ebay sell walbro kit for s4 and s5
i want to know the difference between ?

because i have a s4 fc with a s5 engine
is this will affect if i purchase the s4 kit
just to be sure!

thank for reply

 

the gas tank is what matters. the S5 is larger. in truth, get a FD fuel pump for cheap. Got mine for 5 bucks and it flows at 250. 5 less than a walbro but 100 dollars less from your wallet! But, if you stay walbro, use the S4 one.

 

S4 is kinda long and slender, s5 is fat and stubby. However, I've managed to get a s4 pump to work in a s5 car, you just need a longer peice of rubber fuel hose and you have to do a little cutting/custom wiring. You will need the s4 kit for your specific application.

 

ok thank for information
i will go for fd pump!

 

the fd pump is flowing 250 lph??

what is the major difference between fd and walbro pump?

 

Fd pump would be second hand, walbro is new and made for your application. If the FD looks like the s5 pump, I'd imagine it would be difficult to retro fit for s4 cars (which is what you need, an s4 style pump, which the walbro will fit.)

 

I've seen people fit FD pumps in s4's no problem.

 

also make sure you order the HIGH PRESSURE pump..if it does not say high pressure then keep looking...

 

Stop spreading bullshit like this.

The graph clearly shows the Walbro outclasses the stock FD fuel pump.
This was done with real-world testing.
Not factory specs...

The only difference between the S4 versus S5 Walbro is the top fitting and "accessories bag".
The fuel pump is IDENTICAL internally and flow specs.

I put an S4 TII pump in my S5, I cant see it being all too much more different/difficult.
