496 cool fuel bypass
 

Hi , i have a question i have a fastech 312 with 496/s cool fuel mounted to bottom of engine, if i had to ever replace them it would be a disaster it appears, would possibly have to pull a motor. dont wanna deal with that is there a way i can by pass that by just installing electric fuel pumps that i can mount near the halon system?

You can run aftermarket pumps, but you'll also need to add a fuel cooler. The plumbing can get more involved than it's worth especially in a tight compartment with twins.

Actually, you could plumb an aftermarket pump and send the return back the tank (the tank acts as the cooler vs the cold water tube).

any pics or any suggestions on what to get? , seems confusing but man if one of those pumps craps out i dont know how ill get at it. bob

I'm running an Aeromotive marine A1000 pump with their A1000 regulator.

What year 496? Gen 2 or 3 cool fuel?

gen 2 just a PITA to get to

It will probably never fail as long as you winterize it properly. Don't just rely on the little air pump thingy and stop worrying about a problem that doesn't exist. ;)

496 not the greatest motors my 02! Good luck

Why?
 

I agree with others that you are chasing a problem that doesn't currently exist. Even if you "bypass" the cool fuels, you still have to get to them to pull the fuel lines, no?

ok thanks , i am having some trouble, thought they might be the issue, thats why i asked.

thanks theyre already in the boat though , not much i can do about it now.

What about removing the low pressure line where it enters the spin on fuel filter THAT COMES FROM THE COOL FUEL PUMP. On the filter its a std 1/4" npt fitting. Just extend the hose to the tank or fill hose. And put in a 1/4npt male pipe plug in the filter inlet you took the hose out of. I haven't done it but maybe others on here have.

My only concern is that in the 95 deg heat on the gulf coast, will the gas in the tank slowly heat up enough after 9 hours on the water, to cause vapor lock. If it does then you have worse issues. No colder fuel left anywhere to pull from.

Has anyone experienced this whole tank heat up issue especially when your running with a low amount of gas in the tank it will heat up quicker.
