Pulling injectors
 

I will be removing the fuel injectors to have them cleaned on a 500efi. Any advice would be helpfull. I think I'm going to have to pull the intake. Where can I get the Orings for it other than merc. What style injectors are these? Can I reuse injector Orings?
Thanks. Any input would be great!

If you get them serviced at a reputable shop you will get them back with new filter screens and all seals. Make sure you lubricate the o-rings before you put them back in.
Here are a couple I've had good experience with.

Marren Fuel Injection
RC Fuel Injection

call http://www.dpii.com/ ask for jim,he has everything and can also do the cleaning,flow them and new screnes and has the orings..

We use Marren Fuel Injection. www.injector.com. Tim isn't just some guy with an injector cleaning machine. He thoroughly cleans and checks each injector for flow and operation, installs new o rings ands screens. Fuel injection is not a side business for him, it is all he does. He does complete system design for just about anything and is a racer himself (IMSA Continental Tire Series).

We always send them back with new o rings & screens

Also some added info and we offer fuel injector services as well. Read post 10 from the link below. Also have to add about our service that most top feed injectors are 25 to 30 dollars per injector. The range can be 25 to 35 dollars per injector for side feed injectors.-

IMO 4 important things that nobody looks at beforehand on choosing a fuel injector service is, does that service test flow a fuel injector with a test fluid that matches the specific gravity of current fuel blends - this provides more real world results to compare, next do they use a quality machine, next does this service back flush an injector after it has been cleaned with a back flush system, next is before you even pull your injectors, it is wise to number your injectors as to which cylinder you pulled them out from the fuel rail. A really bad injector can possible pinpoint a problem cylinder. I do not think I have ever seen a fuel injector service tell you to mark your injectors beforehand.

Should I replace the intake Orings? If so where is a good place to get them?

Napa has them, but I don't recall the P/N.

Well I dropped them off today, they are going clean, flow and replace seals and filters. $18 per injector and will be done Wednesday. Now hopefully I can find the P/N for the intake o-ring.

Fel pro part number ES 70599.. any of your local auto parts stores will have them if they carry fel pro,,napa preferably..

Thanks!

Oh by the way I'm also looking for replacement orings for the intake manifold

The shop you use should have them. Just take one down with the injectors and see if they can match it.

Getting ready to do this and also curious about said part number? FIXX, do you happen to know?

The shop is replacing the orings on the injectors, but I'm looking for the ones on the manifold that seals to the plenum. They are slightly D shaped

Thanks! $13 per gasket and you need 8! Jesus...

....

$18 a injector, that is a AWESOME price if you ask me wiht new screens and orings.I paid $250. Where did you send them to, or have them done?

Im starting to think the shop that cleaned mine upcharged me now. I bet once they heard :boat:, they added 50% on...:mad:

ausinjection.com best part is they are right down the street. Im picking them up today, so Ill report back. The owner knew right away what they were because of the merc blue paint.

Awesome place indeed! Very friendly over there and close.

Yea they are great, I saw about a 10-20% increase in flow and was able to find the orings for the intake here in town for $1.75! To think merc wanted $13+

That's great! If you don't mind, do share regarding your source on the orings for manifold! Thx

Perfect! Appreciate the help! Good to see a fellow Arizonan on here.

Ran the boat yesterday, it ran great! Idles much better and I picked up another 2mph on the top end. I would recommend this to anyone in the future
