fuel pump replacement preemptive strike

[scottb7]

Anyone think about replacing fuel pump(s) before they go out??

Yep it would be few hundred but maybe worth it.

For those that have had to replace, which one went out? Low pressure is outside the cell, and the high pressure is in. So far I only know of one data point and that is a guy on this site that replaced low as it went out at 900 hours.

Thoughts? Would like to have more data about which one went out and when!

I am that guy.
When my fuel pump went out, it was in the Spring pretty much the first run of the year, and that was the only year I did not add fuel stablizer to the gas in the previous Fall.
The pump quit moving fuel, but still ran. Later, I cleaned it out, and it now moves fuel just fine.
I also put Sta-Bil in my fuel every year. I have not had a fuel pump problem since.

Find non-ethanol gas if you can....IMO worth the extra cost. Had a 05' SAN and after two years (about 300 hrs) the fuel pump out of the canister was completely corroded like it had been exposed to salt. (it was a 100% fresh water boat). Also had a 09 SAN/343 and the low pressure pump went at about 200 hrs... PCM stepped up and warrantied the 05 (it was just out of warranty) and of course the 09 was warrantied.

Why? Its not a Mastercraft!

I think it's the fuel killing the pumps because its a nice little bowl for the stuff to sit in all winter long. We saw a lot of bad low pressure pumps last year but not so many this year (maybe we fixed them all by now haha). If anything I would buy a spare and carry it along so you can get all of the useful life out of the current pump.

Zach, so mostly low pressure pump's are the ones to go out? That is the one outside on outside of the fuel cell, right?

I never had to replace the low pressure fuel pump on my 2000 Sport, but I always carried a spare . . . especially when on vacation.

Mine was going 2 years ago with 1230 hours on my 2000. It would occasionally trip the breaker. It cost me the first time to have a mechanic find it was the cause. I ordered one and replaced it. No problems since.

[scottb7]

Rick, it was the low pressure that sent out or high?

Not trying to answer for Zach..........but yes, it is the one outside.

[Zach@n3]

Thanks Matt! Yes Scott, the "acorn" external low pressure Carter fuel pump is the most common failure. The later Fcc boats (08- on I think) aren't effected by this (with the external pump on the Fcc) but time will tell on those as they aren't that old yet!! So if you have the pump on the Fcc I would say don't buy a spare but if you have the "acorn" style below and outside the Fcc then you might be served to carry a spare and the proper tools to swap it out.

Quinner's pump on his 206 went bad up at the Green Lake reunion this summer. I played with it for a few minutes and found it would if you primed the pump with the key pad 5 times or so. Grabbed a test light to verify power was reaching the pump (it was) and the only part stupid me didn't bring to the show was a lp fuel pump ha. We removed the FCC when the boat died to verify that there was not enough fuel reaching the canister and there wasn't. There was a debunked Nautique dealer less than an hour away so he picked up the part and Joe tossed it on the boat and away he went for the rest of the weekend.

"minor" hijack here, is it recommended to replace the fuel filter every year? I can say with certainty that the one on my boat has not been changed, I did not change it last spring, boat probably has 150 hours on it now. Probably a question that has been answered many times but of all the reading I have done on her the last year I don't recall seeing a recommendation.

[Quinner]

Not all CC's came from the factory with an inline filter before the Low Pressure Pump, the FCC filter is after the pump. When we yanked the LPP on mine and later took it apart there was some garbage in it. If you don't have an inline filter before the LPP might be a good idea to add one assuming that will not create a problem. Manual should tell you, believe it calls for an FCC filter change annually or at 100 hr intervals. As far as the Excal LPP, mine did go out on vacation although it could not have happened at a better time/place as Zach helped me diagnose and then he along with TRBenj, Joe, Lewy and Gundriver (thanks again guys!!), we had it changed out in no time. Took longer to find and get the part then the diagnoses and replacement, lol. Keeping a spare on hand as Scott mentioned is a great idea, Lewy also mentioned the LP Pump looked exactly like one he had replaced in an automotive app for a fraction of the cost??

[Zach@n3]

Jason, We "recommend" to customers every other year on the FCC but our premium winterization package is all inclusive and makes it a no brainer to do it every year so basically all of the boats we service regularly get it every year. I will probably observe ever other on my dad's GT-40.

[jsta281]

I'll put that on the list for next spring
