Of late there is a lot of Walbro fuel pump for sale in the speed shops. Most of them hover plus minus the price of RM400.

Some has admited that it's copy item made in China. For a user out there looking for the product, how can one be assured that what is bought is the genuine item from Walbro?

Anyone know who actually sell the genuine Walbro pump in Malaysia?

Read in a foreign magazine saying that genuine Walbro will have the the wording stamped on the pump itself.

one of thing to determine is by the 'round'clip to attach the filter..original is like 'bunga'wan...china made just round only..
and this is some info on diffrent on walbro pump.usually find 255liter/hr

We are commonly asked "what is the difference between the Walbro pumps?

I thought they only had a 190lph and a255lph pump...?" Well, there are actually quite a few different pumps that they offer. First, we have the 190lph, the 190lph-HP, the 255lph, and the 255lph-HP. Then we have the "flipped" versions of the 190lph, the 255lph, and the 255lph-HP (no 190lph-HP). SEE PIC BELOW. These pumps have the inlet rotated 180 degrees from the inlet. The reason is to allow for a greater number of fitments. With these 7 pumps, Walbro can fit numerous vehicle applications. Other than that, each "series" of pumps is the same in terms of fuel flow characteristics.

Another question we are asked is "what pump do I need and what is that HP about?"

That questions is simple but technical at the same time.....to be continued...

Regarding the HP question, that is fairly simple. If we take the two 255lph pumps and look at the pressure curves we see that they are very similar until about 60psi. After that point, the standard 255 pump starts to die off whereas the HP keeps going.

To use an example to illustrate pump choice, we will look at a turbocharged Acura application. On these vehicles, the OEM fuel pressure regulator is referred to as a 1:1 regulator. What this means is that for every pound of manifold pressure (boost) there will be a corresponding 1 pound increase in fuel pressure. If the base fuel pressure is set at 40lbs and we introduce 10lbs. of boost, the total fuel system pressure at boost will be 50lbs. That sounds good and will work fine with a standard 255 pump but there is one small problem.

The problem is that we still need more fuel than the 1:1 regulator can effectively deliver. One way would be to add a larger set of fuel injectors and use an aftermarket engine management system to control them. The other, more commonly used method of fuel enrichment is the rising rate fuel pressure regulator or FMU. This device functions in a 4:1 (or more) ratio and will increase the fuel pressure 4 pounds for every 1 pound of boost. If we once again set our base fuel pressure at 40 lbs. and add 10 lbs. of boost we will now see 40 additional pounds of pressure for a total of 80lbs. of fuel rail pressure. This goes beyond the capabilities of the standard 255 pump and mandates the use of the 255HP pump. From this we can see that given two different engines, both with a hypothetical 400hp, the one with the larger pressure requirements will need the HP pump, the one with the smaller requirements will not.

malaysia walbro distributor company is ti automotive,so u can ask the dealer show u the latter to prove the walbro is original anot and the latter have a chop,the chop is us technology project sdn bhd,and one more method u bring the fuel pump to TI to prove the fuel pump
