Thats a fuel pressure regulator..

You have a 1991 so you can only use the lines (and fpr) from a 1991 and early 1992 vehicles.

DannyBoy broke his FPR line (farther down) and I believe he got a set of lines from 410Fortune (I think). He was then able to use a FPR from a 1992/1993/1994 Explorer. The later fittings on the FPR a normal wrench style instead of a funky connector like yours has.

It's going slow here.. Too much time at work and in the stable..

So, if I understand right, the FPR isn't in anyway different in the 91 - 94 models except for the way it connects to the lines? Get a newer FPR and other lines and it will fit?

There are 3 freeze plugs on each side of the block.

You can see 3 of them in this pic.. (they are shiny copper looking round things on the side of the gray part of the engine).

What worries me though is if they are all like that, you may end up with a leaking on at the back of the motor. To get to those you have to drop the transmission.

My guess is that the PO (previous owner) didn't maintain the cooling system and you got corrosion started.. The engine needs to be flushed with some cleaner (acid cleaner) BUT the corrorsion may be the only thing keeping those freeze plugs from leaking so you could be taking a chance by running the cleaner through it. Its like switching a neglectec engine to synthetic fluid. The synthetic may help get rid of the gunk in the engine which could make leaks start as the old gunked oil was what was keeping it from leaking.

I have to drop the transmission? Because? Are there three on each side and a couple on he back of the motor? Or do I misunderstand? Or I simply can't get to the three on each side without dropping the trans?

That is correct.. I'd contact DannyBoy as he is the one that actually did this change recently...

You would drop the transmision to get to the freeze plugs that are on the back of the motor.. You can get to the ones on the side w/out dropping the trans (can be a little hard to get in there, but you can do it)..

The ones on the back of the heads are already getting changed since your replacing/rebuilding the heads...

I only mentioned possibly changing the rear ones because if some are corroded, are the ones in the back bad too? You could always wait and if the ones in the back of the engine ever let go, then pull the trans and do it..

Thanks! Yeah, I guess they might be a problem too.. But droppig the trans.. That's scary! Have done a lot of work on the car this far, but..

If you get a later model FPR you also need the 18-20" fuel line that matches up, otherwise it bolts right up.
