DIY WALBRO 535 FUEL PUMP/EKPM MOD BMW 335i!

[@piotrek4000]

I just installed 17t's on my car 2 weeks ago, I also went with a Wallbro 535, I did a very similar install except I retained the stock venturi, do you have any problems with fuel starvation? Also, keep an eye on your stock wiring, the 535 will draw over 30 amps and the stock wiring has been known to melt at the connection on the top hat, real dangerous around fuel. I went with an ET3 Designs stage 2 EKP module and wired it and the pump with 10 ga wire fused with a 40 amp fuse. A little pricey, but total piece of mind

I also added bulkhead terminals to the top hat so I'm not using the stock pin connectors and this way the fuel tank is still a sealed system (running wires directly through the hat and trying to seal it won't work, the fuel will wick up the wiring on the inside of the wire insulation).

@@twitchkillgod2985 at some point i think you will have an issue if its still a stock ekpm

@@EvanCaron did you have any issues I’m planning on doing the same thing you did with the fan and thermal heat sinks

@@EvanCaron I believe it depends on the year model as the 2009 and up have ekp3 which is allegedly better suited for the pump upgrade

[@leebrackin7021]

What was the cost of all the parts? Curious of the price for diy vs buying both pump and ekp already upgraded

[@EvanCaron]

was around $421 cad for everything. like $311 usd
