Preping for a trip with the old girl and have some maint. Q's I need to have answered...

1.Whats the Cummins PN# for the hard fuel line between the LP and filter housing?

2. Is there a difference between rubber gas line and rubber diesel line Y/N?

3. Can I test for fuel line cracks by pressurizing the fuel tanks w/5psi or so?

4. Is there an online wire diagram for my 90 Dodge CTD?

5. A 90 CTD has a Wax KSB and always has 12v+ applied with key on right?

Thanks

Jason

 

#'s 2,3,5 are yes! I don't know the other 2, sorry! I bought a service manual, got all the schematics in there.

 

Beats me on #1 if it's for the stock pump. The piston pump tube number is in the sticky.

The '91 wiring diagram in the sticky will work for almost everything on your truck. What system are you looking at?

Do not buy gasser fuel line. It turns to mush after a year or so.

 

Yes and no.

Some line is only good for gas.

Some states right on the line "gas or diesel".
