Lots of good information on replacing the fuel pump in the "Fuel pump 101" thread
The aftermarket fuel pumps have 5/16 inch barbs on the output nipple AFAIK while the fuel pressure regulator that the other end of the hose attaches to is 1/4 inch. The hose is full pressure coming out of the pump...how does attaching the 5/16 inch hose to a 1/4 inch nipple work out?

Yeah I remember someone doing the swap and ended up tearing the hose before they got it on the replacement pump.

Good find on the tubing. It had been elusive.
My replacement pump from 4 years ago is still going strong!

I seem to remember someone else posted where they used a short segment of brass tubing as a shim and that clamping it down, it worked fine.

I have:

Pump Carter P74122 (comes with screw tightening hose clamps)
Allen Wrench / not sure the size off hand(I check it and put it in the box)
EFI fuel line removal tool (got it from napa)
New fuel filter(I'll replace the old one when the pump fails)
My normal on board tool box(vise grips, screw drivers, pliers, ear clamp pliers)
I ordered the flex hose that was posted above
Need to get some ear clamps, 1/4 3/8 5/16 and 1/2 inch (these because that's what's used on the pump now)

The ear clamp pliers are needed for ear clamps. Wakemakers.com sells a pair for dirt cheap.

Hey all,

Great tips and comments. My '06 X45 with the 8.1 went out at about 300hrs with no signs of failure before it just died. Of course, it died as I was pulling away from my dock to go put it on the trailer for a family vacation. After many phone calls and digging through this site I was able to locate the right pump locally at OReily's. I tried my local MC dealer but they wanted $600 to replace the pump and didn't have one in stock. I pulled the pump, called the local auto parts store and picked one up for 80 bucks... and a spare for another 80.

Lessons learned:
- Never run the tank below 1/4 full - dealer recommended
- Always check for universal replacement part before buying from dealer (I'd rather spend my money with the dealer on cooler stuff than fuel pumps)
- Carry a spare to be safe
- Keep the tools referenced above in the boat at all times - that fuel line removal tool makes quick work of pulling hoses.
- Keep a calm head in the face of huge frustration. The failed pump only set me back a few hours...yeah, in the moment I was ready to explode

>>>>>>>NOPE!!! Mine on my 08 XStar with the 400 hp motor just went out this past weekend...Easy fix. Took less than an hour. Used same part as stated (Airtech E2044) and everything has worked fine since.

TO add to that....On my 08 I only needed to replace the pump itself...All hoses etc fit back perfectly. Didn't need to buy anything else except the small tool used to remove a fuel line.

Beg4wake I assume you got tool at any parts store by asking for ???
Also is everyone using what you got or switching to a flex hose mentioned on this board?
