I am trying to install an inline fuel pump on my 01 Cavi (2.2) to replace the OEM one that has failed me three times in the last four years. I am wondering how to install the new pump onto the hard lines that are present after the filter. Do I need to have the lines flared or anything like that? Any help in this matter would be greatly appreciated.
While I would encourage you to actually replace your failed pump with an OEM replacement, to answer your questions...
You have to look at the pump you are installing. What kind of fittings does it have? Nipples for rubber hoses to be slipped onto, or screw-in/on fittings.
If using rubber hose to fit over a nipple, make sure it's 'FI' rated hose, not just standard fuel hose. Fuel-injection systems operate at much higher pressures than carb'd engines. Standard fuel hose is intended for less than 20 psi.
If your pump has screw-in/on fittings, then you will need to determine the type and size, and then find steel lines with matching connectors already attached. Most often, hard line comes in straight sections a couple feet long, and is carefully bent (using a common tube-bender) for a custom fit.
There is also cutting involved (don't forget to debur your cuts) for both replacement hard lines, and your existing hard lines.
Again, though, you should really consider fixing the issue the correct way, with the proper pump.

Ferrite, many thanks if you have a recommendation for an exact after market
fuel pump to install (although not as effective as an EOM) and any precautions ??
Heres my question, why are the pumps failing have you looked into that even.
Everytime you replace the pump, do you change the filter?
A clogged filter, will cause the pumps to burn out much faster than if you change the filter every 30k or so.
Do you go below 1/4 a lot, the gas is what keeps the pump cool, no gas, equals hotter running pump.
Do you add that HEET, and that cleaner @!#$ into your tank? That stuff is basically pure alchol going in, that destroys the seals on the pumps, and eats away at them.
There is enough cleaner in the gas already, that 10% ethanol in the gas already, is cleaner.

Remember also that the inline pump has to have gasoline in it at all times or it will burn up. That probably means mounting it low somewhere so that the level of the gas is always above the pump.
well I decided to put an OEM pump but have now found that no power is getting to the pump. I checked for voltage at the Fuel pump relay under the hood and got nothing. I also checked IGN MDL fuse and the F/P-INJ (just for @!#$s and giggles) ad both read fine. Unfortunately I do not have the Haynes or Chiltons book for this car and do not otherwise have access to a wiring diagram. Can anybody help me out here?
