When spraying cabinet doors and boxes what length hose are you using? shortest 1 i can find is 25 ft. would be nice to have a shorter one instead of loading up all that paint in the longer hose. Or am i over thinking it?

Minimum hose length depends on the size of your pump, but you can Google "15' airless hose" and find plenty of distributors. 3/16" 15' is as small as they go before you're in whip territory though.

With that said, what is the longest hose length you can go before you have problems? And how much paint is in say a 50' section of hose?

The volume of fluid in a 1/4" x 50' hose is .50 gallons.
The volume of fluid in a 3/8" x 50 hose is 1.14 gallons.

Short hoses may be convenient for small projects, but using a hose shorter than the specified minimum length for your pump can cause damage to the parts and cost you later in repairs.

Uh....ive never been able to get 50 gallons of paint in any 50ft hose. .5g maybe? And a smidge for the pump....ive never actually measured it but I always plan on giving the pump about 3/4 of a gal on 50 ft. Add another .5 gal per 50 and compensate for overspray. 1/4" line. It's always worked for me anyway.

I stand corrected. That's not a period on my phone screen. It is, in fact, a decimal point. Nice catch! I thought it was probably a typo as the pump repair guy knows a whole lot more than yours truly. Oops! Sorry for the oversight.

I have a 100' on my pump, and it only sucks about 2/3 gallon up. I think each 50' 1/4" hose will hold about 2/3 quart, and the piston takes about 2/3 quart, for a larger pump.

Sorry, my math was off.

The number of cubic inches in a 50' x 1/4" hose is...
3.14 X .125 X .125 X 12" X 50' = 29.43 cubic inches = .127 gallons

The number of cubic inches in a 50' x 3/8" hose is...
3.14 X .1875 X .1875 X 12" X 50' = 66.23 cubic inches = .286 gallons

lol yeah I saw your original post about a 50' stretch of hose holding a half gallon of paint and was about to call you out on it haha! In my experience it's usually a bit shy of 1/4 gallon, filling up the siphon, prime tube and hose. Not a whole lot more for a 3/8" hose, just shy of 1/3 gallon.

I typically run 100 ft of hose. The minimum is 50 ft. I have ran 150-200 ft on some big gas sprayers. I typically use 1095 sprayers. For laquer or spraying door frames etc. I usually use a small sprayer.
