You will need to make or buy a gasket for the cold start valve and mount it to the plenum. That will seal the plenum from a very large leak. You should be able to start it without a functioning CSV but plan on replacing the melted one. It will be OK as a temporary plug.

Can I just get some gasket maker, plug the CSV back in and reconnect hoses for now? The electrical connections look ok, it's the male hose connections that appear to have had an issue.

that's what I do! Group: Members Posts: 20,065 Joined: 27-December 02 From: Port Hope, Ontario Member No.: 26 Region Association: Canada |
That's not how that hooks up, the part on the left is the fuel pressure regulator.
Ljet fuel in goes to the 3/4 fuel rail then to the CSV, then to the fuel rail 1/2 side then the presurre regulator (that's bolted to the tin upright just past #1 and a hose across the back to the return line. Add to your list all new fuel hose 5/16" (close enough to 8mm), minimum rating SAE 30R9 FI hose. Since the CSV is part of the fuel line I wouldn't connect it till you have a better part. |

QUOTE(Mark Henry @ Apr 22 2021, 06:59 PM)  That's not how that hooks up, the part on the left is the fuel pressure regulator. And not the correct regulator for L-jet. That's a D-jet part. The L-jet regulator is not adjustable and has a small vacuum hose running to it. Yours should be in the left rear corner near cyl 1 |

Watching closely, it looks as though there is a mix of D jet and L jet parts.

That’s just a photo from my parts shelf. The D jet regulator likely came off the 72 914 I have waiting to be transformed into a rally variant.
That’s not say the PO didn’t throw the wrong part on my 75 so please let me know if something in the engine looks like it belongs back on the 72 |
