Casual fire this morning - Regulator?!?

[Waspy]

Good progress today!

Everything connected up and turned the key. It ran rough for a couple of mins, I blipped the throttle and it died.

Had another look with just the electrics on and could see smoke/fuel vapour coming from the air intake duct. Switched off and investigated. As it happens, fuel is being forced through the vac line between the regulator and the TB! This is either a cause, or effect of the fire. But troubling. So my conclusion is that my pressure regulator is dead.

Can you buy new regulators, part number? Any other thoughts on the matter?

A bit gutted as I would have liked to drive it back too leeds today, but rather still be here that on fire on the A19.

I guess the diaphragm inside it got burnt up via heat conduction through the metal casing during the fire. (Edit: or by direct contact with burning fuel inside the case!)

Not available at VW any more, but ECP do one: http://www.eurocarparts.com/ecp/c/Volkswagen_Golf_1.8_1991/p/car-parts/engine-parts/fuel-and-engine-management/engine-management-switches/?440440070&1&a9ee5e59b78eff2b8147b7183af163965fbad100&000477

Not cheap I'm afraid.   

I replaced mine a couple of weekends back, while doing the fuel hoses.  Not sure the old one had any problem, but I already had a new one so I fitted it.
I guess if I suck/blow into the vac hose port and it doesn't come out anywhere else, it might be better than the one you've got; wanna buy it off me for cheap (if it passes the above check)?

Cheers for the link! Some parts are so easy to find on the Mk2, others are just a pain.

I would consider buying yours if it is sound! I don't mind spending 70 quid for a new part as I know it won't burst into flames. But if it's a part that generally doesn't fail or wear out (unless in a fire) then I do t mind using a used part.

Right, I just grabbed it out of the garage, and the diaphragm does hold vacuum.  Do you want to PM an offer and a  delivery address to me?
The o-ring seems to have gone missing from where it plugged into the end of the fuel rail, but I would have suggested replacing that anyway.

100 flawless miles tonight!

Big shoutout to Santiago for getting a regulator to me so quick. Worked a treat. Although this weekend wasn't all smiles and laughter.

So I was only able to work on the car one day this weekend (today). Started with the regulator fitted and turned the key. Didn't fire. And so the diagnostics began. But basically there was no spark to the plugs due to seriously corroded dizzy contacts (corrected due to the trust fireman's hose I would imagine). Ran down to my local independant car parts place and amazingly, they had one in stock! Went back, got it fitted and woop, it started. Now for some test drives.

Test 1: Super short, less than a mile. Drives okay. More worryingly, no brakes! Or very little anyway... Popped the good and rechecked the servo vac lines. Hidden away was a big old melted hole I had missed first time! Cut out the section and replaced with some leftover hose I had from the rest of the servo vac lines and tested the brakes. They worked.

Test 2: Couple of miles, no faster than 40. All good. Gets hot quick. But doesn't go more that half way.

Test 3: Longer blast on some fast roads. Smiles all round. I have missed you old friend.

100 miles back to Leeds: perfect couldn't fault it. Until I stepped out and noticed I was missing a rear bumper  who knows where that is. FFS.

MOT booked for this Saturday. Let's see.
