Flame Arrestor for Edelbrock 1409

[Jfreeman1412]

Hey Guys I just changed the carb on a 73 318 to a 1409 (thanks to the info on this Forum...Thanks)but my flame arrestor dose not fit now. I See that some are retrofitting but i am not sure mine is tall enough. Any one know anything about it? Or where to pick up a couple for a good price? Thanks.

What carb did you have before?

 

[Jfreeman1412]

I think it was a Carter. The Boat is a 1973 F30 with twin 318's

Looks alot like this one.

They have several different sizes. Measure the flange diameter that the arrestor sits on.

Being a cheapskate, I used the flame arrestor from the Carter AFB that I replaced. Had to increase the opening size a tad; an easy fix with tin snips & a file...

Me too! Had to grind on it a bit with a pencil grinder, but the little darlings fit just fine.

PS: Are we related?

I would like to be a cheapskate, but i have this kind of Flame Arrestor.
Do I have any options.

If it doesn't fit, try to make it fit. If you can't make it fit, then you need a new one.

Does the bottom opening fit the 1409? If not, can you enlarge it? If so, you can use it.

Five minutes with a pencil grinder and that old Carter AFB arrestor fiits the 1409 just fne.

Man, I don't see how you did it with a pencil grinder Mine wouldn't even come close to taking that much metal off. I had to increase my diameter about an inch. Took it to a local marine mech and he let me use his air die grinder that had a carbide grinding bit like this http://www.langtoninfo.com/showitem_imagedetail.aspx?isbn=B003A6C42S...

Still took a bit of grinding... I wouldn't even attempt with a pencil grinder.

 

[fastjeff]

Ooops! I also used a carbide bit. Didn't mean to confuse the issue. (Those grinding stones are useless.)

Congrats on getting it done.

Hey guys what we ended up doing is using about 2-3 inches of 5 or 6 inch Heat ducting to raise it up and it worked great. The 1409 comes with an long rod anyways and it fit perfect. I will post pics when i get back out to the boat.

 

[Jfreeman1412]

I found a half way decent pic of it.

Clever

I would double clamp that fuel line to copper tube line next time I changed fuel filters if I were you. Better than that get a barbed nipple at carb fitting. Here is a compression fitting set up that could be used I guess (not sure coast guard approved for marine) http://www.jegs.com/p/Edelbrock/Edelbrock-Universal-Fuel-Line-Kit/743631/10002/-1

Or this one...http://www.ebay.com/itm/Edelbrock-C...CI%2BUA%2BFICS&otn=21&pmod=330745382846&ps=54


Don't want fuel leaks below deck

 

[Jfreeman1412]

Good Call Thanks! That is the way I bought the boat....But I am always up for a good suggestion!

 

[Jfreeman1412]

Here's a better picture!

 

[fastjeff]

Agreed on double clamping that copper tube/ rubber hose connection. I use the same filters on mine--with double clamps--and it makes them a breeze to change.

Remove the heating duct and see if that has an affect on your rpm problem. Seeing those stacks on a stock engine don't give me a warm fuzzy feeling.

I will give it a shot, but it the same on the other engine and it runs great! Thanks for the suggestion.

Yeah, I thought about that after I said it. If the other engine is running good with the stack, then it shouldn't be the issue. But, you should consider all of the changes you have made since the problems started.

The stack on that engine might not be the direct cause of your problem, but taking it off might give you some more clues as to what is going on.

For sure. Thanks for the insight. I can't wait to solve this pesky issue.
