Fuel Tank - Flushing

Hi All

As you may know from the other posts I have a project - a Ribtec 655.

This has a built in fuel tank (140litres according to others on here) - how would I go about flushing/cleaning it out etc?

Any suggestions welcome!

Cheers!

Sorry to jump on the bandwagon but I will be in the same position in about 2 weeks (8m ribtec), only difference is my tank is diesel. If there is different advice for diesel vs petrol can we get the full picture. Thanks in advance.

Some years ago we had a problem with the build up of crud in the tank on our tornado dive boat,. After cleaning the idle jets out umpteen times on our lovely yam V4 we took the bull by the horns and cut a large hole in the top of the alu tank with a hole saw. I then flushed it out wit endless buckets of hot soapy water. This is after syphoning all or as much of the fuel as I could get out. The crud inside was surprising as well as some water. Droplets. After the final flushing with petrol it was all left to dry and we made a plate with a screw cap to fit on. Not had a problem since, fingers crossed. Dave j

My tank is built into boat and got contaminated through my own doing. It has a 6" round hole on top of tank at rear. I tried flushing with soapy water and pumping it out with a drill pump before I finally removed the inspection hatch. I was amazed how much muck and slime still contaminated the tank. I did same thing, hot soapy water, then pumped it out on an angle to move debris to the last bulkhead I could get too. Then back flushed with hose and sponged all the bits out multiple and multiple times. The baffles collect all sorts, so I used what would ever fit through the holes to scrub every bit I could reach. I doubt I got to even half of it in reality.

Rinse and repeat. Fairy liquid seems to work and I then cleared that it with petrol flushes. Not used it yet mind.

Does the tank have an inspection port for you to access the inside of the tank?

Who cleans car fuel tanks? So why would you clean a RIB tank? Besides, both have fuel filters, which are consumable items.

As in, why would you need to clean a fuel tank? Fuel filters are consumables.
