More on mechanical fuel pumps

[hymodyne]

suggestions as to a good source for pump rebuild kits for the GT6 MK III would be appreciated, as my project nears that stage. I have what I believe to be an original pump on the car, one with a priming lever below.

Something is rotten in Denmark, er San Juan!!!

What I mean is there is something very unusual here. My first TR a new 67 TR4A was driven over 100K , my TR250 since 1985, with maybe 15K and no fuel pump issues, same design, etc. Could there be a local additive that we don't use stateside. Are there other lbc'c on the island? Have they had pump failures.

I agree with Paul - need a careful autopsy.

Other LBC's in Puerto Rico?

Well, let's see - there's at least one other BCF member there who knows Tinster. And I'd bet the local AAA office could identify a few LBCs.

There's the second annual Classic Car Gathering at Plaza las Americas in San Juan, running January 17 through January 30. Barry Meguiar and Dennis Gage will be taping for their TV shows.

There's the Great Antique Auto Fair in Guaynabo, February 19 through 21. Over 1000 cars will participate.

There's the Collector Car Expo in Ponce, February 25 - 27.

Then the Antique Automobile Club of America, Puerto Rico Region Special Meet, March 12 and 13. Also the Thirteenth Annual Fair of Classic and Historic Cars in Aguada, March 20.

Probably be able to find one or two folks who know about any fuel quality problems on older cars.

Hope this helps!

Hym,

I used kits for these fuel pumps from TRF. And they have upgraded theirs since with a better bottom shaft seal. In the meantime, I found this company that uses aircraft grade neoprene in their pumps and the valves are top quality as well. They have kits for everything and a lot more.

Then & Now Automotive in Weymouth, MA and I have NO financial interest in this.

Many thanks.

I'm going on 8.5 years and many miles (40k+?) on my original pump, so I'm going to have to agree that there are more insidious forces at work here.

John- after pondering for a day, I have to agree, something else is going on.

Two TR6 possiblities occur to me. I was making a test run after I installed the new chokes and rewired the ignition. Air box not installed, carb heat shield NOT installed. Gas station 1.1 miles from home- ran at 70 MPH most of the short drive. Got gas. Car would not start but the engine spun easily. I cleaned the points, tightened all the ignition connections- Car cranked right up

Drove 300 feet to the mall traffic light, sat thru red and car died. Surrounded by cops and hundreds of angry horn blowers I opened the hood and could see no gasoline in my glass fuel line cylinder.

15 minute with half the world [censored] and surrounded by cops I changed over to the electric fuel pump. Car started right up and I drove home. Car died pulling into the garage. Not a drop of fuel in the glass fuel cylinder.

I am now thinking vapor lock or fuel filter. I have to put the rear on jack stands to check the fuel filter. What do you think?

Two different pumps cannot be bad on the same car....

 

[Andrew Mace]

Dale, it might have been something as simple as a vapor lock type of issue? It's entirely possible that installing the electric pump didn't really "fix" anything; rather, it was perhaps a coincidence that the 15 minutes involved in doing so was enough to cool things a bit? Just guessing here....

I'm with Andy on this.
If I remember right he has a carb shield. Time for something else

My Spit is approaching 12k miles since late March with a mechanical fuel pump. No problems at all. My carbs, on the other hand, well, that stummbling and missing have got to stop sometime soon...

Easy: Soon as the fuel line gets completely clogged, you won't have any stumbling and missing at all. Usually happens at a very inappropriate time of course.

(I'll crawl back into my SNOW COVERED cave now.)

Don- I think I am narrowing thigs down a bit. If you remember I installed a custom made, insulated carb bowl shield. It was NOT installed on Sunday.

The electic pump is still connected, I opened the gas tank cap, and I cranked the key, this morning, gas flowed, the car started easily, ran 30 seconds and died. Would not start again even with fuel showing in the glass cylinder.

I put the car on jacks and the fuel filter look "fairly" clean.
Might as well change the filter while the car is on Jacks.

At least I made it home under it's own power.

regards all,
