I think you sound on track. One thing to check maybe the feed wire to the IP. Maxfax had some intermittant trouble from his 12v supply. The wire looked fine but it wasn't. That is if your ignition isn't the problem.

Is this the car that gets "other fuels" rather than diesel?  I haven't heard that feeding them differently shortens the life of the pumps.  Are some less able to do WVO, SVO, WMO or diesel with tons of additives?

Slapping the tank around will be reported the treat tanks kindy police.

diesel cars do not have an in tank pump natively..

my car used to be equipped with a digifant 1.8L 8v engine..

now it had a 1.6 diesel..

so, yes, it does have other fuels than what its designed for.. and i havent dumped anything but diesel or stove oil in my diesels for years now.. they are capable of other fuels, even pure WMO.. i used to run some WMO in my first rabbit, but not anymore..

i swear ive seen people do conversions on these mk2s, leave the pow pressure pump in the tank, and have reported no issues..

so im thinking that if my pump is bad, its been bad for a while.. may even be the reason i never could get the digi engine running right..

So if the pump is both bad and not needed did you just delete it?  Seems silly to have a known failed part in line when you don't really need it.

I think your exchange of engines to the diesel is on the postive side of the equation.  But isn't it how it always goes, find the "real problem" years or months done the line.

the in-tank pump is gone.

deleted.

 never to give me troubles again.. rigged up the lift pump out of my rabbit under the car where the high pressure pump/reservoir was.. it never gave me a single issue ever, so thats good enough for me. its a bit noisy, but i can cure that with rubber isolators..

I love electric lift pumps..

I totally drained my fuel system to do a re seal on the pump and a new filter. Electric filter made the priming take a minute of absolutely zero hassle :D.
