Choosing Line Size: Choose -8 feed and return for dual pumps systems. We recommend -10 feed / -8 return for triple pump systems.
- We suggest -8 feed and return in any dual pump setup, simply because there is no measurable benefit to running a -10 feed with any dual pump fuel system. However, selecting a -10 feed is a good choice if you're planning to possibly upgrade to a triple pump system later (via our triple pump upgrade program). Of course, it is possible to run a -8 feed and -6 return; however, most of our customers find the fuel system installation is more flexible when all the fittings are the same size.
- We suggest -10 feed and -8 return lines allow any triple pump system to operate without restriction. However, -8 feed/return may be used if you're running three small fuel pumps (i.e. GSS342) or if your fuel system choice was marginal over whether to choose a dual or triple setup. So, if you're making 1100 rwhp on E85 (which is possible on a dual pump setup if your build is very efficient) but you chose to go with a triple pump setup, we would suggest a -8 feed/return since you don't need every ounce of performance out of a triple pump setup.
Choosing Fuel Line Type: FlexLP vs PTFE vs Startlite
Startlite will emit fuel smell and should only be used on cars kept outside or in detached garages/shops. Cars kept in attached garages should use FlexLP or PTFE, which will not emit a fuel smell. PTFE has a stainless outer reinforcement and will last forever, whereas FlexLP has a soft black/gray nylon outer braid and some insulating properties. (no NVH and more friendly with fuel pressure sensors/gauges). Our preference is FlexLP since it is much easier to work with as compared to PTFE which is not flexible.
- FlexLP has the best ratio of pros vs cons than our other hose offerings. Most importantly, it's low permeability prevents fuel vapor smell when the vehicle is parked in closed areas. Cosmetically, some of our customers prefer the black outer braid over the stainless braid of PTFE.
- PTFE is the most resilient to heat and chemicals than any other fuel line we offer, and likewise can be expected to outlast the vehicle. The PTFE core cannot be permeated by any fuel, and therefore will not emit a fuel smell when the vehicle is parked in closed areas. Cosmetically, some of our customers prefer the look (or contrast) of the stainless outer braid.
- Startlite is race hose, and therefore we only recommend it for vehicles that are stored outside or kept in a detached garage or shop. Fuel can permeate the lines and will usually emit a fuel smell in the storage area.

This fuel system generates substantially more heat and capacity than the original fuel system. The high-powered fuel pumps make much more heat than the factory pump and the composite fuel tank construction acts as an insulator and stores heat. Additionally, the shape of the factory fuel tank limits the pickup capacity of this fuel system. The user (driver) must keep more fuel (than normal) in the tank at all times to minimize heat damage and ensure adequate fuel pickup.
