What do I to to fix this. My rear carb hits my fuel pump on my flathead. It is a racing weiand intake so the carbs are spread apart farther than normal. I’m sure someone has run into this problem. Sent from my iPhone using H.A.M.B.
I have a different manifold than you but I encountered the same problem. By undoing the screws that hold the pump together, you can rotate it so the inlet, outlet are in different positions.
It’s not that. I tried thag. But that is clear. It’s the mating surface that hits Sent from my iPhone using H.A.M.B.
You need an offset riser. They used to be out there. Dig around. I will look took around, too. Someone else needed one here, too, somewhere. Maybe I will render one in CAD, and see about making some.
Yep. I’ve been looking for a long time. Can’t find one. Thansk for the help. I made a post looking for one but no one responded and moved on thinking I need to figure something else out. Sent from my iPhone using H.A.M.B.
I called in a favor, and have a regular 1" spacer on the way over. I will model it, and then make an offset model. If someone out there has a DXF, or otherwise, of a 3-bolt Stromberg base, I can whip out a model in under an hour.
Just a Q for the uniformed.....=ME. Are all FP towers clocked the same? If not- To the OP, Maybe a different year/model?
What is the distance from the stud on the back to the fuel pump flange? Side rear side of stud, to flange edge.
If you put the fuel pump in, and then sit the rear carburetor on top of the studs, how much do you need to move it forward to get it to clear?
You're probably trying to use the wrong fuel pump. Phil Weiand knew what he was doing! A pre-'49 post war pump should fit OK, but may need a modified push rod. You would be much better ahead to just swap that early style intake for a later 8BA style, like the engine/car you have. The carbs will sit properly angled and you'll have a generator mount.
Supper clean engine! But could u add a pic looking straight down of the intake please. I don't under stand why an 8ba pump is not fitting. It should. Sent from my LM-X410.FGN using The H.A.M.B. mobile app
It’s a mix match of parts. It’s a 8ba motor with a 59a intake with a pcv valve. It will be running at 46-48 fuel pump and fuel pump stand with a cut down 8ba fuel pump pushrod. My rear carburetor hits the front of my fuel pump. No matter which way I clock the pump it still hits. The carburetor has to move forward. My uncle has the same problem. I need this piece. Can anyone find one or have one. I have looked for weeks now. you can see how it lifts the carb up and moves it forward just enough to clear the pump. Sent from my iPhone using H.A.M.B.
Can you cut the bottom of the pump stand off and reclock it? I saw some pictures of 49 pump stands that are turned towards the driver side about 45 degrees. Or make a spacer that will turn it 45 degrees towards the driver side?
My example 3-bolt spacer arrived at my shop today. Unfortunately, I am out at the home office until Saturday. Once I can get it, I will render it in CAD, and see if I can get some time on the mill. I figure and inch-and-a-half up, and an inch-and-a-half forward ought to do it.
Wait a minute. One of your pictures shows a Weiand manifold, and another shows a Fenton. Which is it? From your previous posts, I believe that you have a Weiand. It looks to me that a stock 8BA fuel pump stand would probably be the answer. Have you tried one?
He's showing an example of the offset spacer that he needs. It was once a thing on the market, but has been lost to history.
I will reiterate : Has he tried an 8BA fuel pump stand? If that doesn't work, I will have to admit that it is possible to mismatch components to the extent that you can arrive at a combination that just won't work.
I can’t use a 8ba stand because then I won’t have a breather/filler Sent from my iPhone using H.A.M.B.
That is what I started thinking last night in bed. That is last resort at the moment. Due to the fact I can’t weld aluminum Sent from my iPhone using H.A.M.B.
An 8BA stand is clocked around. No breather tube though. I made an adapter plate for my set up. It was a dual bolt pattern piece or 3/8 al. with the holes clocked around. The manifold holes were countersunk for flathead screws and the pump holes were tapped. It moved the pump around like a 8BA.
