Here’s a 2013 article from the Stromberg website that I wish I’d seen earlier, I can 100% confirm the accuracy of the findings!
Will take the advice in the article in terms of the K&N element and see how it goes
From the article –
Our buddy Lez dug into his legendary vintage magazine stash for this great Street Rodder magazine tech article all about choosing the best air filters for your Stromberg 97s. Written by the highly esteemed Ron Ceridono back in 1998, with input from Stromberg expert Jere Jobe (from Vintage Carburetion North), it is, of course, just as relevant today as then. Sorry about the quality. It’s a scan of a photocopy, but if you click on the pages below, they will come up at a readable size.
While it’s well worth reading every word – hey we’ve even thrown in a free Dick Spadaro ad – if you’re looking for the ‘executive summary’, it’s this….. “if you have an air filter on your 97, make sure it’s a K&N E-3120”. Here’s why: Click the pages below to view, or ‘right-click’ this link to download the 2-page pdf. Choosing The Right Air Filter
Most vehicle repair shops are encountering a lot of fuel-line-related issues since the introduction of ethanol into America’s pump gas. Because of ethanol’s effects on rubber, plastic and metals, they are finding themselves spending a lot more time fixing fuel delivery systems than they did in the days of leaded gas and carburetors.
After my previous woes with the carburettor and refitting the cracked item for the time being I still had the slight fuel leak from the fuel inlet/screen area. After annealing the copper washers there was still an issue. To solve the problem I’ve changed to fibre (fiber) washers, so far so good.
I’ve been investigating the fuel screen on the Model A’s fuel tank filler neck.
Purchased the item below from O’Neil’s, however it would appear that there are three different types:
Drop in with tabs
Drop in without tabs
My filer neck appears to be made to accept the drop in with tabs type of screen. The item I’ve purchased has no tabs and it appears it would be a really tight fit. Rather than destroy anything I’ve posted a question to my friends on the Ford Barn forum to seek the best way forward.
