the old man has been bugging me all day about this!! ( fuel lines/heat/headers )

[F 150Cobra]

he says that the fuel line is too close to the headers and its unsafe!.. i think its just fine but i still wanna put some kind of heat cover around that part...

the distance is 5 inch


dont worry about the dripping fuel look on the regulator.. thats old.. it doesnt leak anymore

nway what do you think????
btw i still have to bend it to make it nicer looking now its just sitting there


the old man wants to insure me tomorrow so if something happens he well be fixed haha!

Id do it so it dont vapor lock on ya.

 

[countryboytn]

Hey man, might wanna get that gas leak fixed...

 

[Skandocious]

I was going to suggest wrapping the headers but it would probably be easiest to do that by taking them off and I'm guessing you don't want to do that... I suppose you could wrap the fuel line but it makes more sense to wrap the heat source.

You could put a heat shield bolted to the frame to dissipate the heat. Doesn't have to be anything fancy, just something to get between the headers and the fuel line. Personally, though, I wouldn't get too excited, as that is a pretty fair distance away. The factory routes it inside the frame rail right past there. You could put a little pipe insulation around the fuel line if you are concerned about vapor lock, solves the problem quite nicely.( Been there, done that.)

I wouldn't say it's too close!!!

Looks fine to me!!!

 

[flareside_thunder]

Looks good on the distance but vapor lock would be my concern.....even then it still looks good...I'm just picky enough to wanna insulate it anyways.

 

[smokey]

Looks Ok to me distance wise.
I would put a few hold down clamps on the line so it doesn't vibrate and loosen the fittings or rub a hole in the line.

Looks ok to me, but you might want to insulate it anyway. Just a little added insurance so you don't have to worry

Get some header wrap. Will help with that problem and will help your under hood temps too, less heat under the hood, the less heat you draw in the intake, colder air is denser and as we know denser air is more power...

 

[F 150Cobra]

thanks!! i will put a few clamps in there and insulate it with something!

 

[m78]

I agree on insulating the headers. Seems everybody has problems with their starter if They're not insulated

 

[Truckin4life]

Luckily i havent... Yet, hope you dont jinx it!
I have noticed on long drives my feet get raging hot...

I've heard bad things about header wraps.. word was that they'll rust your headers out buy holding moisture when the engines shut off.

I'll try and find the post.

I would advise using caution with the heatshield wrap on the downpipe. I wrapped the PS header on my Blazer with it to try and keep from frying the starter. It held moisture and rotted the header. Had to buy another pair of headers just to get the passenger side one.

Anyone need a drivers side Hooker header for a 74 Blazer with 350?

I thought the same thing - and no doubt any residual water gets baked out quickly when it's running. But all the same, I've seen wrapped portions of exhaust come off vehicles that showed notably more corrosion than unwrapped portions further back.

Could be the corrosion starts when things are cold. Then as the rust proceeds towards the flaking point, the hot/cold cycles accelerate the flaking & expose new metal to corrosion faster.

I also saw a wrapped - very nice/expensive, custom 304 stainless downpipe (from a 2.0 Mistu turbo engine that occasionally saw EGT's to 1700F - knowing the guy, maybe even higher) accidentally dropped onto a concrete floor. A couple places in the tubing cracked, almost as if the material was crystalized & shattered upon hitting the floor. That situation drove the maker of the downpipe to begin putting a disclaimer on the product that they couldn't stand behind the product if installed with header wrap.

Since I intend to wrap my crossover, I'm betting my 6.5 would melt something internal well before getting the exhaust hot enough to impact the crossover's metallurgy.

I too have seen header wrap rot out pipes faster than having nothing there. You can evaporate the moisture out, but it will get wet again and again and not shed as well as a plain pipe. It also holds the salt in.
Didn't I read somewhere heat wraps on exhaust isn't legal for street use?

Lost my high $$$ ceramic coated crossover this way, now I just have unwrapped steel x over, mine was a daily driver also, I put 2 cans of hi-temp paint on the wrap also hoping to seal out the moisture, to no avail, rotten to the core in less than 3 years, I was advised to not wrap by a few, but I figured by sealing with hi-temp paint it would not rot I was wrong.

I think it will be fine. If you want some cheap insulation for the line, you can try to find some of the stuff that was used on EGR tubes. I have it on my Ranger because I have nylon lines about 3" from the exhaust, but I haven't had it long enough to know how well it works. A small sheet metal shield would work well also.

You should be safe but to prevent vapour lock id consiter putting some sort of heat sheath over the fuel line. On my Powerstroke there is about 5" of space between the exhuast manafold and fuel lines... and i have seen the exhaust gas temp guage at over 2300deg, no problems at all.
