FMU users beware!
 

Holy $hit!

I just installed new inline BOSCH pump in the engine bay area. After starting car noticed that there was almost vacuum creating inbetween intank and inline fuel pump -> so I had to remove intank one.
Geez... that intak pump is like 1/4 size of this inline!!!

If using FMU there's no friggin way that little pump can pump enough gas pressure for FMU!
Also, another thing I noticed - hose that is connected to fuel pump outlet out of reservoir - it connects so easy (hold by only a plastic clamp!) - I can't belive they used this kind of connectors for gas *under pressure*.

Please, if using FMU *replace* fuel pump, and put better hose for those 10" from fuel tank to metal hose that goes to engine bay.

the walbro 255 is aobut the same size as the stock one. just becouse of its size means ----.

Re:FMU users beware!
 

I've never used an FMU, but I was under the impression when using an FMU it was a golden rule to get an inline pump, because the stock nor the walbro 255lph can handle the high fuel pressure an FMU causes.

fmu does not create pressure, it regulates it and raises the pressure to the injectors proportionate to boost. Everybody i talk to says its hard on fuel pumps
