The Stovebolt Site Forums The Shop Area Engine Shop Double Action Fuel Pump ?

Took my son to school in the 46 this morning and noticed a real strong gas smell. When I got home, I found my fuel pump to have gone bad, with gas squirting out of the bottom half/on the side.

Since I'm gonna be replacing it anyway (now) I was wondering... Is it worth the extra expense to go to a dual action fuel pump?

I plan on keeping the vaccum wipers, as I've not found anyone that makes a 6-volt wiper motor that will swap straight across for a 46. I really don't want to hack up the wiper motor cover on the header.

Any of you had any experience with these dual action pumps, or had any luck finding a good 6-volt electric unit?

I like my dual-action fuel pump and vacuum wipers. It pushes snow OK.

You might change your oil if there's a chance that gasoline got in there. I had a leaky fuel pump on a '75 Hornet which raised the level on the dipstick by a quart or two.

Wally, Thanks for the reply. I didn't think about the oil, as it was squirting gas out the side, and onto the ground. But, better safe than sorry. (Cheap insurance)

I'm impressed that your wipers would push snow. That's actually better than I was expecting.

Might be worth the extra bucks to go with the dual action pump.

i just installed a dual action from advance auto and it works real well, no snow yet. ron

Wally's right on the oil. Saturday we had to put a fuel pump in a 230. The truck used half a tank of gas to go just a few miles. Had oil coming out the dipstick hole. Drained between 3 and 4 gallons out of the crankcase.

By all means, go with the double action pump if you're sticking with vacuum wipers. Well worth the investment.

Also,do you have a vacuum reservoir tank? It helps,and bigger is better.

I have a queston on this subject. I just put the motor back in my 1953 two ton. I put a double action pump on but have not hooked anything up yet. What do I do about the original connection on the manifold for wipers?
Do I just ignore it, or will it be the same as a vaccuum leak if I don't block it off? Also, the pump has what looks like two connections for hoses. One is marked "Wiper". What is the other one for? Is it an air intake? Thanks, Allen

Wiper: run that line to the wiper motor.

Other: run to original manifold (vacuum wiper) connection.

I put a double in my 55.1. When I went up a hill without it, it stopped imediately. Now, it just slows down a little. My vac motor has not been rebuilt.

Jed,

I took my vacuum motor and squirted 3-in-1 light oil in all the openings and worked the lever back and forth. That helped a lot. Like Tim said, use your manifold vacuum in series as the "fore pump" for your fuel pump. This has worked fairly well for me

TC,

Thanks for the clarification on the plumbing of one of these units.

I'm sure that would have been one of my future posts.

Wally, my motor seems to work pretty well as is, but doesn't sound like a bad idea.

The biggest issue I have with my 46, is keeping the windshield wiper arm from flapping around in the wind, while I'm driving down the road.

The dual action pump won't help with that, but it sounds as though, I'll get alot better and more consistent service out of the wiper motor.

Sounds like I better look at doing the same to my 52, while I'm at it.

Thanks for all of the replies.

Tclederman: Thanks for the answer. Seems obvious, but I never would have thought of it. I assumed the fuel pump created its own vaccuum.
