uprated fuel pump recons that better than walbro?

[Martin F]

Not if it's done properly.

There is a safe way of doing it where the pump will still cut out when the ECU tells it to (about 15secs after ignition on and the engine not starting IIRC) and there is an unsafe way of doing it where the pump is always on.

I believe Toyota had the switching from 12v to 9v to try and reduce pump noise and prolong pump life, both factors which are not really of high consideration on a modified car.

Granted no, but melting connectors in the fuel tank are!

The Bosch pump seems to be the one to go for now.

You said that sound and pump life were not important factors, i was merely pointing out that perhaps not having melted wiring and/or sparks in the tank should be 'more' important.

I think some confusion. I'm not aware of that being an issue on the stock setup, and in all fairness it shouldn't be an issue in aftermarket system as long as people specify cables and connectors properly and fit them correctly.

Expecting stock wiring to handle enough current for two Walbro's is madness even if you look at basic current ratings of 1x Stock Pump vs. 2x Walbro's

Im getting bored of trying to explain it really, its happened a fair few times now that i have heard of, it was merely to highlight that 'Walbro failures' that you alluded to are not that common, unless the wiring has been bodged.

Think you two are on the same wavelength now

In that case you may want to make your posts a little clearer. The way I read it you seemed to be implying that the stock pump and setup suffered from melted connectors and potentially sparks in the petrol tank.

Only if you read them in isolation.

You pointed out how poor the Walbro is, as it fails apparently, i pointed out that they usually fail if fitted incorrectly, badly modified fuel pump ecu etc, i just don't like to see a good product knocked based on inaccurate information that's all. Clearly i would be talking about stock units failing, as that wasn't even being discussed. Granted the OEM UK pump is superior to a Walbro in terms of flow for a BPU, but it doesnt flow enough, and isnt consistent enough for a single. Hence people fit one or 2 Walbros. Personally ill am fitting a Bosch unit.

Rob, i'm sorry but you're at it again. I'm not a grammar or language nazi, but the first part of your sentence you're implying that my post is only an allegation and may not be true, but the second part of your sentence indicates that they do fail.

You would or you wouldn't ?

Can you see why maybe the confusion?


For my part, it was only a few months ago that I started to hear of some Walbro's failing and it seemed to be discussed that although it was a good pump, maybe it's service life wasn't as long as the OEM unit. However there were no concrete facts, so it could be a freak few which are coming to light now that there are so many installed, it could be a batch issue, it could be a service life issue or any number of things. I was wondering whether due to the diversion of this thread maybe somebody would have heard what the common factor was.

I don't deny that the Walbro is a good bit of kit as so many people have used them with success over the years, and it is only just recently that I have heard of a any failures.

Comparison to the stock pump was drawn by me, as i've never ever heard of one failing, even on installations where people are using more than one.
