Fuel Pump... Rebuild or Replace?

Hello everyone! New to the forum. Glad I found this awesome resource. I got a 98 Evinrude 115hp V4. I had planned on getting a rebuild kit for my fuel pump, but while shopping around I found an aftermarket fuel pump for less. $20 vs $15. I figure at that price I can afford to replace the fuel pump every season. Much easier to bolt one on vs having to rebuild one. Just wondering what everyone else does.

Thanks
Jason
 
Factory pumps are very good quality.-----Not sure why you would want to rely on a cheap pump.------How did you decide that pump should be replaced every season.-----How much fuel do you use in one season ?-----Do you do any other trouble shooting ?

I would be surprised if the quality of the rebuild kits for the factory pumps are any better than the parts in the cheap pumps. They're probably all made in China.

I just bought the boat used and have been doing some preventative maintenance. Noticed there was a lot of fuel residue around the pump area and that's what prompted me to service the fuel pump. Otherwise the engine starts and runs great. Maybe it's overkill, but I feel better having a new pump. I know it's cheap, but that's why I don't mind changing it out every season.
 
BTW, my personal motor is 35 years old (1984), and the fuel pump has never been touched. Yeah, I know, now that I said that, it may conk out next time out.

I assume your VRO system has been eliminated and you're now pre-mixing oil in your fuel? There's no way you've found a new VRO fuel pump (or rebuild kit), OEM or aftermarket, for anywhere near $15.

If you're engine has been converted you most likely have a fuel pump off a 112SPL engine like this for $91:

The aftermarket Sierra pump is $61:

Rebuild kits are $21 for OEM and $17 for Sierra:

I'm with Fdrgator, there is no reason to rebuild a fuel pump every year. My engine is a '96 and I'm still running the original VRO. Teh black gunk you describe is possibly a hose leak or the carbs overfilling and spilling back through the throats when the engine is tilted up.
 
I have a non VRO pump. This is the one I got. 4.5 star reviews LOL!

Even cheaper than I remembered. LOL You guys are giving me second thoughts now. Perhaps I should just keep this as a spare just in case my OEM fails?
 
These pumps are elegantly simple.-----Most of them are replaced in good condition.-----Done as a " hope this fixes it " and it is cheaper than a hr at the big repair shops.-----Trouble shooting has / is becoming a thing of the past !

I get what you’re saying. If it ain’t broke don’t fix. But most likely if it’s going to fail it will fail when I’m on the water and that’s what I would like to avoid. Should I wait until my telltale stops peeing water before replacing the impeller? Just sayin.
 
If your fuel pump quits the motor stops with no damage done and you have a spare pump on your hose.-------If waterpump is not providing full water supply and pressure you damage ( big $$$ ) your motor.-----Save your fuel pump money and use it to install a new impeller every 3 years !! ----Where I did my boating ( big, big lake ) I used twin motors.--------When I am on a small lake one motor , even a 63 model is fine.
 
Thanks for all the input everyone! I think I’ll switch out my pump and keep the old one as backup. I’ll let y’all know how the cheapie operates.

The pump has a diaphragm and uses oscillating pressure from the crankcase and lower cylinder to pump fuel. What’s your point? Plastic cracks and rubber seals dry up. For The low cost of $11.99 I don’t mind having a fresh new fuel pump every season as preventative maintenance. To each his own.
