Fuel is supplied to the surge tank by a lift pump, which in most cases is the OEM in-tank fuel pump. The volume of fuel inside the surge tank acts as a buffer to always keep the FST pump(s) supplied with fuel, even if the lift pump starves momentarily.\u003c\/p\u003e\n\u003cp\u003eThis volume is maintained by the lift pump as well as the fuel returning from the built-in fuel pressure regulator. Excess fuel in the surge tank is returned back to the vehicle's main fuel tank. The surge tank also provides a quick and easy way to upgrade any standard fuel system without opening the stock fuel tank. This is an excellent fueling solution for vehicles installing large demand power upgrades such as forced induction.\u003c\/p\u003e\n\u003cp\u003eThe Radium Engineering MPFST-R is the perfect solution for simplifying a high power vehicle experiencing fuel starvation during aggressive driving. When compared to a typical surge tank, there is one less port fitting. Instead, the built-in regulator returns low pressure fuel directly into the surge tank negating the need for an external FPR return line\u003c\/p\u003e\n\u003cp\u003eThe MPFST-R will accept 1, 2, or 3 fuel pumps. Refer to the pump compatibility section of each individual unit below to see a list of compatible pumps for each.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBUILT-IN REGULATOR\u003c\/strong\u003e\u003cbr\u003eRA-series regulators feature the first tool-less pressure adjustment. A jam nut and set screw are no longer required. With a simple turn of the knob, pressure will be increased or decreased.\u003c\/p\u003e\n\u003cp\u003eTo aid in adjusting pressure, there are incremental detents that provide haptic feedback to the user. Every detent equates to about 1psi of adjustment depending on current fuel pressure. Furthermore, RA-series regulators feature a 360 degree swiveling vacuum reference port that is double O-ring sealed. This is the first in the industry. It permits the installer to quickly point the vacuum fitting in any direction with no tools required.\u003c\/p\u003e\n\u003cp\u003eThe MPFST-R features an 1\/8\" NPT fuel pressure port at the regulator. An 1\/8\" plug is provided, or a fuel pressure gauge or sensor can be installed to adjust and monitor fuel pressure.\u003c\/p\u003e\n\u003cp\u003eThe built-in regulator is 1:1 vacuum reference capable. There are 4 interchangeable 10-32 threaded vacuum port fittings provided to suit different vacuum hose types. The reference port can also be plugged with the included screw for constant fuel pressure.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWalbro GSS342\u003c\/li\u003e\n\u003cli\u003eAEM 50-1200\u003c\/li\u003e\n\u003cli\u003eDeatschwerks DW440\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eMore compatible pumps are possible that are not listed here.
