Gauge to check fuel pressure on 1999V70

Post by wooshuck » Mon May 13, 2019 2:30 pm

I am helping to diagnose the no-start problem of my friend's 1999 V70 wagon.

It ran previously and just died one day, never to run again.

As soon as I figure out all the directions from the Volvo DICE scanner and software I bought I'll use that but in the mean time I want to do some other checks.

There's a Schrader valve that indicates fuel pressure on the fuel rail. The fuel connection is more like a tire connection than anything else.

Where can I find a fitting that nooks up to that and might be connected to a pressure gauge?

Your local auto parts store (Rock, Oreillys, Advance, Pep Boys) will loan you a fuel pressure gauge with fittings that will work on that Schrader valve

In a pinch, a 99 cent tire pressure gauge can be used (and then thrown away).

'98 S70 T5M - 270,000+mi - forever a project
'99 S70 "AWD" - 218,000+mi - project
