Aye o the preparation for a lot of fuel coming out the tank drains. Been there, done that… thought I was prepared. I was not!!!
Aye, that the only way to be really sure that all the crud is out, is via the lower drains… the large one is better. I got that, although my target was the smaller one. and, to my surprise, the tanks were quite clean!!!
The hard rubber plugs in the valance were ruined in the endeavor. After considerable thinking, I decided the car was better off wi8thout them. In other areas of the planet, perhaps not.
Only once have I succeeded in siphoning fuel from my SIII. A neat little suction device from HF… Two hoses into a hand pump. Immerse one and pump away.
I’ve another in my shed. Been there for decades. Clever, but it never worked for me. I do get the principle. A length of clear hose. A one way valve at the foot, aka a foot pump. Jab it into the tank, valve first. Then push pull. Much like an ancient butter churn.
Doug’s suggestion as to the use of the car’ pump is intriguing…
My motive was to assure that my fresh fuel system get fresh gas…
