1984 P30 Hydroboost Pump Diagram

Restoring a 1984 motorhome on a P30 truck chassis. It has a 454. I did not disassemble it and I think I'm missing some brackets for the Hydroboost pump. The "new" engine is a 1990 crate engine that the previous owner said had hydroboost brackets on it. It had brackets, but nothing that appears will work with my pump. Diagrams would be a big help.

    I did the google search - thanks. Nowhere could I find a picture of the bracket detail, like from a factory service manual.

SOURCE: 1983 chevy 454 wont stay running

If it's an electrical problem it wont start at all. If it starts, runs or a few, it's a fuel issue.
A new pump and lines, what about any inline fuel filters and the fuel filter in the carb fuel inlet? If it has a quadrajet carb, the fuel inlet filter will play with you.Check your idle speed and the auto choke setting.Any questions on how to balance the carb and set the xhoke, Feel free to ask. _NNed

1990 chevrolet p30 motorhome chassis 454 engine automatic I replaced turn signal switch The horn works BUT it also blows when i use the turn signal

Since the horn wire is just a ground for the horn relay there must be a hole worn in the insulation of the horn wire and that is grounding to the chassis when you use the turn signal switch. no other explanation.

I have a motorhome make Honey 421S with a chevy 454. the choke light stays on, and it smells like a gas station after a ride. Consumes lots of fuel and I don't understand the vacuum system. Anyone can...

Update? If the Motorhome has a carburetor, its pretty old and has a P30 chassis. Gm makes the truck, Honey makes the camper. Check the electric choke and make sure it has power to it when the engine is running, if not check all fuses. I dont have a diagram to see where the choke gets power from. Make sure the choke pull off is working, its a little vac can on the right side of the carb, if it leaks, it wont pull the choke flap open. Anyone that works on Quadrajet Carbs can fix it for you.
