At this point it seems iffy. They are on try 3 and it's still not right. I have V3 on my car and am legitimately concerned. I also don't want to keep paying to replace this thing.

I know it will not make anyone feel better, but after asking around. OEM high pressure fuel lines have also been known to fail when tracked.

Also, this problem is well known, and I at least know of two seperate entities that are working on a proper high pressure capable soft line with E85 compatibility.

I will leave them to introduce the product when they are ready. But I just wanted to give everyone a smidge of hope that this will be hopefully resolved soon. Why Full Race has not done this is interesting to say the least. Perhaps they need replaced often due to the pressure? Would be nice to hear from them directly.

Based on Full Race own advise, I am not going to change mine at this time. However, I am going to hold off on tracking until I source a fix. A fuel fire is a terrible thing, not risking it on track.
Got any links/info to people having OEM lines fail? Would love to follow along with that.

I would have to refer you to my tuner @Jester04
He is the person that advised me of this happening to cars that are used for track duty. But I have not personally known or read of this happening. But not everything is posted on the internet. He has alot more exposure to people then I.

Adding to this thread. I had my Full Race pump since 2024 and last year the line started leaking(was getting a high fuel scent in the cabin).

Was sent the revised line from the company I bought it from which would have been the V2. Today when I started the car it had to tumble a few times before it started and no surprise the fuel scent is there again. On Monday I would confirm if this second line is leaking also. Very annoying situation to say the least.

Would update you guys next week.

Can you confirm if your line had the p-clip so it could attach to the engine please. Thanks. Nevertheless, contact [email protected] and advise! We as a community need to tell the manufacture of our specific issues personally.

Hello everyone.
I’m all for safety and understand the concerns here. Please note that this line does not need a lot of torque. The factory line can handle being over torqued much better than the full race line. The torque is only 24ft lbs . 99% of people double or even triple that amount out of fear of leaking.
A common mistake acrossed the Automotive industry when using a crows foot on a torque wrench you should be 90° from the torque wrench. If you are not 90 degrees like the picture shown, it will increase the amount of torque on the component.
Having the crows foot in line with the torque wrench adds additional torque.
I know that almost no one actually uses a torque wrench. Please see the picture for the math equation when using a crows foot directly in line. I don’t remember the math for using it at a 45° angle but I know at a 90° angle It is the same as the value on the torque wrench.
I come from both Honda and the world of General Motors vehicles. The late model Chevy Camaro LT one is notorious for the factory line leaking went over tightened. These leak underneath the intake manifold and catch fire. A general motors also uses a ball and style connection.

I am not saying, someone installed something incorrectly here. I am simply pointing out a few things that could be helpful. If you are reusing the line, it is absolutely critical that it goes back in the exact position. The ball end after install has a depression line around it, and the cone ends do not end up with the same depression line. Over tightening will deform the ball end to the point that it will leak.
I am not saying there isn’t a plausible issue, but the vehicles that I’ve installed them on have had no issues even on the original version. Between my personal vehicle and four others, they have accumulated 70,000 miles since the pumps design. 3 of them exceed 700whp.
As far as the factory one breaking that happens because people put the factory line on the XDI pump and then try to bolt the line to the block. This bends it to the point of creating excessive side load stress. It was never meant to be installed that way on an aftermarket pump.

Please don’t think that I’m trying to say everyone is doing something wrong. I am only trying to help guide people to the correct method and help prevent issues. I take safety seriously. I hope the information provided above can help
