An '83 DL was our first Volvo and my introduction to fuel injection theory, in 1999. I include a picture for sentiment.

It was the challenge of measuring fuel pressure which first brought me to the Brickboard that year; my question arising from a frustrating search of the auto parts stores for fuel fitting adapters. The Brickboard advice? Get a fuel rail at the junk yard and make the adapter from it. The result:



I think this was prior to Randy's method described in the 7/9 FAQ or I would have used compression fittings.

Anyhow, I remember convicting the FPR of high pressure and no diaphragm leak once I got the gauge connected. There was not anything flowing back to the tank, so the pressure was way high, but not meter-pegging like I later learned the k-jet pumps can do.

The dissected FPR yielded a tiny spring rusted in two. The little BB was rolling around inside too, I remember. At the time, I was satisfied, but now I would love to examine that same FPR again to see why the diaphragm and valve could have closed off the seat so well without the spring and ball, because the later FPRs are not of the same construction.



Great tank for a sixteen-year-old!
