Fuel Hard Line - Rubber Insulators

Recommended Posts

My fellow HybridZ friends,

 

Just finished bending up my stainless steel hard lines and now I'm looking at cutting up some new rubber insulators. The stock ones are trashed/crumbling.

 

I'm looking for a rubber similar to the energy suspension urethane, the red stuff. Does anyone have any idea where I could get something like this?

 

Thanks fellas!

Mc-Master Carr supply company has quart-sized kits of pourable two-part urethane in several durometers.

 

If you want a block of it to cut and drill, they can probably help you there as well. But if you can make a silicone or cast-plaster mold of what you have, you can pour a replica in equivalent or more durable durometer pretty easily.

 

They can ship from LA or Chicago to you---probably the same either way.

They are in Texas, but are more geared toward people buying sheets of stuff for production purposes.

 

TPC in Rancho Cucamonga does some neat prototype work...again more for production geared stuff, though:

If you are decent with a drill press, and carving wood, I'd get the self-mix kit from McMaster-Carr, and make up a buck out of balsa wood, then take a plaster casting off of it as a mold. You can drill and split it as you choose. Basically make yourself some urethane square bananas that will fit in the stock holders and you will be set. Just remember there is some shrinkage usually, so don't pour a lot till you have the shrinkage compensated for in your mold---with plaster: scrape scrape scrape and then recoat with release compound. Remember they have to compress around the pipes as well---don't leave them rattle around or the harder stuff can literally eat your hard line!

Wouldn't poly bushings around your fuel lines be a bit too harsh? I mean, I don't know the durometer of the stock rubber, or what poly can get down too, but it seems to my uneducated self that just buying a large chunk of rubber would be your best bet.

Bingo.

 

I just threw poly out there because it appears to be of good quality. You're right, I just need a generic block of rubber to cut from.

 

Any ideas?

Buy some rubber cord stock in a rectangular or square profile, if you can find the right size. Get a sharp exacto and cut a v-groove where the line will pass through.

 

 

 

 

Try here:

Hmm....getting warmer. I'm not sure I'm looking for so much a "cord" but for more of a straight block of rubber. Basically, i just need to cut out some rectangles to replicate the stock pieces.

 

Anyone else?

 

EDIT:

 

What do you guys think?:

Look at McMaster for SBR rubber, or other sheeting like conveyor rubber.

 

Old conveyor belt is tough stuff with reinforcement.

 

Cutting the rubber, and making round holes in it is not as easy as it sounds.

Buy a roll of McMaster-Carr part number 9700K14 (as suggested above), heat up an appropriate diameter steel bar, and burn grooves in the rubber. You'll need four pieces of rubber for each clamp (two side by side ont he bottom, two side by side on the top).

Just saw this, sorry John!

 

I guess I'm a little confused regarding your idea. Would 4 pieces make up one insulator?
