Fuel Pump Options

[steve200b]

Hi

Im looking for some peoples feedback and opinions on a replacement fuel pump for my 044, I currently have a carter black lift pump into under car surge tank in a R30 skyline with around 300kw I have had enough with the 044's. I have replaced 3 in 12 months, I have an inline filter etc. I have been looking at the SX performance pumps what other options should I be looking at?

Thanks

Hi Steve,

Why are you killing the 044s?

They're a great pump and it's very unusual to see 3 let go in 12 months.

I'd be looking to solve the problem of why they're dying rather than buy a more expensive replacement pump and hope it doesn't die.

What ecu are you running? If you have a spare PWM output I would be seriously looking at the Fuelab variable speed pumps. Be aware, they need at least 10an lines into the pump to limit cavitation. (Same thing could be killing your 044)

I have a Nistune for now ant the pump is wired from the battery etc. I assume it must be contamination that's killing the pumps

I still have the std tank in the r30 so no internal pump. I might need to change the tank to make it easier to clean properly

Hi Steve,

Do you run a filter between the tank and carter?

You can use a cheapo clear plastic Ryco one which will allow you to see how dirty it is and when to replace.

The carter is a vane type pump and will not filter anything.

If you have the time and CBF, maybe spend a day and flush the tank.

I'd also check power supply to the 044 at idle and under load if possible (hard to do if it's mounted under the car, but you can bodge something up with some long (decent gauge) wires off the pump terminals to a mate reading the multimeter in the back seat. Needless to say, don't cross the wires...)

Definately must have an issue if your killing 3 044s in a year ive had mine for 3 years as my surge tank pump with no filter in between lift pump and surge and have no problems and pre engine filter is relatively clean yearly. You probably have a dirty fuel tank and that might be getting into the 044. Have you cut open the broken 044 and checked the internal filter what it lookss like?

Looks like I have some cleaning to do this weekend lol
