Now that I have my injector housings out,I am wondering if the injectors in there are factory or aftermarket?

There are no name brands on the injector....The serial numbers on the side are

01D109B......21lbs....( Don't know off hand what they flowed from the factory,car is a 91.)

Of course I googled the serial numbers..And of course so many sites come up..

I was wondering if any of the technically advanced members would know this off the bat...Car has 43,500 miles....Bought the car with 41,000 miles back in November...

Never had a fuel issue so far..( knock wood)

These are what I put in my car. I bought them from Amazon as I had $100 in amazon dollars already.

Hmm I thought all Accels were labeled.... Just like the RCs

However if they are indeed Accels they have stainless inserts.

You'll want to get the "O" ring seals (new) from Jerry, and let him know (I'm sure he'd ask) that they're for a 91. Also, Jerry has the proper gaskets as well.

Is you motor top end ported? If so, of course you'll need to cut the gasket port holes to match the porting. I use an exacto knife after plugging the runner with a oily rag first.

Check w/ Jerry, but I don't use any gasket sealer on the (under side of the) gaskets, except for sealer around the coolant port. However, before placing the gasket on the motor, I DO spray the plenum side of the gasket with silicone lube to act as a release agent. In this way, next time I need to get under there again, after removing the bolts, I can slide a thin putty knife between the gasket and the plenum and slide it down the length of the gasket (on each side). This usually results in the gasket sticking to the IH, but frees easily from the plenum. I've re-used that gasket up to 3 times w/o leaking, if I'm lucky enough the gasket doesn't crack anywhere first. (In any case it should be good for at least 2 uses!)
