How to install carburetor in 1985 coachman chevy van model ay

Get correct fuel wrenches, mechanics buy them at the tool truck. The rest is really easy, this part is really hard. We can expect its a 454? right? has a Quadrajet? and you are installing another quadrajet of the same number? If it still runs, you could ask mr. goodwrench. he can find your needs, be sure it really needs a carb, (we rebuilt them everyday replacing and correcting their list of problems simply) A vehicle that age can need a list of hoses and fuel related parts. It is a potential damaged fuelline fitting I fear for you. The leak later can cause very bad situation. Take it to the best, forget the rest. Mr. goodwrench loves your carb and you, He will not let you down. or let you accidentally spend too much. or have a danger result.

Some vehicles of that vintage had filters you cannot find, but they are there. They had hoses you cannot get to, but they can deteriorate where you cannot see. like inside the tank or at the tank or along the frame. The pump supply can starve, be blocked, have plugged filters, even up to the carb entry where you need the special wrench. and then the flare nut can get damaged by being tighter than a......euphemism..... yeah, this is a job for supertech, or the RV coach service department, truck shop, or GM dealer truckshop. I hope they just fix the thing it needs and you can save the old carb, to simplify your dilemma.

There may also be an adjuster tool required perhaps, that is the last tool to set mixture. You really need experienced help. each step requires experienced judgement, inspection, and the tools, testers, gauges, as well as knowledge of tune up and how its parts relate. Your ignition delivers the hottest spark and your carb delivers the most air and fuel, after 30 years ? some of the emission ...parts... can be deleted. it would run better, cleaner, and safer, lighter, and eliminate them as problems. please, at least ask about it there, and get a price for fuel related issue diagnosis.
