EHA adjusting procedure ?
 

just-n-time here, My question has to do with adjusting the eha,what is the procedure to this job and any related adjustments that might need to be done,at the same time.The reason I ask is that I have seen posts on it and I have not pulled any how to sights up when I attempt to look into it.j-n-t:silly:

What is the problem that you think that the EHA needs adjustment?

Has a fuel pressure gauge been connected & the differential pressure is incorrect?

No doc. I am interested for my own edification,I haven't as yet tested the fuel pressure though I do intend to,just to know what is up in this system,
Most of my problems are air related at this time, vacuum problems and the like. I have found a number of problems and wish to continue checking out the entire unit.
Thanks j-n-t:silly:

To adjust you must first remove the EHA & since is is in the fuel circuit don't do that with a warm/hot engine. Of course the key must be off. Be prepared to have fuel spray from the connection. Have rags available!

To adjust you will need a 2.5MM allen wrench, remove the brass closing plug (screw) & then the allen adjustment will be apparent.

NEVER move the the adjustment more than 1/6 of a turn at a time. Clockwise will create a higher differential pressure & therefore slightly richer at WOT.

Thank you doc. the resetting is not something that would normally be done then I take it? I would like to know ware I can find the procedure so I can familiarize myself with all the other interactions of this setting,so that I can get a better knowledge of the system.
Thanks j-n-t:D

Thank You DOC. the system is all new to me and I dint like being at the mercy of people that talk but really cant do,I have this car now for 11months and I have found so many things wrong that it is sad. I cant say who had done the majority of work on it but it left a lot to be desired.:silly:
