Will Fuel Tubing melt going to carbuerator? Touching engine head.

[redhatman]

Hey, I got my rc car back today.. nice. They put in a brand new engine. I noticed that the fuel tubing is touching the engine head. Will it melt it or cause any problems? I attatched some pics. Thanks

you should be ok but if you are to worried about it tie it back with a zip tie or something..

 

[redhatman]

tie it to where? do you mean put a zip tie on the fuel tubing, just not tight?

 

[beason]

youshould be fine.. you could but a bit longer peice on there and wrap the zip around it and something else (that doesn't move) to pull it just enough so it doesn't touch

 

[redhatman]

ok, but what could I hook the zip tie to? Thanks a lot.

Traxxas makes a heat shield that slips over the fuel line where it may touch the head. It came stock on the older T-Maxx. If I remember, it was yellow.

Looking at the picture, you can swivel the intake nipple so the fuel line goes on the other side of the carb. Just keep an eye out the the fuel line doesn't get caught up in the linkage when the fuel filter is installed.

The other option is to run the fuel line around the other side of the engine and swivel the intake nipple to the rear. IMO this will be better. You will have a longer fuel line to help it run longer while its on its back.

Looking at the picture again you should also lengthen the pressure line to the pipe. Its up for debate but I would say a minimum of 6 inches would be a good place to start.

 

[redhatman]

ok, ... thanks. I will take all of yours into consideration.

My fuel line slack is wrapped around the engine head. I have never had it melt before.

 

[aj200415]

it wont hurt the fuel line, but dont let it touch the flywheel. it will burn it in half. i have done it.

I always put my fuel tubing AROUND the airfilter.

This way it doesn't touch anything.

It's a little blurry, but here's how my GT is setup... Note; it's the same exact engine, but I've got the O'Donnell head on it (trust me, upgrade the head - it makes a TON of difference)...

 

[redhatman]

yea, i was thinking about upgrading the head. whats a good one, and how much does it cost? Thanks

The O'Donnel CV.12 head works great - It's what I have on mine, and it literally changes it's performance - You won't even recognize your engine, lol. It sells for around $35 or so. I don't have the part number handy at the moment...

Here's the link for a simular head (blue):

They also have red; just click on "Possible Substitutions".

And believe it or not; Hardcore Racing has a head on there, and it's CHEAPER than OS's.... :spit: It's listed here, about half-way down;

Stay away from anything marked "CV-R"; they won't fit the CV.12.

Mine takes a different plug tho; the McCoy MC-59 plug (mccoy, dynamite or ofna, they're the same length). Otherwise, I love it - Much more cooling area, allows me to run the needle about a half-turn leaner and not worry about overheating, and the blue matches the chassis (for that style factor).

Just make sure you use a good quality allen wrench when replacing the head, and tighten in a star pattern (like your tires on your 1:1).

 

[redhatman]

ok, .. thanks a lot heartbreak. I would need to make sure that my glow ignither fits into one before I buy it. I do not want to have to buy a new one.

 

[HeartBreak]

If it's a standard length glow ignitor, it'll fit with plenty of room... Mine is about 2 and 1/4 inches from "hilt" to tip, and it fits in the head with enough room for my fingers to easily clear the head.

 

[redhatman]

I have this one right here: http://www.rcuniverse.com/magazine/article_display.cfm?article_id=497 will that work?

the fuel tubing touching the head should be fine although you should keep an eye on it for abnormal wear from rubbing. You can split another piece of tubing and put over it to shield it. But My advice would be to install a good fuel filter on it and put a longer section of tubing on it so you can mount the filter. Mine is ran in front of the air filter, through the shock tower, to a filter between the shock tower and the carb, then to the carb. I have a wire tie holding the tube right at the filter on the shock tower. Just make sure it stays clear of the servo linkage.
