Keep in touch as I get to know this old beast. |
I read about the Dowel Pin issue (and that fix) as well when we first got our Coach last year (w/ 5.7 12V).
When we took our Coach to Cummins NW (Oly) for maintenance and some repairs, I forgot to ask about that to see what they say. We had hoses, belts, filter including that big expensive air filter, chrome tail exhaust pipe replaced, exhaust manifold and turbo replaced. Radiator flush and new fluid, oil change, shocks replaced, parking brake adjusted and overall safety inspection. Probably would have been a good time to do that Dowel Pin fix.
Are you going to do that Dowel Pin fix?

Their doc says:

While the addition of a fuel pressure gauge isn’t necessary on the ‘89-‘98 12-valve engines with the
mechanical fuel delivery pump, we can offer some tips should you want to install a gauge.
