Description

MPFST, TRIPLE WALBRO GSS342, PUMPS INCLUDEDWhat is a fuel surge tank? A fuel surge tank (FST) is designed to prevent fuel starvation to the engine on vehicles with inadequate fuel tank baffling. 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. This volume is maintained by the lift pump as well

What is a fuel surge tank?
A fuel surge tank (FST) is designed to prevent fuel starvation to the engine on vehicles with inadequate fuel tank baffling. 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. This volume is maintained by the lift pump as well as the fuel returning from the 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 upgade 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. For more information on how a fuel surge tank works.

Multi-Pump Fuel Surge Tank (MPFST)
Recently redesigned for 2019, the Radium Engineering MPFST is the perfect solution for high power vehicles experiencing fuel starvation during aggressive driving. Multiple high flowing fuel pumps can be used in the surge tank.

Because the compatible pumps utilize a check valve, the MPFST merges all pumps into a single outlet simplifying external plumbing. NOTE: The brushless Ti Automotive E5LM MPFST includes check valves.

This "PUMP OUT" port is 10AN ORB threaded but comes preinstalled with a -8AN male adapter fitting. The "OVERFLOW", "SUPPLY", and "RETURN" ports are all 8AN ORB threaded but come preinstalled with -6AN male adapter fittings. All of these fittings can be swapped out with different sizes (sold separately).

The brushless Ti Automotive E5LM MPFST pump outlet merge collector.

When fuel enters the MPFST through the "SUPPLY" and "RETURN" ports, it gets redirected and runs tangential through the canister creating a swirl pot. This helps eliminate unwanted air bubbles and fuel foam that can affect fuel pump and engine performance.

The pumps are mounted using an anodized aluminum bracket. All internal wires are gasoline, ethanol, and methanol compliant. The brushless Ti Automotive E5LM MPFST (shown above) utilizes a standard press-in filter sock included commonly with the pump.

All other (brushed pumps) pumps use the provided stainless steel mesh inlet screen for pre pump filtration.

The pump power connections are handled with specially designed high-current electrical studs. Necessary ring terminals and hardware are included with every surge tank.

The underside of the MPFST is suitable for uneven surfaces commonly found in the trunk of a vehicle. Stainless steel M6x1.0mm socket head bolts are included for custom mounting.

Very high quality suit for the price! Might as well buy, then rent.
Color: Deep Grey (Stretch Fabric), Size: X-Small
I bought this for my son for his Prom, as he decided to go last minute. He weighs around 125 pounds and is about 5'11. The XS fit was pretty amazing. As the supplier says, follow the size chart on the second picture. There is also some stretch to the material and the pants have belt loops. The only thing we noticed that we didn't like is that the sleeves were a little large at the opening around the wrist. Since the cuff-links are sew on, there isn't really on easy way to adjust this. All in all, this was a great purchase and I would highly recommend YND suits.

Good buy for sure.
Color: Burgundy (Stretch Fabric), Size: X-Large
The suit looks and feels great for the price I’m 6’3 190-200lb and ordered a size XL. I’m going to have the sleeve dropped a tad bit and waist taken in. The hem is perfect and to my liking. Will be buying 2-3 in the future.

We’re happy!
For the price, this suit was great. My son is a bigger guy and when we rent tuxes, the pants always look terrible. This one, we were happy with. He usually wears a 2x in clothes but we sized up to the 3x. He’s 6’2” and prob 270. Maybe more but the vest was still a little snug.
