AEM's 340LPH E85-compatible high-flow in-tank fuel pump features robust internal construction designed to withstand the low lubricity of ethanol and methanol fuels, and is tested to work with ethanol up to E100, methanol up to M100, and all types of gasoline. Built for in-tank mounting on high-performance naturally aspirated and forced-induction vehicles, it has a compact 39mm diameter that fits most applications and an offset inlet design that eases installation. The kit includes a wiring harness, pre-filter, end cap and rubber buffer sleeve, and every pump is individually tested to flow 340 LPH at 40 PSI before packaging.
This product carries a California Proposition 65 warning per the manufacturer's data.

FAQ
What fuels is the AEM 50-1200 pump compatible with?
It is tested and compatible with gasoline, ethanol fuels up to E100, and methanol fuels up to M100.
What makes the offset inlet design useful?
The offset inlet on the 50-1200 eases installation in tanks where a straight inline inlet does not line up as easily, while maintaining the same 39mm body diameter and flow rating.
How is the AEM 50-1200 pump rated for flow?
Every pump is individually tested and guaranteed to flow 340 LPH at 40 PSI before it is packaged for sale.
