  • Fuel pump replacement aftermarket indmar 556014

    So if you are cheap like me, u can do the 500$ conversion for 100$. All I did was order the carter p5000 from summit racing.   https://m.summitracing.com/parts/crt-p5000

    Then I removed return to pump line from the bracket and plugged it with 7/16 x24 fitting plug. I spliced a new connection and put it back together and it's been good.

    So the original was discontinued right?  The new one doesn't have a return line and you bought the "generic" version, instead of Indmar for almost $400 cheaper?  Nice.  I think this trick applies to more boats than you think.

    Yes the original pump was discontinued and they sell a conversion.  The conversion was still being manufactured when I replaced mine.   I would have been down last summer for 3+weeks so I researched the pumps specifics.  The p5000 was same psi and flow, from information I could find, and I figured as long as the pressure regulator could dump back to tank I'd be ok.

    So the return line goes to the pump and not the tank?  For some reason I thought it dumped back into the tank...good to know this works.  I've been keeping an eye on fuel pumps since it seems like it happens all the time to boats of this age.

    I know this thread is old, but being someone with experience in automotive racing and boating, I started researching the fuel pump in Indmar’s s495117 conversion kit and found some with the pierburg brand pump and some kits without. They all had the same part number, but the kit that doesn’t use the pierburg brand pump uses the Walbro gsl392 pump. The number is on the pump Indmar sales for over $300, but walbro sales it for $98. Fuel pump pt# gsl392, fitting pt# 128-3041, Order the copper sealing washers with the fitting, $ .99 each. Just have to check the box. Your not supposed to run anything smaller than a 30 micron filter pre pump, but no matter where I look all I can find for our 1/2” fuel lines is 10 micron or 149 micron. I have used the 10 micron wix 33299, or Napa 3299 for 5 years now with no issues. This is my first post and I don’t know if links are allowed, so if it gets deleted I understand. But here is the link to the manufacturers online store for the fuel pump. https://walbrofuelpumps.com/walbro-gsl392-inline-fuel-255lph-pump.html

    Good catch on that pump! 

    Me too on the filter, 3 years now on a 10 micron filter and absolutely no issues, but then again the Yahama spin-on filter I use is 10 micron but also 90gph capable.  Just a hunch but I'm guessing that the restriction was for the smaller filters being used and could hinder flow if slightly clogged and/or at high demand and subsequently induce vapor lock on start?  Either way, not an issue at all for me now that I added the secondary fuel pump.
