Hello all, long time no-postie–but I have an interesting question.
My high pressure fuel pump in my Johnsuzki 140 failed, and I ordered a replacement (not for the whole fuel/vap separator, just the pump inside). Looking at it, and perusing pictures on the internet, I’m convinced that it is the same thing as the fuel pump just about every Japanese automobile manufacturer has used for the past several years. I know four-stroke motors, especially from Suzuki and Honda borrow heavily on automotive technology. The difference in the price is staggering. $290 for the BRP branded replacement pump; $30-50 for an automotive one. My question is–has anyone, with any degree of success, looked into using the “car” version of parts on these motors? Is there any resource to cross reference the part numbers? I’m tempted to take my $290 pump, go to Autozone, and match it with whatever they have on the shelf to give it a try; it’s worth $250 to me. I do not mind spending money on the boat to have it proper, but if there’s an opportunity to save some serious $$$ for exactly the same parts, I’m gonna give it a shot.
Do you think its just a walbro or carter pump? 1 main thing to look for if the dimensions are identical is some are internally pressure regulated and others not.
I am a diy guy and am a professional mechanic but honestly I would just pony up the extra bucks and get the direct replacement. Nothing hurts more than paying 100$ for a sticker swap but with how particular outboards are with fuel requirements, I don’t think I would chance it unless I could get a definitive answer from a reputable source.
It’s externally regulated; and the case is very similar to a Walbro 255 that is spec’d for some Japanese cars. One question I do have–the shop manual describes the ECU controls the duty cycle of the pump by turning the power on and off based on fuel demand (it’s a 1000 Hz pulse cycle). I’ve never taken the time to research whether cars have a similar type control system, or just rely on the regulator to dump the excess to the return? This one does both, apparently.
I’d just be so nice if there was some way to tell “Yeah, the 90-140 Suzuki uses the same fuel pump from the 1999 Suzuki esteem” or something…
I have a Suzuki DT 140 that had the same issue. A guy in California had a thread on a website that listed the correct fuel pump to purchase. I’ve had it for 3 years trouble free. 80.00 bucks instead of 540.00. I’ll look and see If I cant find the website for ya
I could use the extra $$ to replace the idle air control valve in my car that went out yesterday. Apparently I have bad fuel injection juju these days…
Rebel, keep us informed on what you do. I am curious now. My evinrude has a carter pump on it and I may try to source an automotive one for a spare. I did just spend the 480$ for it last year though but these things can go at any time.
the ECU controls ground to the pump
pump doesn’t care what it goes into, vst or fuel tank
most Japanese manufacturers try to use stock parts to keep cost down
same thing with bearings, seals, etc
very few are custom designed for that application
problem is finding the right one.
pressure regulator will handle excess pressure, and most of those motors need less than 30psi
Received the new fuel pump I ordered. It’s in a SGP Suzuki parts box, with a big “BRP” sticker on it. Funny thing is, the price for the BRP pump was about $50 less than the Suzuki pump from the same website.
Anyhoo… the only markings on the pump is a Mitsubishi logo with an “A” beside it, then “UC-T33” on the pump head. On the inlet side there is a “31” inside a circle.
A quick googling hardly reveals anything, other than it may be the same pump some year Mitsubishi outlander; which themselves range from $50-$350. More popular searches are for “UC-T30” (apparently a Suzuki GSX-R pump) and a “UC-T35” (apparently a 4-wheeler or UTV pump). Very little on UC-t33. So, it was a valiant effort, but I don’t seem to be easily stumbling on a automotive direct replacement for a fraction on the price.
Replaced the pump today; turns out the old one was a UC-T30; all the same with a slightly different pigtail on it. It seems there is much more info online for those, and there is plenty of info out there on what it cross references to–carter, airtex, and walbro. So, if there is a next time, that’s what I’ll go to!
Now, the boat runs, but my intake manifold gasket is leaking… back off with the manifold… always something…
