Fuel pump splice

[koda2000]

Opinions/Experience?

I'll be installing a new Bosch fuel pump in my '00 AWD Mountaineer later this week. I'm assuming I'll need to replace the thin-terminal connector with the wide-terminal connector that came with the new pump (as my other '00 Mountaineer had the thin terminal pump). My last pump (an AixTex) came with a thin-to-thick jumper wire, which was super easy to install. If I have to cut the old plug off and splice in the new one, I'd rather solder the wires together and use shrink wrap, rather that using butt connectors. Does anyone know if shrink-wrap will stand up to being submerged in gasoline? I know the red crimp-on butt connectors will not dissolve, but I don't like using them if I can help it.

I don't know about the shrink tube question. There are types of shrink tube that definitely will last in gasoline. The normal stuff we all have may eventually break down.

There is no way that I would install a fuel pump with crimp connectors though. Crimp connectors have no business being used on pretty much anything, but especially something that hard to access. I would solder them for sure. Just clean up the gas first and there shouldn't be any problem with fire. Obviously don't use an open flame soldering iron. If you are really worried, use a fan to blow any fumes away.

Of course, the other approach would be to get a Ford pump which should have the right connector and last longer.

Koda, I suggest you also replace the rubber line running
from the regulator up to the hard line. Mine had a split
that was hardly noticible, and would have soon failed
had I not noticed it.

Use a 30R9 type on both soft lines, not the 30R7
the parts stores might try to sell you. You can usually find
it prepackaged on the shelves, but not on the rolls they
cut from. It'll have 30R9 printed on the side of the hose.
I'd also use the true F.I. clamps instead of the more
common screw type.

I used a Bosch replacement pump in my 2000 last
summer, and it came with the jumper wire adapter
in the box...
