Glenn,
Let me understand:
I changed the Mann filter a few years (i.e., <15 mi.) ago.
Did you mean 15 miles or 15kmiles? and a few year ago
Do you mean the spin off filter? If so, you should replace it....
Take the old one off, pour off the diesel fuel and throw it out.
With new filter, fill it with Diesel Purge then reinstall. Car will
start easily running on Diesel Purge.
Second. How does the in line clear filter look? If it's dirty,
change it out also........ I always used the clear ones so I could
check fuel quality/dirtieness!
Maybe preaching to the choir, but thought I'd throw this out there
anyway.......
Take care,
Chuck
