Hello,

I have a 92 Camaro RS - hard top. Swapping to a built 5.3 turbo combo. I'm replacing the tank, upgrading fuel pump to the aeromotive 340, and using -8 AN lines to a TBSS intake with holley fuel rails.

My questions for the guys and gals who have done it. How much line should I order? I have 20 feet, but I'm thinking that will not cut it with the fuel regulator and fuel filter cuts. Should I order another 20 feet? Stuff is expensive so I'm being cautious before I order too much!!

Thanks,
Tony

 

Those of us who have done it recommend reusing your factory fuel lines unless they are leaking or damaged.

That AN hose has a lifespan, doesn't fit as well, and looks tacky*.

What are you going to do about wiring for that 340 pump? How much power are you planning to make?

*last point is my opinion.

 

Looking for 6-700 hp. This build is a complete swap. I read on other forums that the stock lines will only support roughly 450 hp. I understand the AN drawbacks, but I do prefer to move forward with it. The fuel pump I have is a complete swap with factory off Summit. Comes built for the 82-92 Camaros. Should be plug and play. If not, I'll figure that out.

 

Not sure how much you will need but I ran new SS hard lines under the car with AN fittings and only used the braided hose in the engine bay and right over the axle to the tank. I’ve read of issues running braided hose along the entirety of the system and many have complained of fuel smell from the braided lines. Just a thought is all.

 

I am running braided lines from tank to regulator/rail and I haven't noticed any smells. Although, that is certainly a legit complaint and not all hoses are the same. The ones I am using from RaceFlux state their liners do not leak vapors, and too be honest, they are right. My garage doesn't stink like fuel. I liked the flexibility of the braided lines, although the stock lines are more robust. PTFE lined would be your best bet to ensure lack of vapors but I have yet to experience any issues. I am running Aeroflow in the engine bay and RaceFlux to the tank. I do have mine jacketed in a fiberglass heat shield though. I did that due to close proximity to my dual exhaust. In the hottest heat, it hasn't been a problem.


Edit: As for legnth? Use some romex wiring to trace your path. You will always need more than you think.

 

yes, the new style braided lines are PTFE (lined with plastic) and they will not leak vapors like the old style braided lines (which still exist too).
I got all my fuel system parts/lines/pump from racetronix. Real good stuff.
I run a 340 pump and decided to do a -8an ptfe braided feed line and a -6 return line with a magnetic in line filter nad all upgraded wiring with a relay. again all Racetronix.

 

The Actual Hose better be made of PTFE and NOT some variant of Plastic Compounds!

Otherwise return what was purchased.
Pressure and Chemical Safety Standards are based upon the use of that particular PTFE Compound.

 

I use hard line where I can and hose only where I need relative movement at engine and fuel tank. 3/8" and 5/16" metal tube will clip right into factory clips under the car. The 3/8" NiCop tube (copper looking color) is infinitely easier to work with than stainless steel and is large enough that it has sufficient strength to retain its shape. That NiCop stuff gets pretty soft with smaller brake lines, I find steel a lot easier to work with in that case.

The hose we all use with -AN fittings isn't really meant for street use where long-term durability is needed, and exposure to the elements. It's for race cars where a flexible line is desirable to help avoid fuel spills when the car gets crushed up in a crash. It's not like the race teams are leaving that hose on the car for years and years and years.

I replace my hose every 5 years or so. Next time I'm eliminating it and going to do something else more like the OE cars with the plastic tube, just don't know how yet.

If you think the hose was expensive.... then you haven't bought the -AN fittings yet.
