My 1997 ctd had a new fuel sensor installed last year ,the gauge is starting to fluctuate is this normal or electrical in nature?
any help is as usual greatly received,thanks Mason.

 

Hello there Long time since my last visit, however i just had a new lift pump installed ou my 97 12 valve ctd,along with a cold start selenoid,since it got out of the shop the temp. gauge reads hot 220-230
under no load what do you guys think? I'm baffled, any help is greatly appreciated!

 

For your fuel pressure problem, installaing a snubber apparently takes care of the problem.

Here ya go ... SNUBBER

Why installing a lift pump made your water temps shoot up that high is beyond me.

 

Are you talking about fuel pressure or fuel level? Oh yeah, I put a snubber on and it still fluctuates at idle.
