Happy 4th ! 

 

Sorry no scenic background...we don't get out much... haha

 

Cant thank you enough Captain 80s for those awesome infills

 

 

Looking good!

 

I'm liking the fuel pump mod.  Is the back side of the pump supported?

No its not but with that...what would you call it...gusseted bracket... its stiff as hell.

But the 90 deg bent tang of the fuel pump bracket is certainly not.  Stock, the bracket and the pump get to rest on the subframe rail.  The bolt hole just keeps it in place.  Over a short amount of time it might just bend down/back to the point that the back of the pump is hitting something and be ok.

[tsmitty]

Sorry I'm not making things clear...

BTW that extension bracket I used is a lower coil mount, I think.. anyways that bracket has a reinforcing bend that makes it very rigid.

If you look at the stock fuel pump mount bolted to the sub frame; it is actually suspended, suspended only by the bolt. Take a look, it doesn't rest on the subframe at all. I was concerned about that as well.

Coil mount!  Of course.

 

Gotcha.  But typically when you start to tighten that bolt, the bracket rotates to the right and contacts the subframe. 

 

 

 

I'm sure it's just fine.  I tend to overthink some things.

Yes, and I let it, torqued the bolt down and the bracket will not rotate away from the fuel line.

[tsmitty]

I've seen some of your safety wire techniques. that would be a trick place.

[Captain 80s]

I remember now the extra little "gusset" the fuel pump bracket has at the 90.  A few test rides would show any issues I'm sure.  Just with it up and so suspended now, my mind goes there thinking about the accumulative effects of constant bumps and jolts.  Easy enough to address if needed.

And I'm sorry to say thats your department... 😢

but yes I know exactly what your saying...that much further away from solid securement...kind a thing

[tsmitty]

there is no anti-rotation at that top bolt. It would be nice to use that little locating tab on the coil bracket I'm using but thats probably overkill...

Yes.  You can have strong brackets, but with each added one strength gets lost and leverage increases.  I've learned many times how brutal actual street riding can be.  I had some cowl brackets on my 500 race bike that had zero issues in years of racing.  One ride down to Ballard for a bike night and they were toast.

I'm just thinking of using one of the mounts up behind for the reg/rect and coming down with another small, simple bracket to the back side of the pump bracket.  Shit, even a zip tie from the back rubber suspension mount up to something there would do the trick to take A LOT of stress off of everything.

[tsmitty]

Well after the old girl is sunning herself, I'll take a look on the back side of the fuel mount for another securement spot.

up to the old rectifier mount or somthing

 

[tsmitty]

yup what he said

 

[tsmitty]

So here we go...while digging around, looking for secondary mount I noticed interference between back of f/pump and the rear fender snorkel. I made that change by mounting the f/p bracket on the other side of the coil bracket. So the tab on the coil bracket has to go...or get changed to an anti-rotation tab. The secondary mount location will be at the tool compartment. (I didn't use that bodacious screw...)

 

 

I think I'm golden...!?

[Captain 80s]

Bam!!!  

 

Hell yeah.  I may be using much, if not all, of this when needed. 

[tsmitty]

Thanks Captain.

 

Oh yes I did..  haha

 

[tsmitty]

Hey Captain 80s... This is the fuel line I'm using from tank to carbs. the clamps I have can be sprung with your fingers. Not very confidence inspiring, there is no leaking but I done like it...

What would you recommend.

Thanks

 Post pic of the clamp style.

 

There are a few varieties that sometimes get moved around on bikes.  There is a wide style that can clamp quite strong, but your fuel line likely has a smaller OD too not being double walled reenforced.

Pictured on my fuel pump, you can pinch them open pretty easy.

Oh, yeah.  Duh.  Your fuel line is smaller OD, and I think the clamp is out of it's sweet spot.  But Honda does have another version that provides a stronger clamp.  You might have to try the next smaller size of your style, maxed out to get over the line. 

 

You can always run small hose clamps, I just try not to whenever I can for servicing. 

[Captain 80s]

You can "shrink" those clamps styles down to a smaller size too, I've done that on some in between applications.

I'm thinking that might be the plan; I got one of those multi-size clamp sets last year and couldn't use any them. What you see up there in the pictures is what I was able to scrounge around the garage at the time.

Can the clamps I have be safety wired slightly tighter..?

The design of that clamp, I'm not sure how.  The tangs move away from each other to get tighter, I don't think going around the back would quite work out.  Maybe.  You could try I suppose and see what happens.  Sucks when you go to service something.
