My 1984 Audi coupe GT for about a month I would have to crank and hold down the gas for about 10 seconds before it would start and finally it wont start but will crank and we tested and it does get spark so we are fairly certain that its a fueling issue i am wondering what it could be, like a fuel pump or if something else in the fuel injection system.

we actually found out it was, the air filter had like a bees nest in it so i wasn't getting air so now i'm going through and just going to replace all the filters and change the oils. But I am running into that cant find the little yellow plastic fuel filter unless they where changed from plastic to metal aftermarket? i also have 2 fuel filters and am wondering if there are 2 to began with or if someone added the second on later?

On my car, Bosch part number 71031 is listed as the primary, but a footnote says a secondary filter is required. What's even more confusing is what Bosch shows as the primary filter (before the pump) looks exactly like what everyone else shows as the secondary filter (after the pump). Every part supplier lists both a primary and a secondary fuel filter, but just like Bosch, most show the same part for both. My uncle, who was the original owner of the car, said he's only ever seen one filter on the car, and I only see one mounting location for a large secondary filter. You could probably find an aftermarket one that fits, but the outlet from the tank and the inlet to the pump is 5/8", which is pretty big.
