fuel pressure

Every time I leave my baby for more than a few days without starting the engine it takes foever to get the fuel back in the system - have to use the lever on the fuel pump and jack that back and forth for quite while. Any ides as to why this is happening?

Not sure exactly why they do this but on my 69 the PO has both a mechanical and an electric hooked up on the same line. The electric has a toggle that I throw on to prime the motor, it starts right up even after not starting for weeks. Without it it takes forever to crank. It seems to work either way the same-I try to remember to turn it off but sometimes I forget and leave the electric on when I drive (kinda like the parking brake and turn signal...)

is that electric pump stock on the 69? If not, could you provide me with the make and model and basic hook-up details as it looks like I should be considering adding this - despite my attempts at staying as stock as possible.

I highly doubt the electric pump is stock, but it is tastefully done, the toggle switch is hidden under the dash with no new holes cut. There are two things I'd recommend; putting the elctric fuel pump as far towards the tank as possible, and using a low pressure pump, 99% of cars use a higher pressure pump i.e. 35 psi, while you need a low pressure one, under 10psi if memory serves me. The added bonus is that you already have a spare fuel pump should one fail..good luck, Duane

The inner workings of the fuel pump include one way valves that keep the fuel moving towards the carb not the tank. Sounds like yours (or at least one of them) are failing. when it gets bad enough, the fuel will not pump, just move back and forth as the diaphragm moves. best bet is to get it rebuilt before it fails completely. rob

Neither of my 2 have the the hand pump. You can get your fuel pump rebuilt at Then & Now Automotive. http://www.then-now.com/

Thanks for the tip re the pump itself. I have 4 or 5 in my parts bin so will swap out until the problem stops. I believe only the early rigs had the lever for priming. I only have one other of these and the rest are without the lever - which has a neat rod that slips through a bracket to make it easier to accuente the lever.

I have 2 Patrols that have the fuel pump with the primer: a '64 and a '68. I was very surprised that the '68 had it, because I thought it was only the early Patrols that had it. Could be that it was replaced at some point, but this Patrol is all original with only 52k miles.

Also, I find that the Rochester carb takes a lot of pumping to get it started after sitting. I have 2 Patrols with the Hitachi carb - 2 pumps and they start!
