Fuel line kink, Under the tank Options

[trojanhorsepower]

Hi All,
Strange question. The rubber fuel lines that come out from under the tank both are kinking right where they leave the tank nipples. I cut them down as short as I can. It still kinked. Its like the nipple is too long, or the tuning is not strong enough. It came from tangerine racing. It gets nasty black all over me if it gets fuel on it. Kind of weird fuel lines would not be ok around fuel....

Thanks,

Peter

If you put a loop in it it should not kink. Check out iankarr's vid on installing SS lines he goes over this.

Yeah, I thought that was how I had it originally. I will get some more hose and redo it.

Thanks

Make sure you get quality tubing, preferably high pressure, often sold as "fuel injection" hose.

I had an issue with Tangerine Racing tubes as well. The issue was the bend at the gas tank was not enough to allow room for the hoses to connect. I had to further bend them to allow room for the hose connections.

Here's the initial install. The pipes point right to the front wall.



So I further bent the tubes to give more clearance.



Now they fit better and I could easily get the hoses over the tubes. It doesn't look much different in the pictures but the fit was much better.



I opted to not connect the lines directly to the gas tank as I didn't like being under the car making connections and especially if the tank needed to be lifted for any reason then trying to disconnect the tank. I even welded closed the round access hole.

The hoses are routed to the driver side where I mounted the fuel pump.



The hoses do not kink and the extra hoses allowed me to do all the connections above the car and if the tank needs to be pulled, just lift the tank. I can still run the engine with the tank lifted. Also allowed me to check for leaks once all the hoses were connected.

OK thanks for all the responses. I will pull the tank out and try new line and try to add some bend to the SS.

Ian sent me a note that some fuel hose I sent him was giving off black residue when wet with gas so I took a sample of the hose I had in stock and left it in a jar of gas for a month. It didn't let off any residue, but its possible that the previous spool of hose from Gates had an issue.

Hi Chris,
I purchased my kit a while back so you probably don't have that batch anymore. The first picture is with just a few drops of gas. The second is after pulling the lines off the tank.



The line seems fine once it dries just seems to kink easily. Ill see if the Napa stuff is usable.

I just redid all my lines with -6 AN fittings and I use steel fabricated lines from the auto parts store I made sure I had plenty of loops in the piping to avoid kinking. All works well so far.

All the modern FI hose kinks easily. I have a spring overlay to prevent kinking of the 9.5mm id stuff but nothing for the 8mm.

I used wire loom around the gas line under the tank to prevent it from kinking. Wrap it around the line and use tie wraps to keep it from coming off. Similar to the spring idea. I got it at the local Ace hardware store. Something similar to this. https://www.cabletiesandmore.com/black-wire...NgaAixCEALw_wcB
