last visit: Sat Nov 21 19:32 CST 2009[RELATED]...with everthing operating normally, (that is, no extra abnormal currents added in...this is possible with a motor if it working harder than normal for some reason, the extra load requires motor to draw more current to maintain constant speed) warm wires indicate too small a gauge wire for the currents passing through them...
I suggest you measure the current and determine if it is normal or raised, then proceed accordingly...short of making an engineering investigation out of it, you may just want to increase wire gauge...
Additional:
...warm terminals indicate a poor connection (either due to corrosion, or a bad crimp...which can be as simple as not getting all strands into the crimped area...effectively decreasing the cross-sectional area for current conduction, or some combination of the two.
Use Anti-Corrosive-Zinc-Paste on terminals, especially those under the vehicle and subject to even more environmental nastiness, NOT "dielectric paste"...why anyone would want to put a total INSULATOR on electrical connections is beyond me!!! ...maybe because the word dielectric has the word "lectric" in it, so it must be good for 'em...WRONG!

last visit: Fri Nov 13 14:43 CST 2009[RELATED]Thanks!! The wires to the pump are broken somewhere before the pump, as when I move the harness it well stop or start working again. Going to replace those with heavier wire. Went to get some Anti Corrosive Paste at the parts store but of course it seems no one has it. Where do you get it? Thanks for your help!
John

last visit: Sat Nov 21 19:32 CST 2009[RELATED]John;
An intermittent condition can be due to fatigued wires where the strands are barely touching anymore, and that based on position or vibration...there is also plenty of heat produced by the arcing and sparking (plasma!) which occurs as the connection comes and goes, so you may be able to follow the heatsource to the open/interm. problem location. You're probably pretty close to the source of problems...
ACZP is not generally considered an automotive item, even for a well stocked automotive parks house (sure, IPD started carrying it in tiny tubes the size of lip protector balm, but at the rate I use it, and send it out with kits, I need to buy it in slightly larger quantities!)...and what does the automotive chain store specializing in neon-license-plate-frame or blue-LEDs-on-the-windshield-washer-nozzles, know or care about vintage cars and restoration/corrosion protection of their electrical connections?
Buy ACZP at commercial electical supply houses...as you likely read, I highly recommend and prefer Burndy's Penetrox product over the Ideal's low viscosity product (which doesn't stay put!) available at the common chain home improvement/hardware superstores...I have even seen Penetrox offered on the familiar on-line auction site, so you can let your fingers do the walking/ordering, and UPS will bring it to your door...can't beat that!
Cheers

last visit: Sat Nov 21 17:04 CST 2009[RELATED]I don't know if it's normal, but.. I don't like it. you mentioned someone had an aftermarket pump in there.. maybe they did some aftermarket wiring using wire too small... check and make sure any connections and/or splices are clean and properly done.
