[DML] Re: Dead fuel pump? update

["cbl1739" <cbl302@xxxxxxxxxxxxx>]

eremhcel,


If that is the case,try blowing out the fuel lines(with compressed 
air) UPSTREAM of the fuel filter,BEFORE replacing the fuel pump.
Disconnect the Fuel Line,from the fuel filter,on the inlet side and 
see if you have pressure,if you do your fuel pump is fine,then the 
chances are you have a blockage or something,such as a piece of 
Teflon tape,somewhere 
upstream of the fuel filter,and you must do as above.Also check the 
fuel Dist.to make sure no stray pieces got in there,otherwise you may 
have to clean/possible replace the fuel distributor..
NEVER EVER put excess Teflon tape on the thread joints,only put it on 
the thread part,and then NOT on FUEL LINES,as the fuel could actually 
cause the Teflon tape to disingrate,(any part of the Teflon exposed 
to the fuel)and cause parts of the tape to flow with the fuel,causing 
a partial or FULL blockage,somewhere in all that spaghetti of DMC 
fuel lines.....In other words you are/maybe *screwed* ...you may get 
it all out..but then you may not.You may be cruising along just 
fine,when that *one* missed piece(upstream of the fuel filter) in the 
fuel system,starts acting up,and blocks off your fuel flow or causes 
you grief while driving.
Hope this helps...Hope other DML'ers  learn  something from all 
this...DO NOT use PLUMBERS Teflon (the white stuff) tape on fuel 
lines...Period...
