Fuel tank and delivery

Update

Update - Never say die.

I had been reading up on the use of Citric acid as a rust remover and after some success with a few other parts I thought I’d try with this tank. I poured in about 2 gal mixed with about 1 cup of citric acid powder. I also tossed in a large handful of roofing nails (best) and some other parts (not a great idea) to scrape the tank when agitated, hopefully helping to remove any rust. This physical abrasion/disturbance of the surface proved to be necessary. After some experimentation, I was able to get a pretty decent result and I am able to reuse the fuel tank.

Getting started

I was thrilled to be able to remove the fuel tank with ease, and was hopeful that the surface rust on the exterior could be addressed and the tank reused - a few bucks saved. When drained of the last of its 2-3 gal of very old fuel the extensive internal rust and gunk became evident. the level sender was removed and found to be rusted and seized…. A new tank might be a good investment.

Front End Fact Find

June 15 - confirmed that the chassis is not bent! Plumb bob and chalk lines. See section R page 18 of the Bentley manual for dimensions and method. Update June 12 - more photos of frame Update - Obvious accident damage and clearly the frame horns are not as they should be. Measurement and verification required. The photo below is rather telling. The horns should be 12” apart (11” between the flanges), parallel to the car’s centreline and level and straight with respect to its the frame rail. I am not certain precisely how far each horn should extend from the crossmember. I will assume but should verify that the rad uprights are at 90deg to the horn, and should verify the height of the rad support above the horn. the threaded bosses for the grill shroud (2 in each horn, 3 in each rad upright) are the most critical location points with respect to hood alignment, as these locate the front end assembly. Straight edge clamped to frame rai...

Engine teardown and reassembly

Miguela's seized engine could not be freed in situ. After weeks of soaking, rolling etc I could not get it to budge and resigned myself to the teardown I had suspected was inevitable. The odometer reads 49000 miles. The "12CD" series engine is original to the car, and it does not appear to have been opened in the past, though it does have a copper-faced head gasket which may not be original. Some of the photos also show the light green paint colour that is particular to this series of engines. They are rare and particularly fast as a result. Ease of access is facilitated by the absence of any front end sheet metal. After more hardened mud and grease were removed, the starter, generator, induction and cylinder head were removed. The engine and gearbox were then unbolted and removed. While lifting the engine alone was possible with a helper, an engine hoist will be required for reassembly as the gearbox and engine will be ...
