Gen3 Fuel Tank Removal/Replacement?

CrunchyAdams82 · Post by **CrunchyAdams82** » Tue Aug 13, 2013 8:58 am

I've been thinking that at some point I'd like to have my fuel tank out & either replace it for a new one, or just clean it out to remove the 23 years worth of jobby that will have inevitably built up!

I would hope this will help the car run a bit smoother, prevent filters & injectors clogging up as fast, & support reliability & longevity of the engine.

But how easily can this be done? Is it a case that the axle needs to be dropped? I really don't know..

There will be some really corroded straps involved - that's for sure. If you just want to flush it, there is a drain bolt on the bottom of Honda fuel tanks.

Is that so..

Would that be enough to get all the crap out of there though do you think?

I would hazard a guess that the inside of your fuel tank will be by far the cleanest part of your entire car.

The tank that I took off my 1967 Anglia last year, which had 9 year old petrol still in the bottom, was as clean as a whistle inside.

I seriously doubt there's any "crap" in the fuel tank at all.

I'd still like to check you know.

Just to be sure it's all as clean as it can be, ready for when I drop the H22 in there.

Cos I'm gonna have to start using Nitro+, so want to make sure it's not being mixed with any old sludge & general nastiness.

@NafemanNathan or @RattyMcClelland, you know anything about this?

Nope

Not even looked at the underside of mine yet.

If you were to locate the drain plug and then jack the car up so that there's an actual run towards the drain hole. Disconnect the fuel line and cap the outlet/return/breather inlets, and then blast some flush into the tank via the filler neck using a pressurized weed-killer sprayer thingy, that might dislodge any silt that may be in there. But I wouldn't expect much at all as Garry says. Probably thinking a bit too hard about several areas here bud

Oh, ok. I always assumed there would be a build up of deposits in there. As fuel has a lot of contaminants in it, & degrades over time.

Would be interesting to see though, surely? If it's easy enough.

@tramroadmotors, I assume you've removed a fuel tank or two in your time.

What are your general findings in such situations?

Should be pretty straight forward to remove Andy (Corroded fixings aside). Get under the car and have a look
