Since fitting the TD5 the performance has been a bit flat at higher revs. While this has been good for fuel consumption figures it’s been a bit annoying. I rigged up a makeshift fuel pressure gauge today using an oil pressure gauge and sender.
Turns out we were only getting 20 psi at the rail, the TD5 is supposed to run at more like 65/70 psi at the rail. I replaced the pickup in the tank with a 300TDi version and it’s transformed the vehicle. A good constant 70 psi at the rail and it shows in the performance. Were it not for the diesel rattle you’d almost think the V8 was back.
Still need to sort the exhaust out though as it’s still running with the “temporary” one I hooked up using bits of the V8 system.
