Fuel filter bowl for Toyota 2007 VDJ79 V8

Hi Mark, this is not a common problem, but my Brother had this problem on his and he found it was caused by someone over tightening it after service. I hope this helps.

Mark,

Happen to be baby-sitting, or maybe that should be "ute-sitting", an 07 ute at the moment. Just had a look at it, and wonder, with the 2nd battery in place, whether it mightn't get extra hot, being not far above the turbo?

Have always been suspicious of these "white plastic" fittings, and their longevity. We always kept a spare for the filters used on the earlier models, because if it broke, you'd be pretty much stranded. Or at least need some "knead-It" or "Minute mend".

Dunno about the acid factor? Might have some bearing on it? Good to see you got home before it broke!!!

Bob.

there has been a bitof discussion and several incidences reported on LCOOLl forum and battery acid from 2nd battery instals seems to be the culprit.
does your vehicle have a non sealed type of battery ?
cheers

thanks for the comments.
I've done the bleeding obvious and dumped some acid on the bowl and also the plastic. It stained the steel similar to the other side, but the acid just ran off the plastic. Certainly over-tightening the tap could explain the splits, (but jeez you'd have to use pliers!) but not the curved cracks at the other end of the 'pipe'. The 'dirty' parts on the plastic are rough and appear to have been pickled. There is no evidence of any acid spillage on the mudguard below. Both batteries are very well sealed and I've never seen the tops wet (with acid). Puzzling!
By the way, does anyone know why the unit is screwed together with allan key bolts as opposed to normal hex styel bolts?
