If you end up fixing the old one, post up what size o-ring was required, it will help someone else one day!

Just drop it in and go! Only thing is you have to remove the IP to swap the control unit so make sure you set the engine on the #1 compression stroke's PC mark, remove the IP with a 1/8" drill bit inserted into the side hole, then reinstall in reverse after swapping the control unit. Nothing...

GA 1085 is the external one. They don't list the internal because it's part of CU8514A You'll have to separate the 2 halves of the assy. and see what size o-ring fits in there correctly. If you have any trouble finding one locally I often use...

Hold on a second folks.... He is correct, the throttle control is considered non-serviceable but can indeed be fixed with a welder! So, the assembly ( which can still be purchased if you can find it ) CU4514A has an internal o-ring which is the one that usually leaks, because that is the one...

In addition, if they have been sitting for 10+ years with fuel in them, be very careful not to trash your injection pump. If the IP is gummed up and you crank the motor over you will damage an Ambac M-50 pump and you will turn a Bosch PSU pump into scrap metal. There is a procedure to check and...

It sounds like you plan to take the Aux. fuel pump and remove the solenoid and use it in place of the primary pumps? If so, that will be fine. The 2 primaries are for redundancy, you only need 1 to make the machine run. I often tell people to unplug one of their primary pumps to "save it for...

Ah, you guys were typing faster than me! You got 2 replies in before I could type 1. Sounds like your check balls are not working correctly as well as clogged strainer. Clean everything up and reassemble and test, you should be fine. I have never seen a video, but they are so simple to take...

I wouldn't worry about buying parts for the original pump. If you disassemble it and clean everything including the 2 check balls, plunger and strainer, etc. and it still doesn't work there is nothing else you can "replace". At that point your best bet is just purchase either an Airtex 24V pump...

When you cap the ports, make sure you remove the brass plugs from your old pump and put them into the ports of the new pump, don't just use the caps, that won't work. The cap doesn't do the sealing, it simply forces the tapered brass plugs into the holes to seal them off.
