How To Remove your Fuel Cooler

In this video our shop supervisor Brendan takes us through the process of removing the fuel cooler on the Cummins 6BTA. Watch this supplemental video on the newer 45 degree fuel supply fitting. • 6BTA 5.9 Fuel Cooler R...

Great video.. I was looking at the new location of the fuel supply line fitting installed in video to the take up pump. After actually looking at it on my boat it will be going right in front of the RWP impeller which I thought this was supposed to eliminate and make it easier to replace.

Hmmm. It is in the general vicinity, but we haven't had any complaints that it makes it harder to change the impeller.

fuel line wasnt connected, where does this go?

[@GuzziMikeR]

Great Video - Thank you. Question: I also have a mechanical Pressure gauge (sbmar Kit) hooked to the block. Would it make sense to attach that to the oil line that fed the block in place of the small brass cap?

[@larryfalco4841]

What type of fuel line connects to the fuel return fittings?

[@salvor1]

great video, but you don't cover the obvious question -----why?

[@dsmoll91]

in order to change the impeller you have to remove the fuel cooler every time. for those of us that don't need a fuel cooler it's worth getting rid of...

[@Hitman-ds1ei]

Not sure about removing for all HP ratings as fuel temp becomes quite critical at higher HP applications ?

on my 1998 6bta 370 me I have 5 lines to plate and 2 sensors, You kit/video accommodates for 3 lines and 1 sensor. can you advise about the other 2 hoses and sensor? thanks

You had to use a 9/16, 11/16, 13/16, 15/16, 7/8 and a 3/4. I wish manufacturer engineers who use less sizes -over spec if you have to eliminate a size or two or three...make the job easier since the real work is not done on a bench or platform but in a small hole of a work area...

In the video and pictures on your website at the end it just shows the fuel line not connected to anything. Do you re-use one of the existing lines to connect the 2 exposed barbed fittings?

[@SeaboardMarineIncVideos]

The supply and return connect to the tank in the boat. You need to make those lines up custom on the boat and make sure you have fuel filtration on the supply line as well.

[@wilbertxoolturriza5479]

the question is why do you remove the fuel cooler? why?

[@SeaboardMarineIncVideos]

The high number of potential failure points outweigh the benefits by far. The real question for most is why not remove the fuel cooler?

[@Carolina-cb7zt]

Besides less failure points, it makes impeller changes a lot easier. If you lose an impeller offshore you will be glad those hoses are out of the way while pitching around in a hot engine bay. That was not supposed to rhyme lol

[@salvor1]

ok, I just read about it.
