OTL Fuel Systems

OTL Back Half Surge Tank System - GD Chassis


The complete OTL Fuel System includes everything you need to support fuel demands up to 1200whp on E85. Fuel lines are braided stainless with a PTFE core to handle any fuel type and the exterior is protected with a smooth PVC coating. All lines are pressure tested after assembly.

Our fuel system is split into two parts and either kit can be used independently of the other.


Front Half Line/Rail Kit

Includes rails, PTFE lines, regulator, gauge, fuel filter w/check valve and adapter fittings to connect directly to the stock hardlines at the firewall. EFI adapters are also included for connecting to the stock hardlines at the firewall for feed and return. If combining with our back half surge tank kit, the front lines connect direct to our -8AN feed and -6AN return lines below the location of the stock hardlines.

Back Half Surge Tank System

Includes sending unit hardware, aluminum surge tank, MagnaFuel inline fuel pump, PTFE lines, ABS mounting board and all required fittings. The mounting board sits in the spare tire well and is fastened down using your OEM spare tire retainer. All can be hidden under your factory trunk board and carpet for a clean install that can still haul the groceries. The back half system terminates at the firewall below the stock hardlines and can easily be connected to most upgraded front line/rail kits.

Street Series ignition Coils

Off The Line Performance is excited to announce the arrival of the Street Series Ignition Coils for the Subaru EJ20/EJ25 turbo platform! Our coils have been tested on vehicles ranging from stock power level to over 1,000whp levels with exciting results. Improved drivability and power delivery across the board!

10% more power output than OEM

Increased output provides smoother idle and smoother power delivery throughout the powerband. A more powerful spark also helps prevent spark blowout and allows high boost applications to maintain a larger plug gap. Our Street Series ignition coils will improve the drivability of any vehicle!

Plug-N-Play Fitment

Our Street Series line is plug-n-play for any EJ20/EJ25 turbo application listed below. This part number can also be used for USDM EJ20 black coil applications by swapping coil boots and tuning for correct dwell settings.

No Tuning Required

A tune is not required for the listed applications at any power level. You really can drop them in and go but our testing has proven to give a pro-tuner better timing control higher in the power band. This means they will have the ability to more efficiently tune your setup and release more horsepower!
