View Full Version : How hard to change a fuel pump on 01 Predator?
04-23-2007, 02:00 PM
I have replaced 3 fuel pumps since 2002 (even though I always keep the fuel level over 1/2 tank). My boat is acting a little strange (it died twice over the weekend - but restarted after a few minutes). It might be water in the tank - or the pump going again. I might buy a spare and change it out myself if it goes (I'm sure it will eventually). I am relatively good with overall maintenance but am by no means a mechanic. Also, any special tools involved? Thanks!!

Nuthin? Anyone have any insight??

I had a thread on it last year, it wasn't tough, you just needed the special tool to remove the line from the pump
the tool is $15 on up, depending on the quality ... just go to your local auto parts place and ask about a fuel line disconnect tool ... or google it ... in our case the local MC dealer let us borrow their tool and we replaced it up at the water ... if you think it is the pump you may want to check the fuel pressure on the fuel rail to verify ... sorry man, 3 pumps really sucks ... gotta love those carter fuel pumps:(

Next question - how to check the fuel pressure?? That would be really helpful - especially since I am guessing that it would tell me the pump is on it's way out...

somebody more mechanically inclined please chime in ... on the top of your engine the high pressure line from your pump connects to the fuel rail ... the fuel rail has a schrader valve (like the one for pumping up your bike tires, car tires, inner tubes, etc ...) the fuel pressure guage simply threads on to the schrader valve and tells you how much pressure is in the line ... in our case there was zero pressure (we held a clean rag over the valve and depressed the needle and there was no fuel coming out - hence no fuel pressure) so we didn't even need a guage ... if you have a picture of the top of your engine I can point it out to you, but the boat is in storage and I don't have a good picture ... spin the fuel pressure guage on, turn the key to the on position to where the fuel pump should cycle (don't need to crank the engine over - so you can just test it in your garage if you want)

this is not an MC/Indmar fuel rail, but just and example of what I am talking about when I say "fuel rail" - and I guess I keep misspelling schrader ...

You may be able to borrow a gauge from someone...otherwise for $30-40 bucks you can purchase a fuel pressure gauge from NAPA or other parts store. One end of the gauge screws onto the schraeder valve on the fuel rail; turn on the key on but do not start the engine (read pressure), and then start the engine (read pressure again). Not sure what the reading should be on a "good" pump, but you may find it here from another thread. It might also be listed in your owners manual. Good luck -

tool used to take off fuel line from pump - I'm not sure of which size gets used ... someone could tell you the particular size, you could buy a kit, or buy a universal style

fuel pressure guage

You guys are good - I am going to get a guage to start and go from there. When I find out the right fuel pressure - I will post it here for the group.
