inline fuel pump for 454 chevy

[goducksgo]

Had a 82 winne with carb 454.Ran great til got warm then had very poor accel.Noticed it had poor fuel flow in carb when floored it.(looked in carb going down road with dog house off)New filter no change? New carb no change,etc. Dropped tank to check for plugged sock filter and found rubber fuel line was getting pinched between croo frame and tank! Hose stayed patent when cold but got soft when hot and then would squash flat. One snap tie to hold away and never another problem.

Don't forget to look in the Tank, some have a screen filter at the end of the pickup tube.

Mine had a mechanical fuel pump on the right front of the engine. I replaced it early after I bought the rig in '98 with a new pump I bought at Car Quest. It was still working fine when I sold the rig in '05.

My problem was the carburetor was starving for gas on hill pulls.

Max, I know you sold it. But when my switch blew off of the oil pump, I lost the pump in the tank. MH ran fine on the flats but when it came to the hills I had to easy foot it. Once the switch was replaced no more problems on the hills. I wonder if your tank pump was bad?

I have a 1985 Holiday Rambler. It was running up until a week ago when I parked it in the driveway and now it won't start. I started replacing vacuum lines because all the old ones are falling apart and thought this might be the problem but it is not. If I pour gas directly into the carburetor it will start right up and run until the fuel runs out. I recently had a new fuel filter put on it. Any thoughts on what it might be? This is a 454 gas engine.

Well since you have indicated the "Rubber vacuum lines" are falling apart I would expect the rubber fuel lines are also.
For this your tank will no doubt hafta be dropped e'nuf to obtain an easy replacement reach.
I use only "Fuel injection rubber" which is much more expensive but it will last a lot longer.
Once all of that rubber is replaced (Including the Generator which is smaller) look into the small filter inside your carb.....
Last suspect on your list will be the manual engine fuel pump which IMHO are a PITA to change out.....
