Installed some 90 degree AN flare to pipe thread adapters for the intank fuel pump on my stainless fuel tank. One of them ends up point toward the back of the tank. Is there a trick to get it pointing forward or am I stuck purchasing a 180 degree flare to hose fitting?
Thanks,
Kevin

If by a trick you mean turing it past the other elbo, I found that I had to buy Earl's fittings and have one turned at a particular angle and the other would slightly rub when turning past it. The were -6s and both are on and facing forward. All my other fittings are Russell.

The two have enough clearance between them so they don't touch or rub when installing. When I tighten them (using a 5/8 wrench) one ends up facing towards the front of the car and one towards the back of the car. I'm contenplating using a larger wrench on the one to get to face the front.

a pipe thread is conical, therefore it stops where it wants to.
If you have an NPT tap you can tap the hole a bit and make it point forward.
be careful while doing it becaus going to deep means that you are FXXXXD

You could start over and rap it with extra teflon tape

The fitting you put in the tank are pipe thread on the tank end & flare at the end where the hose connects?

If so, put a strait pipe to AN fitting on the tank, then put a swivel 90 degree flare to whatever type hose connection on it. That way you can position it in the direction you want when you tighten the 90 to the strait from the tank.

Thanks for the input.

Scot, that was my original plan. Though I saw many installs with the 90 degree fitting. I believe there might be a height issue of it sticking to high and hitting the body when installed. Worth looking at again.

For most fluid applications the use of any 90* forged fitting is not optimal. They are simply drilled to make the fluid passage, hence the internal corner is not smooth and creates a choke point. The above mentioned use of a radiused tube 90* fitting is a much better option.

Personally, I do what Tiger mentioned all the time. Just turn the tap only a little bit more then test fit the adapter. Be sure to lube the tap and the fitting before doing test fits you do not want to gall the threads. Oh and do not put a bigger wrench on the fitting and try to torque it around from where it is now. That is a great way to destroy things.

The full flow hose ends for dry sump applications allow you to tighten the NPT part of the fitting so that it produces a good seal but still allows the hose end of the fitting to be rotated to whatever position you want. These fittings also eliminate the flow restrictions that CarlC mentioned and makes for a better engineered plumbing set up

Ive used these fittings on remote mounted oil filter/cooler applications with excellent results.

Those are trick and the perfect solution to the current forged 90's and straight AN hose adapters on my gas tank... I'm space limited between the fittings on the tank and the rear end cover. I had no better solution at the time than the forged 90's and straight fittings but those Russells fittings look like the hot ticket.

Are they lockwire & viton o-ring full swivel fittings? It looks like they are.

Actually I posted the wrong link.....sorry I was in a hurry (Im at work).

This is the same thing as the dry sump fittings only with NPT threads that you need. The dry sump fittings are straight thread and can be had with or without an O-ring for sealing the threaded end.

You'll need one of these in the correct size for NPT.

My apologies for the screw up.

I'm limited by the height (clearance between the tank and trunk).

myclone - thanks for share those fittings. I will have to order some.

thanks.

No big deal-- I was looking at their ORB fittings too. Gotta keep those things in mind for the future!
