My trusty 1992 UK spec 1.8 L-series 4x4 Estate failed it's MOT last week due to a leaking petrol tank. I've removed the tank today and have found very small leaks in the rear seam and, in addition, two of the outlet pipes sheared off when I disconected their rubber pipes - they were really rusty. Here's my question I hope you can help me wirth:
At the front of the tank it's the outlet that has sheared off while the return is OK.
At the side near the filler it is the small breather (?) that has sheared while the other pipe connection (what is it?) is OK
What I need to know is, are there one-way valves built into these tubes within the tank. There was a little bit of fuel still left in the tank when I removed it and both the unbroken pipes would not drain fuel when the tank was tipped while the broken pipes pissed it out. I intend to weld on some new pipes to replace the old ones and would normally clear the others with some compressed air but, if there are valves inside, I don't want to damage them. Further, would a SLOSH tank sealant mess them up? My Haynes is no use at all on this subject and was completely incorrect concerning tank removal and does not tell me what the small tubes at the side actually do.
Best wishes all,
