[QUOTE="Fishfiles, post: 35083, member: 782"] I think I know what type of fuel connections you have on that Isuzi , banjo fittings , there are either brass washers on the smaller ones and / or aluminum wahers with an o ring rubber inpregenated in the washer , those fittings have a tendendancy to leak and suck air into the system , I think I read where you hooked up and external tank but would bet you went thru the fuel filter head and tubing , what I have to check for that is an old school Detroit ZDiesel hand primer pump that I have a tee and a gauge mounted to and plumb it into the system which can be chalanginng if you have banjo fittings and not equiped with some adaptors ----- but from judging by the age of the machine , I think you said 80's , I would lean more to compression being low ---------you are right about them Isuzi's not liking starting fluid and locking up , gasoline on a rag held by the air intake is much gentiler [/QUOTE]
