ajh Posted August 10, 2009 Share Posted August 10, 2009 Is there a good way to tap a fuel pressure gauge into the high-pressure portion of the 200TDI distribution pump? Adding one to the low pressure side is easy enough. I keep seeing low-fuel-pressure as a possible cause for performance issues so want to proactively fit some gauges to be able to see if one of the pumps starts to die.

western Posted August 10, 2009 Share Posted August 10, 2009 on the fuel lift pipe side you'll need a gauge that is able to read 42 to 55 Kpa on the injection pump peak operating pressure is 650 bar the injectors are 2 stage type & work at stage 1 opening/working/initial opening pressure of 200 bar stage 2 working pressure of 280 bar so some big numbers & very high pressures, don't think I would like a gauge running at those pressures within the cab.

ajh Posted August 10, 2009 Author Share Posted August 10, 2009 If mechanical they need to be engine bay mounted but autometer has a line of electronic sender fuel pressure gauges now that while expensive are fine for dash mounting. One is 0-15psi the other 0-100psi (posting from phone so not sure the metric equiv) we typically use kph, celcius and psi here for some odd reason. What I am more wondering is if there is a port on the distribution pump to fit the sender reasonably or would. Need to tee off one of the injector lines.

Retroanaconda Posted August 10, 2009 Share Posted August 10, 2009 Well 200 bar is nearly 3,000 psi so you'd need a pretty hefty gauge.... Quote Link to comment Share on other sites More sharing options...

ajh Posted August 11, 2009 Author Share Posted August 11, 2009 OK, so lift-pump only it is Seem seems to be something worth having, along with the electric back-up pump. Quote Link to comment Share on other sites More sharing options...
