Description

MPFST, DUAL 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.

Great value for the price
Style: White, Size: 24" Jumbo
I have gotten smaller versions of this Lamb chop, my dog has loved them all the same but this one is great. It's big enough for him to carry around and it lasts a lot longer since he likes to tear them up fast.

This version is ok, but NOT for my boy-The 24in Jumbo version is the perfect toy for Kota-Ghost.
Style: White, Size: 24" Jumbo, Style: White, Size: 24" Jumbo
Adorable & nice but... I hate writing adverse reviews but I had to for this one. It lasted exactly 1 minute. 30 seconds of that was Ghost pulling the rest of the stuffing out to completely gut this Lambie. I know what happened-The material on the chest and the little red buttons were the issue. Cute as it may be, that material is terrible. My Great Pyrenees/AmStaff/Golden Retriever Mix boy, Kota-Ghost, very rarely tears his stuffy squeaky toys up. He is only 7 months old and has only shown interest in tearing something up if it was already broken(had an existing rip or tear)This is only the 2nd or 3 toy he has torn up in his whole life(and he literally has at least 30 stuffy toys(some left by my sweet Bella--she passed away in March but most are brand new because when I saw he wasn't a Destructo-Dog, I went a bit overboard buyin him stuffies-So much that my Hubs was not happy with me but he was secretly glad I did it😈.) See my review for the Jumbo Lambchop toy-That toy was and IS quite possibly the best stuffed squeaky toy available for bigger dogs. Only the MultiPet brand Jumbo tho-There are other brands that arent great. You can tell by the materials used on the face of the real Jumbo 24 inch ones from MultiPet. The Jumbo was a much better experience for us! I have also ordered the smaller one for him becuz he really wants the cat's lambie toy too. They have the 6 inch, not the "cat toy" version and they(and Ghost)love it. No one tears it up. I'll review it once his is delivered because while I know he doesnt rip the 6 inch one apart it is technically the cat's toy(not his) and we usually make him give it back to them pretty quickly. Ill review it when he gets his own & is allowed to do whatever he chooses. Hopefully he will treat it like Jumbo Lambie...Ok well, maybe not exactly that way cuz...Well, Lets just say he gets very, erhmm, frisky with his Jumbo Lambie. He doesnt like when we wash her but we do. Unfortunately he tries to take her outside in the dirt and/or in the pool with him. I will mention that more in my review for Jumbo Lambie. As for this standing up version-It MIGHT be fine for your dog or cat but it definitely was not durable for my Ghostie. It is a good size for a smaller/medium sized dog but definitely not good for puppies & especially those that still have their deciduous(milk/needle)teeth and not for even light to moderate chewers due to the material on the chest. That's what made Ghost tear his up. He nicked it with his teeth, a hole formed and that was apparently his cue to rip the squeaker out & tear the poor toy to shreds-He did have fun doing it tho. Haha. For some dogs this toy might be great fun. It is definitely a great brand and the jumbo version is Ghost's fave toy of all time. Pricing on all of MultiPet's dog toys are amazing and I hope they stay that way! We keep several of the Jumbo Lambies here in case one "goes swimming" so we can wash it and he has one to carry/cuddle or in case one gets temporarily left behind somewhere cuz he wants to take it everywhere he goes. We let him bring her along except for on walks
