Does Walbro Make A Direct Fit Fuel Pump?

[R33GOD]

As the topic is stated. if so how much?

thanks

[MANWHORE]

It is called a direct replacement. But it's not really. It is not like the tomei one. The tomei one is literally everything you need and more is supplied.

fuel tank gasket, bracket, pump, fuel pump sock, etc etc. EVERYTHING.

The walbro needs mods to wiring to fit, needs to be mounted, no nothing is supplied etc.

[MANWHORE]

also, the walbro flow rate is not as much as it says - their rating is not the same way of rating it as other pumps.

The tomei flows HEAPS. like crazy amounts. I can't remember when i converted it, but it was somethign like 270 lph.

A walbro is normally about $150.

One of our fellow guys who's in the same situation as us - installed turbo, changing pump, getting tune in a bit, has just got a tomei pump. For $340, it's pricey, but it's a massive pump, it's brand new, and it fits straight in.

Cheers

nismo also make direct replacement pumps

fitings and labor do add a bit to the cost of the walboro/bosch ones but not that much

the direct fit ones are not much more $$$ from places like nengun so worth considering

[R33GOD]

stuff it then.. i'l get a tomei

yeah im on now

[MANWHORE]

really? I can't see you.

if u get the r33 gtst kit for the walbro it comes with the pump, the rubber mount to use in the stock cradle, a new hose for the top of the pump and 2 new hose clamps and the sock on the bottom of the pump too

only mod needed to do is cut the old positive and negative wires and join the new ones with either crimps or solder/heatshrink

but as stated, if going for higer power go for a tomei as they flow much more

the kit was about 190 delivered from ebay, gss341 i think the part number was

thanks tek.

[MANWHORE]

tek, you didn't mention that the tank seal normally expands when you take it off, and it miht not go back on properply.

The good thing about the tomei pumps is it comes with a new one of those.

I can't remember who, i think it was either bass junky or abobob, did a test on the walbro, and it ran dangerously low on flow - they aimed the return line into a bucket.

[Guilt-Toy]

I have experienced the same with the walbro. I have had 2 in my car and both were the same. Last time i had the car on the dyno i was running a flow / pressure test on the return line and found the flow went down to .2 litres per minute back to the tank on full boost.

These pumps are not very good at holding pressure they can do it for a short while but lose there flow.

I recently had to turn the boost down to 9psi because the pump started failing. got myself a 044 last night to chuck in.

Apparently these pumps are more of a non high pressure pump - they can flow high HP on non efi systems that dont require alot of pressure.

So for me walbro will make a nice pre pump for the 044

Tomei pump for me as already stated - $340 delivered from Greenline.

Didn't want the Walbro as too many experienced people have had issues with them.

Bosche was looking OK but for $230ish, i'd rather pay the extra $110 and get i higher powered, direct fit replacement.

Considering it's made to fit with rubber seals on the bracket, it should run silent to.

This from nengun site : 248 L/h (Standard 136 L\h)

That's nearly double !

Installed a Walbro the other day, not difficult at all when compared with the mucking around required to install a Bosch pump.

With regards to the pumps having problems, any good workshop should tell you the stock wiring won't really do for this pump. I gave mine a good ground and it works fine, though it's not being pushed with just over 200rwkW.

Although to be honest, the only reason i didn't get a Tomei/Nismo pump is i couldn't wait a few weeks for them to arrive (stock pump failing)..

[turbs33]

govich, you say you gave your pump a good ground. Is it neccessary to run a positive feed str8 from the battery to the pump via a relay to get the correct voltage to the pump?

[govich]

The guys at Unique Autosports didn't think it necessary for my power level. Probably when pushing harder yeah. If you run a direct feed the pump will be pumping it's hardest all the time though.

I can't really comment on walbro vs tomei, as I'm not a skyline specialist but with the walbro pumps as was already stated you can get a kit for it.

There are 2 types of walbro pumps, the GSS341 and the GSS341HP - High Pressure. The standard pumps do not handle high pressure very well, rather than explain, here's a graph that shows the difference:

The walbros are extensively used in the USA with high power Supra's where they run multiples for higher HP applications without any issue. Personally I like the idea of a high pressure 255lph pump with fitting kit for a cheap price, I just finished doing a group buy on the supraforums for $165 for a direct fit kit delivered, you can't really beat the price compared to other pumps.

[LatinR33]

Personally I dont base my decision on price. I prefer quality over budget.

[gts-4 dreamer]

when its pheasable yes

[MANWHORE]

walbro pumps are rated at 255 L/hour, but in tests, at the voltages our pumps run (not at like 16-17 volts) and at the pressures we run, flow is no where around that.

Govic, for the stock turbo, pretty much any pump will do. We're going for more power.

Jase, looks like i'll be going for the tomei too.

Food for thought for you guys - the nismo and tomei pumps are both top notch products. However, which one is better, flows more, cheaper etc Now that's a fun one
