PA Series In tank fuel pump module for retrofit EFI applications. 

This In-Tank Fuel Pump module can be used to retrofit an internal fuel pump into your original gas tank.   

This kit gives you everything that you need to install an internal fuel pump into nearly any tank. The PA Series fuel pump kit features a reservoir tray that eliminates fuel pump starvation that is common on non-baffled tanks.  A properly installed internal fuel pump will essentially eliminate any issues that are common on external fuel pumps such as vapor lock and cavitation.    

The pumps listed are capable of running up to 100 PSI and they will deliver a varying amount of fuel (gallons per hour) depending on the pressure.

Awesome Kit

This kit is awesome. It's seemed expensive to me. But well worth the $$$. Instructions are very clear. I converted a Jeep CJ fuel tank to a in tank pump for my 57 IHC pickup build.
