I want to put a points SU fuel pump back in my 64 B. It's a November 1964 car and it appears that the pump changed sometime earlier in that model year. I see references to "up to #44438" and "from #44439". Is that a body number or something else?

The NAPA pump that was in it runs constantly and annoys me. Yes, I am easily annoyed.

Those #s refer to the VIN

My Apollo's VIN = GHN5UE346515G

Application would show ......346515

A 1964 and before fuel pump has male fittings sticking out from it. The 5 main pump has female fittings for banjo bolts. Which does yours have? Let me know if I can help. Thanks. Basil 707.762.0974 basiladams@yahoo.com

If you don't know to what Basil's referring look at #6 and #33 below - #6 is 1331 pump

New brakes all round including all pipes in SS flex. Interior redone. CAMS approved roll bar and side bars. Lots more. Hybrid of o/e and show/fast road car. Not for sale - it's my toy!

When I got the car the original pump was gone, replaced with a NAPA pump and regulator. Of course all the fuel lines have been hacked off so I will need to adapt anything I get. This is a late 64 model with a 5 main engine.

Are the different pump models just a matter of different hose fittings? I can probably find compression fittings at the local hardware store. Banjo bolts, not likely.

Jeff,

Local hardware fitting will not fit the BSP threads of the SU pump body.

Put a request on the BST forum for a previously loved SU pump. Then send it to Dave Dubois for a refresh.
Doing this you will be guaranteed to get a fit on the car that works without modifications, funky hoses, superfluous clamps etc.

Enjoy trouble free and quiet drives! grinning smiley

Bruce, just found a used 1307 on eBay and ordered it. I also ordered a couple banjo bolts and hose barbs from englishparts.com. I post the results.

Good on ya Jeff. smileys with beer

Install this correctly, both bracket/grommet and orientation, (bowler hat shaped chamber pointing north) loose the pressure regulator, install new correct size fuel hoses, and a filter just before the carburetors under the bonnet, and you will be good to go.

Jeff,

FWIW worth I rescued my SU pump, when the threads stripped in the body, as in the attached article.

Herb

I actually wound up doing both ports.

Jeff - some info toward the end of the following thread about trouble I had with the new banjo bolts and the hole being too close to the bolt head. You may not have this problem, but I couldn't get them to seal. Be interested to see a photo of the bolts you receive.

Mmm given the Factory didn't think it necessary why do you - unless it's to do with crap in the fuel including breakdown of the fuel line (by using "rubber" ) caused by today's fuel recipes?

PS I had an inline filter but removed it as I couldn't get a decent seal with my Speedflow100 line.

Edit - bloody smileys!

A rather odd query, and I guess to me?

The factory did install a fuel filter just before the carburetors, why do you think, "the Factory didn't think it necessary" ? confused smiley
Factory parts list call up a BMC/BL fuel filter part number.
Factory publications, workshop manual & driver handbook show this filter in place.
Many cars fitted with the predecessor to the HS type carburetor were fitted with H type carburetors that had a 'designed' filter at each float chamber inlet.

As well considering most of these cars have suspect fuel tanks and sit around more than they are driven an in line fuel filter installed just before the carburetors is common sense.

Carry on

Herb, nice fix. I think that may be better than banjo fittings. If I can't find decent washers I may go that route.

Herb, I just received the used SU pump I bought on eBay. Sure enough, a 3/8 NPT pipe plug fits perfectly. Your solution is going to save me a lot of time and trouble.smileys with beer

Glad to be of help.

If you wind up using two 90 deg hose tails, you will need to trim one back, so it can rotate past the other one.
