Hi guys,

Couple of interesting alternatives are available atm to the usual Walbro GSS-341/Bosch 040 options:

AEROMOTIVE 340LPH 340 LPH 90PSI HIGH FLOW FUEL PUMP

These are pretty new I think, looks physically almost identical to the Walbro, claimed 340LPH flow, available on (ebay) here:

http://cgi.ebay.com/...n#ht_4609wt_933

some Supra-related info:

http://www.supraforu...w-charts-review

...and...

Deatschwerks DW300+

These look promising and cheap at $169 US thereabouts (considering the exchange rate)... claimed 300+ LPH.

http://www.deatschwe...-tank-fuel-pump

Look like the Walbro pump again, no Skyline-specific model fitments listed but here are the physical dimensions:

Anyone used either of these? Anybody have any recommendations? I don't know where fuel pumps are really at these days... everybody still use the Walbros, or...?

cheers

the 040 is too big for the stock setup

same size as stock, easy to install, proven and cheap

One thing about both of these models is that they claim significantly higher flow rates than the walbro (300-340 as to 255) which I believe has poorer flow rate performance unless it's hard-wired anyway (though to be fair probably all pumps do?). Just something to consider...

the main thing to remember is that the c34's don't have a cradle like the skylines but instead have a box that clips to the bottom of the fuel tank

so going any bigger than stock will be a big pain to fit nicely without hacking up the box

I was looking to run one of these but they were twice the price and they also draw twice the current. I came to the conclusion they are great if you cant fit twin Walbro's in, as the twins will flow more at a similar current. Of course not too many people will need a 1000hp ethanol system anyway.

Tom, that plastic box looks very similar to what the m35 has. It may not allow enough fuel to enter the container if you run the larger aeromotive pump as I have found with the twins. Its only a problem at under 1/4 tank.

So lets throw an ace in the pack hear

2x walbros = what..? 510lph?

To burn even 1 full capacity of a walbro you wd need serioisly big inj, running huge duty cycles.... With a tune and car to suit....

Why in gods cock would u need anything more than the quiet, easy to install, cheap, more than enough flowing walbro...:)

because they only flow 255lph at some shitty low fuel pressure

ah just found the chart, they also only flow 255lph with no fuel lines attached, Ill assume the Stag lines are 5/16" same as the Skylines...so try and blow 255lph through a long maccas straw.

please show me how it would be benefitial to have 2x walbros...

stock 25 inj run at 370cc... so all 6 at 100% duty (never come close to that safe) is 2220cc/per min...

1x walbro flows with no lines at 4250cc per min...

even half the flow rate for lines witch would never ever happen... and you could still run your injectors at ~99.6% duty... if someone was stupid enough to run this higher %. they deserve to be kicked in the head lol....

scott upgraded the fuel lines to braided SS , pressure reg, and 1000cc injectors.

hence: beneficial to have teo walbro pumps.. the way its set up is, one pump runs one fuel rail(theres two as v6) so makes if efficient!

1000cc is just the spec of inj....

what sort of duty is he running... all these mods mean nothing more than the amount of fuel the car ACTUALY chews per min...

im not saying what hes done is wrong or right... just wondering why he has done what he has more than anything.

and wouldnt the braided lines flow much better than stock...?

having 6000cc worth of inj

and 8500 worth of fuel suply,

at 100% duty. he has 30% or so too much fuel b4 the lines... leaving him well ahead.

what sort of % would he run?

he maxed out the fuel lines on the last run. with the gtx going in he wanted to be safe so he knows that atleast his fuel system will be able to cope.

i think i recall him saying that he had already made the twin pump setup before he found the problem to be the lines, so he used i9n anyway.

but can definitely see your point.

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
