Walbro 460 Fuel Pump

Recommended Posts

Is anyone using a Walbro 460lph E85 compatible fuel pump in the standard sender unit and if so was there any drama with higher fuel pressure / richer mixture associated with the swap? Cheers!

Iv got that pump in the stock sender in my ute. Running standard lines and reg. The reg and return lines are just up to the job but they recommend a new reg and return lines to avoid high fuel pressure at idle.

Your most likely running above 4 bar delta now more in the vicinity of 70psi plus.

There are ways to mod the cradle to allow better return flow.

I have the walbro 460 in my surge and had up around 90-100psi and so had to get a reg. Even though yours is as a lift pump in the tank I would imagine fuel pressure would still be quite high

Oh dear! I can see an aftermarket regulator in sight.

I might put a gauge on it and see exactly what the pressure difference is.

Are you guys using the standard wiring configuration or have run a new power supply to the sender?

I'm also running an intank 460, got as replacement drop-in unit cos too lazy to swap pump only

Needed new relay as well as reg, relay was approx $120 from KPM from memory

Geez that's up there. Is there anything special about the relay? I was going to run a fused feed from the battery and switch a relay via the original pump power feed.

You're right it's pricey

Bought it because I didn't know any better

Nothing special, pic of it in the following link:

$165.... yeh kpm also :ermm:

And I checked my emails...relay was actually 135 not 120....

All jokes aside, what other regs and plug and play relays are available off the shelf? and how much

Admittedly my research wasn't up to scratch

They had what I needed so I lined up and bent over

Well stuff that then. Cause if I bought the above ebay kit...it would be $438 + $165 + $135 + kpm postage? = $738+

So I will just stick to kpm complete kit cause $895...and at least they've done the research to guarantee no surge.

Unless of course I find a cheap surge for $400-600 second hand or new (as they pop up from time to time).

Made one the other week for a fella reg/wiring included with a more efficient return system for under $500 fitted....all new exact same parts.

I might be bias and say its better though....will it guarantee no surge?....no it wont ;)
