1965 Fuel Injection

I've just moved to N.E Pennsylvania, ( Berwick ) and am in need of someone who is familiar with 1965 Rochester Fuel Injection. I had the unit "rebuilt" by Jack Podell ($1500.00 ) about a year ago and just recently re-installed it on my car. It used to run just fine until the seals began to leak gas due to using 104 octane Sunoco racing fuel. ( Not a good idea according to Podell ). Now it seems to surge and /or buck when cruising at a steady speed or under moderate acceleration. It seems to run OK under hard acceleration. I've been using premium unleaded with Podell supplied lead additive/octane booster. Any help would greatly be appreciated. Thanks.

P.S. Are there any Corvette Clubs in this neck of the woods ? Thanks again.

One of the really good guys on fuel injection is Jerry Bramlett. Unfortunately, Jerry is in Alabama, but you might get in touch with him anyway. He runs them on a car, does some test mileage, and they are ready to go when you bolt them on.

He is easy enough to find, in NCRS Driveline, on the NCRS Technical Discussion board, and on Corvette Forum.

A friend of mine just got his '65 rebuilt last year to run on today's fuel and bring it back to pure stock, not cheap but I'll ask him for the names of the folks that did the work for him. One issue is the gas off is so quick there has been more people going to a heat isolator between the injection unit as well as the naturally aspirated engines. It drives out great and is one of the reasons I'm back in a '64.

I'll talk to him Monday. As far as clubs take a look on the NCCC site for those close to you.

IMHE most fuel suspected drivability problems are caused by faulty ignition. I suggest you use a good distributor testing machine to check the advance curve and particularly for any sign of sticking or jumping advance weights or vacuum advance. New distributor bearings may be required. This is not an expensive or difficult system check and satisfies the rule of checking the easy stuff first.

Good luck YMMV

When I raced my 1964, had 65 FI, the biggest problem was wear on the pivot holes on the diapham attachment. there was a standard and heavy duty diaphram assy from Chevy, but do not remember the differences and part numbers would mean little these days. The Die cast units ran rich when the diapham screwed up while the sand cast units ran lean. Die cast controlled the return line and the sand cast metered the feed line to the injectors.

The work was done by Gail Parsons 740-344-8010 in Newark Ohio, he has grown old with these units and getting to the point of cutting back but he's still in demand around here. We're going to take them, '64 & '65, on a 300 mile trip this weekend so we should know what it performs like by Monday.

The '65 ran poorly at speed, long story short the feed spider is in it's fifth configuration and the version he had was not feeding enough fuel at speed. New one of the fifth design from Parsons is in and we're headed to another show this weekend, will let you know how it runs.

I hate this weather, top is going to be down so much I won't be able to get all of the wrinkles out but I'm used to that at my age.
