Hey Guyz, i am planning on picking up an Walbro fuel pump for my car and just wanted to know which is the one i should buy for my car which is bolt on and fits fine to an R34 GTT, i am a bit confused between the GSS 341 and the GSS 342??

Thanks Guyz!!

I'd only Get a Nismo/Tomei on an S14/S15/R33/R34. The Warlbro sock is on a 90 degree andgle but it needs to be 45. Same prob with a Bosch 040. Mounts on a 45 degree angle so won't pick up low fuel levels well at all.

I HATE spending money I don't have to but I do strongly think it's necessary unless U wanna only use 3/4 of your fuel tank.

Isn't the difference between 341 and 342 whether the inlet is on the right or left side?

As far as running out of petrol? I've never had an issue with my walbro (342). I installed it myself on a empty tank that the needle was at the line (not on the line - level with the empty line) - no issue from very first prime! I've been below the line several times. Filled with 55L and still didn't have problems.

who is dumb enough to "GIVE" it some on a windy hilly road with it dead on empty? cmon be realistic here.. also im the same as simpletool, installed walbro pump and i have no dramas running it right down near the empty line

Ok so from the above posts im gathering that both the GSS 341 and the GSS 342 will fit, any differences in fitting or using them?

Im not buying it from Australia thats why i want to know exact details before i buy it... So the 341 or 342??

A walbro is perfect for an S13 or R32 because the bracket is vertical. S14/R33 and later go on a 45 degree angle riiiiight down in there, causing the sock to angle 45 degrees upward. I guess u could work something out to make the sock sit a bit flatter.

Yeah this, I got a 342 in my rb20det hr31 and any less than 1/4 a tank if you booted it around a corner it would fuel starve, not an issue with a stock pump or other pumps, you can probably modify the sock but it was a massive pain in the ass for me.

My R33 has a vertical bracket.

Like I said 341. if you specify the vehicle you can get the most appropriate fitting kit.

you know the r33 sock of the stock fuel pump fits directly onto the walbro.

I've had a walbro in two of my 33's and an s14, each time I've used the factory sock as it's longer and sits at the right angle.

Just some food for though ;)

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked... HTH
    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
