard to the touch. It is very smooth, and doesn't flex nearly as well as normal fuel line.

Here's my set up.

There is a fuel gauge right off the fuel pump to see what fuel pump pressure, and then the line goes into the regulator, and then there's my stainless braided line to go to my fuel rail pressure which is mounted on the console/control opposite of the key. My fuel return line is normal fuel line. you can see it directly to the left of the where the stainless line comes out of the T. It is "rough" but fuel injection line is smooth.

Hope this helps.

looking at your picture you are using boost line material insted of fuel line. Thats based on looking at your picture. also you I like to wrap all the lines with that plastic tubing to keep rubbing and heat off them (put some reflective heat tape on it once its done.

Go to NAPA

Ask For

Either

H10104 1/4 Size
H10105 5/16 size
H10106 3/8 Size


This is 350 PSI Burst! Really Great hose!!!

Can be used on Fuel, Trans Lines, Coolant!!

I would want it after the regulator so I knew the actual pressure going to the rail. I have used regular fuel line for gauges on NA sleds and never had a problem.

That would depend on the style of regulator but yes, you would want the fuel pressure reference on the same circuit as the rail.

Some regulators regulate fuel after the rail and run the return circuit back to the tank.

I cannot find high pressure line

I tried Napa and O'Riley Auto Parts. Niether had that small of diameter. Looks about like 1/8 inch. Smallest size Napa had was 1/4 inch. Napa did have regular gas line that would fit. I believe it was rated to 50 psi. I guess that would work. I'm gonna hold out for the fuel injection line for a bit more.

I would high preasure fuel line it will take the better then put loom over it

This is just a fuel pressure reference line to you pressure gauge?
Why does that look like it comes out the side of the stock fuel injector rail?

A couple options, if I am understanding this right would be to either change that barb on the fuel rail and gauge to something more common line 5/16ths. If that barb is in the stock fuel rail, I would cap it off altogether and just put a T fitting right after your fuel regulator and then run a normal size line back to your gauge.
1/4 is small and you would have a hell of a time finding what you need. I also used fuel injection hose from Napa but it isnt cheap.

The most important thing with owning a turbo sled is, clean, clean, clean.
I see a lot of dirt dust and grime in the compartment. This is what kills a turbo sled. Also flip the sled over and pull the belly pan off. Clean this area as well. If you spend one weekend you can get her looking good. You should go
over the sled thououghly every three rides. (belly pan off). I promise you
this is the difference from a sled that works, and a sled that runs flawless.

I just bought it

It's the previous owners dirt. I've already started the cleaning project.
