Aluminum injector caps

I don't think you need any 'T's. My truck has the left/right bank crossover at the rear two cylinders, so only 1 more 90 for the passenger side that goes to the 'T' for the right side/tank return.

Interested in a couple sets as well!

A turbo setup you need 2 90s, 2 dead end, 2 T's and 2 straight through?

3-90's, 1-dead, 2-T's, and 2 straight through I think.

If I remember correctly it went something like this. Not sure if my T's are in the correct position but you get the idea.

that is correct, and the tees make it easier to crossover without the turbo cooking the one at the rear.

Really, when it comes right down to it, you do not NEED anything other than the standard double barb inline. There is no required routing, and you can in fact, route however you would like. As long as each injector can return fuel to the tank, the hoses can go wherever the heck you want them to, and a dead end cap can be simulated with a rubber plug and a clamp, and T's in the line can be done with standard plastic barbed T's and not fancy 3 barbed return line caps. Call me a spoil sport, but spending more time CNC'ing fancy variations is not needed, unless you just really enjoy doing that!

personally, I'd be very, very interested in a set with a single -4 AN threaded fitting on them, I'd much rather do them once and manifold braided stainless lines together to permanently eliminate associated issues

I am not sure what that is could you post a picture of this?

something like the last one is what I have in mind, even if you could just make them with the barb large enough to thread myself.......

Having the AN fitting would be pretty trick. I know after I switched a few oil lines and fuel lines to AN fittings a lot of my small leaks and seepages went away on my Fummins.

You would have to keep it from pulling while you tighten the hose up.

Maybe some push lock or twist lock hoses could work also.

But definitely overkill.

I personally think AN fittings wouldn't do a bit of good. The o-rings are really the weak point.

 

[Ruger_556]

Yeah, but caps break if you look at them funny

 

[thx997303]

Which an fittings do nothing to prevent.

What about push-to-connects? I don't know what the flow requirement is on the return system but 1/16 or 1/8 npt threads into the caps open up just about unlimited posiblities. Might even be able to go with 10-32 stuff but that might be a little small and restrictive.

I dont believe that anything done to the hose barbs will fix the prolem with our return lines. The problem seems to be that the caps are able to move around on the o-rings freely. This makes for a tenuous seal.

Until we figure out how to install the caps and keep them stationary, the caps will continue to be an issue.

Thinking on it, we have a shelf on the top of thr injector, and one below the return line area. If we made a cap that had a taller portion the fuel line could bear on, and used copper sealing washers on these two shelves, we might be able to install the return caps by threading on the fuel lines. I think this would solve our issues. Ony problem is, i dont have the abikity to make and test these.

Their cool looking, but 15 minutes a piece on a machine that should be making a minimum of $100 an hour.
