tell me what other reason would an in tank pump be fitted other than priming the system,the inlet on the in tank pump is directly from the bottom of tank & the outlet is directly to the filter housing.
ive fitted a vac / pressure gauge to the leak off pipes & ive found whilst running i actually get 7 psi at the leak off? which is pupm pressure , then after a 20 minute rest im seeing a small vacum at the leak off ?
also whilst running there is no leak off from either of the injectors.
we are so used to massive leak off rates with common rail systems this seems unusual, your thoughts!
