hey all,
I've got a 10/72 build 1.7 and it came with all the FI components in a box, seemingly rebuilt..Im currently working out where the hell it all goes and what connects to what. Some diagrams Ive found show a decel air bypass valve and some dont. Does anybody know for sure if a late 72 (titled as 73 ) car would have one? its the only thing not included in the box of bits. another question..air filter. Its the round plastic housing. Has anyone worked out which commonly available (wix,K&N etc..) air filter fits nicely in these? part no. would be great. Thank in advance. (I don't post much as I've found the answer to nearly every question I've had so far in the archives of this site.. very handy!) Just recieved a huge box of seals from 914rubber.com, so off to the garage to fit it all up! (IMG:style_emoticons/default/idea.gif) |

72 should have a decel valve. My old 72 did. I think only 70-71 did not.
Your air cleaner is an oil bath air cleaner. It doesn't use a paper filter. Open it up and put any weight oil in it up to the fill line. Edit...I just saw you said your car is titled as 73. Model year is determined by VIN, not build date. If your VIN starts with 473...you have a 73. I think 73's might have had a paper filter in the air cleaner. I'm not sure when they switched. Someone else can verify. |

Unfortunately, the filter is no longer available. There's a NAPA filter that is close (there's a thread on this forum about it), but you need to make an adapter plate for the bottom to make it fit -- the filter is the right height and right O.D., but has a larger I.D and won't seal on the bottom of the filter housing without an adapter plate. |
